  • Volume 70 Issue 1 - Compression and stacking strength of corrugated
           fibreboard containers
    • Abstract: Stott, RA
      Australia and New Zealand have produced some of the most innovative research specialists on packaging paper s, both in the government and private sectors. One of the first specialists in corrugated box research was Ron Stott (1920-2004). Ron joined Appita in 1956 not long after he joined Australian Paper Manufacturers in 1955 as a Sales Research Officer in the Research Division, (After many company re-organisations and spin-offs that group is today part of Orora).

    • Abstract: Bennett, PG; Allan, R
      In this paper, two of the industry's outstanding industrial researchers, Pedter Bennett and Russell Allan, both LR Benjamin Medal winners, were able to recount their stories, putting into context their lifetime work, which had at times been hidden from open publication. Although it primarily discusses efforts in an Australian company, their experiences, their successes (and failures) could equally be found in New Zealand.

  • Volume 70 Issue 1 - Monitoring dissolved COD in a pulp mill wastewater
           treatment plant by measuring total dissolved solids with a refractometer
    • Abstract: Toivakainen, Sakari; Kopra, Riku; Hannukainen, Heikki; Laukkanen, Timo; Dahl, Olli
      The measurement of total dissolved solids (TDS) and its correlation to dissolved chemical oxygen demand (DCOD) in different kraft pulp mill wastewater solutions was studied at laboratory scale with an online refractometer. The study concluded that TDS can be measured successfully at a kraft pulp mill wastewater treatment plant in spite of suspended solids such as fibres or biosludge. The correlation between DCOD and refractometer measured TDS was very strong. The estimated ratio between the changes in DCOD and in TDS for lignin solutions was 1.81 to 1.85 and for kraft pulp mill wastewater 1.13 to 1.29. Accordingly the removal of DCOD in a plug flow aeration basin of an activated sludge process could be monitored with refractometer TDS measurements.

  • Volume 70 Issue 1 - Maximising starch benefit on the paper machine
    • Abstract: Williams, Roland; Allan, Russell
      Starch addition makes an important contribution to the strength properties of recycled fibre sheets or papers that have some fraction of their makeup using recycled fibre. Many properties are enhanced by the addition of wet end, sprayed, size press, or more recently speed sizer starch. However, the effect of starch is dependent upon the property being sought, the through-thickness profile (where the starch ultimately resides), the quality of the fibre mix and, in the case of cationic wet end starch, the anionic activity existing in the machine approach system. Often, the results of paper machine trials where improvements in quality are sought from starch addition, give unreliable or inconsistent results confounding the decision making process.

      As starch can be an important cost component in developing paper strengths it is necessary to ensure that the maximum performance is developed from the starch used. A powerful approach for evaluating the likely effect of starch addition to various fibre types and the ultimate strength performance of the sheet has been developed. The method allows component costs to be associated with specific grade designs and, where flexibility in fibre sources are available, allows optimal performance/cost designs to be obtained. In some cases large benefits can be identified in terms of developing paper property while lowering cost.

      Interestingly, for some sought after properties, the lowest price for a given performance occurs by using starch to enhance a heavier, but lower quality, base sheet.

  • Volume 70 Issue 1 - Opportunities in emerging bioproducts
    • Abstract: Poikolainen, Henna; Nieminen, Juha-Erkki; Welsford, John
      Following the increase in digitalisation and decline in graphic paper markets, the pulp and paper industry is searching for new product opportunities. Today's modern pulp mills are already maximising the sales of renewable energy and introducing new processes such as bark gasification. Many companies are preparing future production concepts where pulp mills are becoming integrated biorefineries producing multiple value-added products from biomass. Some of the hottest bioproducts today include lignin, nanocellulose, liquid biofuels and biobased chemicals.

    • Abstract: Woollacott, Steven
      Over 200 food contact professionals gathered in Brussels, Belgium last December for a 360 degree view of the food contact landscape - from ongoing challenges and developments through to regulatory processes in Europe and beyond. The conference saw a multitude of delegates come together to network with fellow food contact industry professionals and gain insights into new ideas, ways to innovate, cut costs and stay ahead of the competition whilst remaining compliant despite the ongoing legislative changes and unclear regulations in different countries. Attendees to the conference included Kimberley Clark, Nestle, United Biscuits, Innovia Films, Billerudkorsn s, Stora Enso, Clariant, Elopak, Tata Global Beverages and many more.

    • Abstract: Jones, Oliver
      Paper and board based products are found as packaging in numerous food industries including horticulture, dairy, meat, beverage, grain and cereal. In recent years there has been increasing concern from regulators and, to a lesser extent, the public that substances could migrate from packaging into food, where they have the potential to be ingested and to potentially form new compounds that are not tested for (or in some cases even known about). Should this be a concern?

      In this white paper by Graham Moore, reproduced from a Smithers Pira article, a 'road map' of the 5 key stages necessary for a paper business to move forward into new markets and products is outlined. Undertaking such a move ultimately differentiates the winners (those companies who view the market changes as opportunities) and the losers (those who feel threatened and carry on regardless).

  • Volume 70 Issue 1 - Increasing bearing service life in rope sheave
           applications
    • Abstract: Philippe, Gachet
      Both paper mills and SKF focus heavily on the main bearing applications such as press rolls, suctions rolls and heated cylinders. These are critical applications where maintenance is often time-consuming and costly.

      In contrast, other bearing applications like rope sheaves are sometimes considered to be of rather low importance because spare parts are comparatively cheap and can be replaced easily. Nevertheless, incidents can happen that put these applications firmly on the maintenance staff and mill management agenda.

      This happened in 2001 when Stora Enso Kvarnsveden approached SKF in Sweden about a problem they had experienced with a rope sheave in the dryer section. A bearing failure on it led to the sheave dropping six metres and narrowly missing one of the mill staff.

      SKF studied the sheave design and concluded that bearing service life could be dramatically increased using existing technology and knowledge.

  • Volume 70 Issue 1 - Influences of the characteristics of printing inks on
           the effects of blister packaging
    • Abstract: He, Zhiheng; Chen, Gang; Wang, Qinwen; Chen, Chen
      In terms of the characteristics of printing inks, this study investigated the influences of the viscosity and drying rate of printing inks on the picking velocity of paper and the ultimate effects of blister packaging. Experimental results showed that both the viscosity and drying rate of printing inks exerted great influences on the picking velocity of paper and the peeling strength on blister packaging. When the viscosity of printing inks was decreased, the picking velocity of the paper increased, while the peeling strength was gradually increased. When printing inks were dried more quickly, the picking velocity of the paper was decreased and the peeling strength required for blister packaging was gradually weakened. In addition, the picking velocity of paper presented a good linear correlation to its peeling strength required for blister packaging with the correlation coefficient reaching over 0.966. Therefore, while producing paper for blister packaging, high-quality blister packaging materials can be acquired by adjusting the picking velocity of the paper.

  • Volume 70 Issue 1 - Conditions of relative humidity and temperature for
           paper testing in Australia
    • Abstract: Nadebaum, OO
      The properties of paper are sensitive to moisture content. This, in turn, depends on the relative humidity of the surrounding atmosphere and the paper's moisture history. For these reasons quality control testing of paper has been carried out in controlled atmospheric conditions. Australia and New Zealand through Appita's involvement with the testing standards committees of the world, to this day with ISO Technical Committee TC 6, have always played a major role in setting these standards.

           interactions in recycled paper
    • Abstract: Bildik, Ahsen Ezel; Hubbe, Martin A; Gurboy, KBahattin
      Alkylketene dimer (AKD) sizing dispersions from two commercial sources, in addition to the corresponding laboratory-produced AKD dispersions, were investigated relative to their usage in a recycled office waste furnish Two main sets of experiments were carried out. One set involved testing the pulp after AKD treatment, with the evaluation of dewatering rates, retention efficiency, and charge. The other set involved brightness and water resistance properties when AKD was added in making handsheets. There was generally a positive but decreasing incremental effect of the sizing treatments (dispersions or associated cationic polyelectrolytes) with increased levels of addition, on drainage rate and retention efficiency. AKD treatment resulted in increased brightness, which was attributed to increased retention of calcium carbonate and of fluorescent whitening agent in the paper. Less sizing agent was required in the recycled furnish compared to the virgin fibre. Results were consistent with the charged character of the emulsified AKD formulations.

    • Abstract: Micic, Vlad
      In order to increase machine speed while maintaining paper strength, Visy Paper 2, in Melbourne Australia, commissioned a wet-end table upgrade to achieve improved formation and drainage control. Before the table upgrade, Visy Paper 2 had limited stock activity on the bottom wire, resulting in less than optimal turbulence to assist in drainage as well as formation. To compensate, machine speed and formation was mostly governed by the addition of drainage/retention aid chemicals. The doses of drainage aid required to achieve desired speeds appeared to negatively impact paper strengths.

  • Volume 69 Issue 3 - China import crash shows fragility of domestic market
    • Abstract: Woods, Tim
      Imports of paper and paperboard from China have played a significant role in Australia, over much of the last decade. That is why a recent crash in the value of imports to Australia from China has been so important. It would be tempting to view this as due to the slowdown in China and the change in its direction, but the reality is more complex. With the value of imports falling for most major grades of paper and board, the uncomfortable reality is that Australia's demand appears to have declined. Latest analysis and industry commentary suggests this may be a major correction, with many warehouses over-stocked for some months.

  • Volume 69 Issue 3 - Selecting the markets for bio-fuels
    • Abstract: Covey, Geoff
      Reserves of petroleum will last for at least another twenty-five to fifty years. Therefore drop-in liquid biofuels need only serve a short-term market while new engines are developed which can effectively use bio-fuels which have been less extensively modified and are therefore cheaper and made with greater energy efficiency.

      It is also argued that the emphasis should be on initially entering the market segments where the technical and regulatory requirements for the fuels are easily satisfied. Therefore marine and road transport applications are better targets than aviation fuels for market entry.

      It is shown that there have been many examples where one fuel type has been replaced by another which was not compatible with existing combustion equipment, and that the change-over time from the old fuel to the new is typically ten to fifteen years - in which time existing engines are replaced with types designed for the new fuels.

           production efficiency
    • Abstract: Lowe, Rob; Duffy, Brian; Benz, Brad
      The strength of paper has always been a critical sheet parameter; however, it is rarely the ultimate driver for the use of dry strength additives. Often, dry strength additives are used as a tool to balance negative impacts that can come from attempts to lower the total cost of operation. The desire to improve production rates while also reducing raw material costs is driving a growing trend towards lighter basis weights and the increased use of recycled furnishes. This paper examines multifunctional dry strength additives used to improve paper strength per unit of basis weight while lowering the total cost of operation in board and packaging grades.

  • Volume 69 Issue 3 - Evaluating and optimising dryer section performance
    • Abstract: Malton, Stan; O'Driscoll, Wayne
      The paper machine dryer section consumes large amounts of steam energy. It also has a significant impact on both production and sheet quality. As a result, mill profitability can be heavily influenced by overall dryer performance.

      The drying process, like other papermaking operations, is a complex matrix of interacting components: pocket ventilation, steam distribution and handling, drive system, tail threading, sheet handling, energy recovery, and fabric conditioning, guiding, and tensioning. An evaluation of the dryer section begins with identifying the performance criteria and standards of good dryer section operation. Once defined, a complete set of dryer section measurements, including an analysis of equipment sizing, is performed to assess performance against the defined standards. In this paper recommendations are provided for operational improvements, equipment upgrades, and a checklist of short-term and long-term improvement projects prioritised by the expected economic return. Typical returns come from energy savings, increased drying capacity, reliable dryer drainage, improved dryer section runnability, and enhanced drying uniformity, among other improvements. A comprehensive dryer performance evaluation report identifies improvement opportunities and quantifies the associated benefits.

      This paper discusses the benchmarks commonly used when evaluating dryer section performance. Common opportunities for steam efficiency improvements are identified.

  • Volume 69 Issue 3 - Decomposition of hydrogen peroxide by manganese in the
           presence of lignin
    • Abstract: Zhang, Xuejin; Wang, Lijun; Li, Youming; Lei, Lirong
      In this study, the effects of both free manganese ions and manganese in the presence of precipitated lignin on the decomposition of hydrogen peroxide under typical pulp bleaching conditions were investigated. Precipitated lignin was generated by hydrochloric acid, without further purification, and reacted with a Mn solution before testing its effect on peroxide decomposition. A variety of bleaching stabilizers, ethylenediaminetetraacetic acid (EDTA), sodium silicate (Na2SiO3) and magnesium sulfate (MgSO4), were added individually or in combination, to investigate their effects in controlling the free manganese induced or precipitated lignin-combined manganese induced hydrogen peroxide decomposition. Fourier Transform Infrared Spectroscopy (FT-IR), Elemental Analyses, Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES), were used to study the chemical features of the precipitated lignin-manganese composites, as well as the amount of metal ions presented in the solution or adsorbed on precipitated lignin.

      The results showed that the hydrogen peroxide decomposition in the presence of both free manganese and precipitated lignin-combined manganese can be represented by a pseudo-first-order kinetics. The decomposition of hydrogen peroxide by free manganese ion under alkaline condition was significantly greater than when precipitated lignin was present, with pseudo-first-order rate constants of 2.89*10-2 min-1 and 6.53 *10-4 min-1 respectively. EDTA added individually showed the most positive effect on further reducing the decomposition of peroxide in both cases, dropping the pseudo-first-order rate constant (kobs) to 2.57*10-4 min-1 in the case of free manganese, and to 3.44 *10-4 min-1 in the presence of lignin-combined manganese.

      Analysis showed that only a small amount of Mn in solution is complexed by the lignin so a significant amount of free Mn is still present after complexation. Hence it is not clear whether the complexed Mn is the critical factor in this lignin effect or whether the lignin itself is acting as a peroxide stabilizer.

    • Abstract: Magnusson, Hans; Kvarnlof, Niklas; Henriksson, Gunnar; Germgard, Ulf
      This work investigates the potential to integrate prehydrolysis kraft pulping with modern viscose manufacturing in order to improve the economic and environmental feasibility of the two processes. The study is largely based on calculations from previously reported data and information obtained from earlier employees of the Svenska Rayon viscose mill of Karlstad, Sweden, but key stages are also tested experimentally. It is concluded that integration of these two processes gives several benefits: the pulp mill can produce the alkali needed for mercerization and dissolution; the chemical recovery system of the kraft mill can take care of the spent liquors from the viscose plant; green liquor from the pulp mill can be used for the recovery of zinc from the spent coagulation liquor; the kraft pulp mill can produce sulfuric acid for the spinning bath of the viscose plant; and energy can be saved since drying of the pulp that would go into the viscose mill is not needed.

    • Abstract: Singh, Sonita; Stack, Karen R; Lewis, Trevor W; Richardson, Desmond E
      A laboratory scale froth flotation batch process has been optimised for removal of wood extractives from Pinus radiata thermo-mechanical pulp (TMP) process water. This has provided insight into the mechanism of flotation and has potential for application in industry. The study involved optimisation of surfactant type and concentration, flotation time, airflow, impeller speed, pH, temperature and ionic strength.

      Maximum wood extractive removal was achieved by flotation with the addition of 80 mg/L of the cationic surfactant dodecyltrimethylammonium bromide (DoTAB) at pH 5.0 and 60 degreesC for 20 min with an air flow of 4.5 L/min and impeller speed of 1300 rpm. Under these conditions the removal efficiency of total extractives was close to 95%. Process water treated in this way would be suitable for recirculation in a pulp or paper mill and would result in significant reduction in problems caused by accumulation of wood extractives.

  • Volume 69 Issue 2 - Interstage fractionation and low consistency refining
           for TMP. Part 2: Fibre development
    • Abstract: Lemrini, My-Mustapha; Lanouette, Robert; Michaud, Gaston
      The primary aim was to study a variation in TMP manufacture, in which an interstage fractionation followed by low consistency refining (LCR) and high consistency refining (HCR) in series for different percentage of LCR, is applied to the long fibre fraction. Both consistency of refining and fractionation (together with refining of the LF fraction) lead to important differences in terms of fibre development. The decreases in coarseness alone cannot explain the bonding improvement observed. As little delaminated surface is believed to be available, this observation suggests that observed improvements in the tensile index, are most probably due to the changes in the microstructure of the fibre itself (such as cracks in the wall or internal delamination). These microstructure changes increase fibre flexibility and therefore develop the bonding area.

  • Volume 69 Issue 2 - Sampling, analysis and the determination of the source
           of contaminants causing hickeys on newsprint
    • Abstract: Heier, Deanne; Parsons, Tony; Grubb, Meegan
      A major customer of Norske Skog (the Customer) had a severe outbreak of hickeys at one of their pressrooms (Site A) which became a significant issue in April 2013. Initially, newsprint from the Albury Mill (NSW, Australia) was the primary focus of the investigation, as contaminants from the recycled fibre (RCF) process have been known to cause hickeys in the past. Process changes at the Mill around that period were investigated while extensive sampling and analysis was carried out to attempt to understand the issue.

      Samples of material causing the hickeys as well as reference material from the Mill and pressrooms were analysed by Fourier Transform Infrared (FTIR) spectroscopy. The sampling encompassed other Customer pressrooms as well as Site A to determine the extent of the issue. Intensive sampling led to a clear result, that there were three major types of material causing the hickeys. These were solidified ink particles, pieces of polytetrafluoroethylene (PTFE or Teflon) and a 'plastic-like' material that could not be identified.

      The 'plastic-like' material did not match to any known spectra in the internal or external FTIR databases that Norske Skog utilises. The same three contaminants were found at other Customer pressrooms to a lesser extent, such as Site B, which consumes paper from the Boyer Mill (TAS, Australia), and Site C, during a trial of paper from the Tasman Mill (New Zealand). The paper from these two mills does not have RCF content. None of the three contaminants had been found in the paper and other customers were not experiencing the same issues. Focus shifted to the ink and an ink filter was installed at Site B on the cyan inlet to the printing press. In September 2014, it was confirmed that all of the three major contaminants were present in the ink line. Further targeted sampling at Site A uncovered large pieces of the same three types of contaminants present in the ink screens at the first point the ink reaches the site.

      After the removal of the contaminants from the ink screens at Site A, the levels of hickeys reduced significantly, to the point that they were no longer considered a commercial issue. Site A now ensures that ink screens and filters are cleaned during routine maintenance activities.

      Australia is becoming increasingly reliant on plantations to meet its forest resource demands, with softwood and hardwood plantations providing more than 80% of the fibre needs of our wood and paper product industries. Yet, while our reliance on wood fibre from plantations grows, the plantation estate is shrinking. In the past eight years there has been very little investment in new plantation establishment. Over the same period, we have seen a rationalisation of the plantation resource, with plantations previously established on poor quality sites or too far from markets being harvested and not replanted.

This event, perhaps not immediately, but eventually, will result in further sector consolidation, new manufacturing investment and supply chain rationalisation, especially as GPI will pursue what it describes as its 'growth ambitions' in Australia and New Zealand.

  • Volume 69 Issue 2 - A bright future for pulp bleaching: Highlights from
           the 2014 International Pulp Bleaching Conference
    • Abstract: Johnson, Tony
      The bleaching of pulp is a core business in the production of pulp and bleached pulp is a commodity traded around the globe. Globally, there are over 400 individual bleaching lines processing kraft, sulphite, mechanical and deinked pulps. The major forum for the presentation and exchange of technical bleaching information is the International Pulp Bleaching Conference (IPBC) held every three years. The IPBC is dedicated to all chemical and process aspects of chemical pulp bleaching and the presentations are selected by the conference scientific committee, which is composed of renowned international experts in bleaching. The most recent IPBC was held from 29th - 31st October, 2014 in Grenoble, France and focused on the newest developments and research advances in bleaching.

  • Volume 69 Issue 2 - The influence of blister varnish and printing
           parameters on blister peel strength
    • Abstract: Ji, Xiaoting; Wang, Qinwen; Fu, Shiyu
      This paper focused on the influence of different blister varnishes and printing parameters, including the kind and amount of diluent, the dot area coverage, and the ink thickness, on the peel strength in blister packaging. A method was developed using Confocal Laser Scanning Microscopy to quantitatively represent the penetration depth of blister varnish. With increasing ink thickness, the penetration depth of blister varnish and hence the peel strength decreased. In addition, clear differences relating to the dot area coverage were detected, and the full point printing sample was found to produce the worst results overall. The amount of diluent also had an influence on the penetration depth of blister varnish and, therefore, the peel strength.

  • Volume 69 Issue 2 - Value added data analytics using historical pulp and
           paper process data
    • Abstract: O'Connor, Matthew
      Pulp and paper manufacture involves the use of many unit processes to convert raw fibre sources into a finished product. Due to inherent variability in feed-stocks and process inputs, the properties of the finished paper product can vary, both below quality targets - causing issues with production and downstream use - or above quality targets, incurring unnecessary costs and product variability. In recent years, data historians have been introduced to many pulp and paper mills to record process variables, sometimes in the thousands for a site, and often with high frequency resolutions. This data is useful to see how a specific variable has varied in the past and to help identify causes for process variability or upsets. However, this large amount of data also presents an opportunity to gain an advanced understanding of the process through modern data analytics. This paper reviews several data analytics methods available to exploit this data to better understand and control the process.

      A sample data set from a deinking line was used to explore several data analytics methods with the application of predicting deinking performance from flotation cell operation. Initially the data was collected and preprocessing was applied, first with manual filtering and time delays and then with more advanced frequency filters. Simple univariate methods and hypothesis testing were the first stage of data analysis. Regression methods were explored including Partial Least Squares (PLS) regression which was used to identify underlying latent variables in the data. Hotelling's T2 statistic was then used to identify when the process was out of control from a baseline and what variables were responsible. Finally, the applications of using online data analysis for real time process trouble shooting was explored.

      It was found that regression methods were mildly useful to predict deinking performance from flotation cell operation but were difficult to link the model back to process variables. Hotelling T2 was good at seeing real changes in relationships between variables, however this relied on appropriate selection of baseline data. All methods required an understanding of the process - both practical and theoretical - when selecting variables to analyse for a particular problem and interpreting outputs of data analytic methods to make useful decisions.

  • Volume 69 Issue 2 - Study on the interactions between dissolved and
           colloidal substances under the treatment of fixing agents in papermaking
    • Abstract: Wang, Lijun; Zhang, Yiqian; Zhang, Xuejin; Fatehi, Pedram
      Fixing agents, highly cationic and low molecular weighted polyelectrolytes, are widely used in the papermaking industry to attach dissolved and colloidal substances (DCS) to wood fibres and remove them from papermaking systems. However, the interaction between the fixing agents and DCS is still not well understood. In this study, oxidized starch, resin acid, and mixes thereof were used as models for dissolved substances (DS), colloidal substances (CS), and dissolved and colloidal substances (DCS) in simulated papermaking furnishes, respectively. These were treated with three different polyamine fixing agents (PA) and their effect on the stability of the systems was evaluated by analyzing the residual concentrations of the model compounds after solid-liquid separation. The interactions between the dissolved substances and the colloidal substances were inferred from the results. The effectiveness of the fixing agents in removing the oxidized starch was poor while their effectiveness in removing the resin acid was good in the singular systems. However, in the mixed DCS system, the removal of the oxidized starch was improved, while that of the resin acid was worsened. The results indicate that when a fixing agent is added into the mixed DCS system, the DS is first changed into DS-polyelectrolyte complexes (PEC), and the PEC is attached to the CS particle surfaces, improving the stability of the latter and making it more difficult to remove. On the other hand, once the CS stability is disturbed and its agglomeration takes place, more DS can be removed compared to the singular DS system.

  • Volume 69 Issue 2 - Effect of nanofibrillated cellulose to reduce linting
           on high filler-loaded recycled papers
    • Abstract: Balea, Ana; Blanco, Angeles; Merayo, Noemi; Negro, Carlos
      The removal of particles from the paper surface and its accumulation on the printing blanket, or linting, is one of the most recurrent problems encountered in newsprint printing, and is aggravated in high filler-loaded recycled papers. Nanofibrillated cellulose (NFC) is currently receiving a great deal of attention due to its enormous potential as a reinforcement aid in high filler-loaded papers through increased filler-fibre interaction and interfibre bonding. The effect of NFC addition on linting however has not yet been investigated. The objective of this research is to quantify the effect of NFC on linting in newsprint. Different concentrations of PCC and NFC were added to a recycled paper pulp that contained 14% by wt. ash, and the efficacy of NFC as a linting control agent was evaluated. A NFC dose of 1.5% by wt. in recycled paper reduced linting by as much as 47%; moreover, retention and drainage were improved.

    • Abstract: Istikowati, Wiwin Tyas; Aiso, Haruna; Ishiguri, Futoshi; Sutiya, Budi; Ohshima, Jyunichi; Iizuka, Kazuya; Yokota, Shinso
      The anatomical characteristics of terap ('Artocarpus elasticus'), medang ('Neolitsea latifolia') and balik angin ('Alphitonia excelsa') were studied to identify new pulpwood resources among lesser-known species native to Indonesia. The mean values of fibre and vessel element lengths were 1.55 and 0.42 mm in terap, 1.21 and 0.56 mm in medang and 1.14 and 0.52 mm in balik angin. The mean proportions of vessel, fibre, ray parenchyma, axial parenchyma and cell wall were 10.5%, 48.5%, 18.3%, 22.7% and 45.4% in terap, 21.6%, 49.7%, 13.8%, 14.9% and 50.5% in medang and 15.6%, 67.7%, 10.3%, 6.4% and 46.4% in balik angin. The anatomical characteristics of the three species were similar to those of fast-growing tree species used as pulpwood. Fibre diameter and cell wall percentage were significantly correlated with basic density in all species, indicating that diameter of wood fibre and cell wall percentages affect basic density values of all three woods.

  • Volume 69 Issue 1 - Interstage fractionation and low consistency refining
           for TMP. Part 1: Energy consumption and pulp properties
    • Abstract: Lemrini, My-Mustapha; Lanouette, Robert; Michaud, Gaston
      The impact of an interstage fractionation followed by a low consistency refining (LCR) stage prior to a high consistency refining (HCR) was studied. We present the resulting energy consumption and pulp property changes when different energy input ratios (energy at LCR/energy at HCR) are applied to the long fibre fraction obtained at the interstage screening.

      Three basic processes were studied: (1) a high consistency (HC) refining, (2) a low consistency (LC) refining, and (3) fractionation followed by an LCR stage and an HCR stage in series applied to the long fibre fraction, and recombination. We applied different energy levels to the long fibre fraction, from 100% of the secondary stage refining energy at LC and 0% at HC to 0% applied at LC and 100% at HC, as well as three intermediate ratios of the energy applied at LC. Properties were altered when excessive energy was transferred to the LCR. Adjustment of the LCR/HCR ratio prevented large losses in terms of tensile and tear strength. For 17 to 29% energy savings (to reach 100 CSF), the loss in tensile increased from 6 to 9%, whereas the tear changed insignificantly. Fractionation is significant in altering the energy-pulp property relationship, except in the case of tensile strength. Overall these results demonstrate that there is a considerable range of options for reducing the energy input while maintaining the quality of the final pulp through the use of fractionation and a combination of low and high consistency processes.

  • Volume 69 Issue 1 - Weighted averages and distributions of fibre
           characteristics of mechanical pulps Part II: Distributions of measured and
           predicted fibre characteristics using raw data from an optical fibre
           analyser
    • Abstract: Osterling, SReyier; Ferritsius, O; Ferritsius, R; Johansson, CA; Stangmyr, J
      Characterisation of fibres in mechanical pulps is important for process evaluation and control, and necessary to be able to optimise the refining process with respect to the total electric energy consumption. There are large variations of cross-sectional fibre characteristics in the wood raw material which influence the properties of the product. Despite this, it is common to evaluate the fibre characteristics as averages instead of distributions. This study shows that the raw data from a FiberLab analyser can be used to make distributions of measured and predicted fibre characteristics. The factor BIN (Bonding ability INfluence), which correlates to long fibre tensile index, includes both the external fibrillation and wall thickness of each fibre. Distributions of BIN, fibrillation and wall thickness which take the characteristics of each fibre into consideration have higher resolution than histograms. These distributions weighted by length and wall volume with maintained resolution revealed more information about the pulps than average values.

  • Volume 69 Issue 1 - Optical brightening agent quenching effect in furnish
           containing high-yield pulp
    • Abstract: Liu, Hongbin; Li, Chuanyou; Wang, Lijuan; Peng, Jinyong; Chen, Cui
      The use of optical brightening agent (OBA) and High-yield Pulp (HYP) in fine paper production is driven by enhanced brightness requirements and reduced manufacturing cost. Due to the fact that HYP contains high amount of lignin, the OBA quenching effect, defined as the decrease in the OBA brightening efficiency due to the presence of lignin in the HYP-containing furnish is a concern. The OBA brightening in pulp furnish containing HYP, together with wet end chemicals (PEI, CPAM, APAM, cationic starch) and fillers (PCC or GCC), were investigated. It was found that the OBA brightening efficiency decreased with increased HYP content in the furnish. Polyethylenimine (PEI) had the most noticeable negative effect on the OBA brightening efficiency. PCC filler produced greater brightness gain than GCC filler at the same OBA dosage.

  • Volume 69 Issue 1 - Integration of electrolysis to produce hydrogen and
           oxygen in a pulp mill process
    • Abstract: Kuparinen, Katja; Vakkilainen, Esa; Ryder, Peter
      The pulp and paper industry faces demand for totally carbon free production. Due to local conditions, there are challenges to sell produced additional electricity. A novel way, generating hydrogen and oxygen through the electrolysis of water can decarbonize the largest fossil carbon dioxide producing equipment, the lime kiln. The oxygen produced can be used for generation of bleaching chemicals, and also for effluent treatment. The operation and capacity of the recovery boiler can be improved by oxygen use. Using excess electricity of a typical, large South-American pulp mill, 73% of the heat demand of the lime kiln can be covered with hydrogen and the produced amount of oxygen exceeds the mill's oxygen requirement. The profitability of the integration depends on the other possible uses for electricity. When sales price for electricity is low or purchased oil price is high electrolysis can decrease the operating costs of a modern pulp mill.

  • Volume 69 Issue 1 - How sonic ZD measurements can optimise the paper
           machine
    • Abstract: Allan, RJ
      In-plane sonic measurements have been used for many years to determine fibre orientation and more recently to predict some traditional paper properties like ring crush, SCT and burst. Due to the complexity of the measurement, zd sonic stiffness measurements have not been introduced as a main stream measurement within the paper industry. Despite this, the measurement is a valuable adjunct to the usual paper laboratory testing. Because of the zd sonic test's strong relationship with bonding in the paper sheet it can be used to sensitively reflect paper machine treatments or processes that develop or hinder paper property development. The measurement is useful in identifying issues with and optimising paper machine processes like forming, pressing, starch, calendering and draw settings. This paper describes how the measurement has been used to gather information on the paper machine regarding process effects on paper performance. In many cases the technique delivers insights into paper performance that are not available from traditional testing.

  • Volume 69 Issue 1 - M3 WIS replacement project: Practical experiences
           using Procemex Twin system
    • Abstract: Ryan, Kevin; McNamara, Chris
      Maryvale M3 is an 80,000 tonne per annum fine paper machine producing mainly uncoated wood free copy and printing grades. In June/July 2012, M3 experienced a sudden increase in the number of customer's complaints about starch debris in the sheet.

      Immediate actions were taken to resolve/mitigate the issue but one particular concern was that starch debris reported by the customers had not been detected or recorded by the Web Inspection System (WIS) at the time of manufacture and going forward, would most likely fail to report any possible re-occurrence. Testing confirmed that the WIS was not detecting the starch related debris. This situation was unacceptable and a solution was required.

      The M3 Measurex system installed in 1998 was obsolete, leaving little option but to replace the WIS system.

      Samples of starch debris were provided to a number of potential suppliers of Web Inspection systems. All the WIS suppliers were able to detect the presence of the defects in the paper but it was immediately obvious that images taken of the starch deposits were highly variable; some were dark like dirt while others were almost transparent. This meant that detecting the defect would be easy; but classifying the defect correctly would be very difficult.

    • Abstract: Wilks, Rohan
      Plant surveys and process modelling have been undertaken to characterise the wastewater system at Australian Paper Maryvale. A biological survey has been undertaken to understand the underlying biology and a model has been developed to track key nutrients throughout the process. The model includes the transfer of components between the dissolved liquid phase and the solid phase. The model includes clarifier separation efficiency, aerobic generation of biomass and transfer of nutrients between sediments and the active part of the process.

      The process model has been developed through sampling and analysis of liquid phase and solid phase components for each parameter. The model enables assessment of EPA licence compliance under different operating conditions, and provides a reference to identify changes in the underlying biology.
