  • TG analysis and kinetic study of organic constituents in wastewater from
           coal-gasification process
    • Authors: Wei Zhang; Chang'an Wang, Guangyu Li, Yinhe Liu, Defu Che
      Abstract: In the paper, the thermal reactivity of organic constituents from coal-gasification wastewater is performed through physicochemical and thermogravimetric (TG) analysis. The effects of reaction atmosphere, oxygen concentration, heating rate, and final temperature on both solids conversion and degradation rate are experimentally studied. The results indicate that organic constituents mainly consist of aliphatic hydrocarbon, phenols, and ammonium, and so on. The thermal degradation of organic constituents in various atmospheres can be divided into four regions: 100–200, 200–300, 300–410, and 410–900 °C. The TG/DTG curves present considerable differences in the last region compared with that in the first three regions. In addition, the degradation rate shows a considerable increase and moves toward higher temperature region with heating rate. Furthermore, the kinetic parameters of organic constituents are analyzed by one multi-heating rate method. The calculated results show that apparent activation energy of organic constituents varies between 82.8 and 91.3 kJ mol−1 under various reaction atmospheres. This information is potentially useful for the design and retrofitting of the large-scale equipment to recover industrial wastewater. © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Hydrogenation of tar residue derived from the synthesis of rubber
           vulcanization accelerator 2-mercaptobenzothiazole
    • Authors: Jianhong Zhao; Xianglin Cheng, Liucheng Wang, Jianshe Wang, Chengying Song
      Abstract: A large amount of hazardous tar residue is produced during the synthesis of rubber vulcanization accelerator 2-mercaptobenzothiazole (MBT). In this study, pyrite (FeS2) was used as catalyst for the hydrogenation of the tar residue under different conditions. Optimal hydrogenation conditions were as follows: 270 °C under an H2 pressure of 4.5 MPa for 8 h under a catalyst loading of 2%. MBT presented in tar residue is converted to benzothiazole (BT) by a high yielding hydrogenation in 86.9% yield based on the initial amount of BT with a small quantity aniline also produced as side product. This work provides a framework for possible ways to treat the toxic tar residue formed in the industrial synthesis of BT through the hydrogenation procedure established in this study. © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Experimental study of permeability reduction and pore size distribution
           change due to asphaltene deposition during CO2 huff and puff injection in
           Eagle Ford shale
    • Authors: Z. Shen; J.J. Sheng
      Abstract: Many laboratory and simulation studies regarding gas injection enhanced oil recovery method in shale reservoir have been performed and shown good results. However, one problem not investigated is the asphaltene precipitation and deposition problem. In conventional reservoirs, the permeability reduction caused by asphaltene plugging and adsorption has been observed and well studied. In shale reservoirs, the deposition, if any, will be more critical.In this work, experimental studies were conducted to investigate the effect of asphaltene deposition on the pore size reduction and permeability reduction in shale core samples during the CO2 huff and puff injection process using a dead oil sample from a Wolfcamp shale reservoir. A decrement of pore with a diameter size in the range from 100 to 800 nm and an increment of pore with a diameter size smaller than 100 nm were observed after 6 cycles of CO2 huff and puff injection. The result indicates the existence of pore plugging and asphaltene adsorption during the gas injection process. The experimental results also showed a 47.5-nD permeability reduction after 6 cycles of CO2 huff and puff injection. Compared with the original permeability of the shale core, 126 nD, the permeability reduction is more than one-third of the original permeability. © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Decomposition characteristics of compound additive and effect of roasting
           atmosphere on vanadium extraction from stone coal
    • Authors: Yunliang Zhao; Shichang Kang, Wei Wang, Yimin Zhang, Shaoxian Song, Shenxu Bao
      Abstract: In this work, the decomposition characteristics of compound additive (NaCl and Na2SO4) were investigated by thermogravimetry–differential scanning calorimetry–mass spectrometry coupling techniques. The results showed that the decomposition of NaCl was prior to that of Na2SO4 and the chlorine was generated during roasting. When the chlorine concentration is more than 2%, the phenomenon of vanadium volatilization becomes obvious in the process of roasting of stone coal. However, the chlorine concentration is less than 50 p.p.m. for the compound additive roasting, which would not cause the vanadium emission. The oxygen concentration of more than 5% is sufficient for oxidizing V(III) in the stone coal to water soluble V(V). Copyright © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Parametric investigation of polymethacrylate monolith synthesis and
           stability via thermogravimetric characterisation
    • Authors: Caleb Acquah; Michael K. Danquah, Charles K. S. Moy, Mahmood Anwar, Clarence M. Ongkudon
      Abstract: Polymethacrylate monoliths are synthetic adsorbents with macroporous and mesoporous interconnected channels that can be engineered to target the hydrodynamic features of a wide range of molecular species. However, rigorous study into the effect of synthesis conditions on their thermal stability is limited. This work attempts to characterise the influence of key synthesis process variables on the stability of polymethacrylate monoliths using thermogravimetric analysis at a heating rate of 10 °C/min. Experimental results showed that the thermal stability of polymethacrylate monoliths increased with decreasing polymerisation temperature from 85 to 65 °C. Increasing the total porogen (P) to monomer (M) ratio increased the thermal stability of the monolith by >62% and >50% for P40/M60–P60/M40 and P60/M40–P80/M20, respectively. The impact of the initiator concentration, monomer variation, biporogen ratio, washing and activation of the monoliths was investigated. Nuclear magnetic resonance analyses conducted confirmed the hydrolysis of epoxy moieties on the monolith. © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Sulfation roasting characteristics of copper-bearing materials
    • Authors: M. Ozer; E. Acma, G. Atesok
      Abstract: In this study, the sulfation roasting characteristics of copper-bearing ore and its flotation products as chalcopyrite concentrate and tailings were investigated in detail. For this aim, the roasting-leaching experiments and thermal analyses were conducted on the samples. As a result of the leaching of sulfated products obtained from the roasting experiments, the maximum Cu extractions were achieved as 94.7%, 99.5% and 82.7%, for run of mine, chalcopyrite concentrate and the flotation tailings, at the roasting temperatures of 550, 650 and 525 °C, respectively. It was also found that the copper extractions began to decrease owing to decomposition of copper sulfates above these temperatures. It was indicated that the decomposition temperature of copper sulfates differ for each samples. On the other hand, thermal gravimetric and differential thermal analyses were subjected to identify the thermal behaviors of the samples. The results showed that the formation of metal sulfates occurred in a wide temperature range (394–650 °C) for chalcopyrite. On the contrary, copper sulfation reactions took place at narrow temperature ranges of 450–560 °C and 480–550 °C for the run of mine ore and the flotation tailing, respectively. © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Trade Effects of US Antidumping Actions against China*
    • Authors: Minsoo Lee; Donghyun Park, Antonio Saravia
      Pages: 3 - 16
      Abstract: Using data on US imports, classified at the 10-digit Harmonized System commodity level, we study the effects of all antidumping investigations initiated by the USA against China between 1998 and 2006. We find that antidumping actions cause a reduction in the volume and value of imports from China as well as an increase in the price of those goods in the US market. Critically, however, we find that these effects are short-lived and dissipate approximately 2 years after the antidumping decision. Furthermore, antidumping actions against China prompt a substitution effect as they increase US imports from other countries. In general, our results cast doubt on the effectiveness of antidumping actions against China as mechanisms for protecting US producers.

  • Impact of Monetary Supply on Chinese Nonferrous Metal Price Movement*
    • Authors: Zesheng Sun; Bianxia Sun
      Pages: 17 - 37
      Abstract: Employing both classical vector autoregressive methodology and regression models utilizing shock factors constructed with the Hodrick–Prescott filtering method, this paper empirically studies the influence of monetary factors on the price of nonferrous metals and their expectation formation in the Chinese market. Monetary factors are found to significantly positively influence Chinese nonferrous metal prices, and further empirical research reveals that a structural change occurred near August 2006. There is an expectation formation mechanism of lagged futures prices on spot metal prices, and the risk originating primarily from international market is transmitted to Chinese markets.

  • House Price Dynamics with Household Debt: The Korean Case*
    • Authors: Hyun Jeong Kim; Jong Chil Son, Myung-Soo Yie
      Pages: 39 - 59
      Abstract: This paper revisits the long-run determinants of house prices, and analyzes the house price dynamics using Korean data taking into account the close relationship between house prices and household debt. The results of cointegrating regression indicate that the major portion of the rise in house prices in Korea over the last 15 years can be explained by changes in macro variables such as household income, the demographic structure, the user cost of home ownership and the housing stock supply. The results also confirm that house prices are, indeed, closely linked to the steep increase in household debt seen over this period. Estimation of an error correction model shows that the extent of convergence of actual house prices to their long-run equilibrium path has weakened somewhat since the global financial crisis while the speed of convergence has slowed, indicating structural changes in the Korean housing market. Finally, a forecast for house prices over the next several years suggests that they are unlikely to rise as sharply as they did in the 2000s, given the likely changes in the macro-financial environment, and that their future path will be closely associated with that of the household debt-to-income ratio.

  • Returns to Education Using a Sample of Twins: Evidence from Japan*
    • Authors: Makiko Nakamuro; Tomohiko Inui, Shinji Yamagata
      Pages: 61 - 81
      Abstract: The objective of this article is to measure the causal effect of education on earnings using a large dataset of twins compiled in Japan with wide-ranging socioeconomic information. Recent research conducted in China showed that, contrary to the case in Western countries, ability bias is large in estimating the return to education. It is argued that the low rate of return in China is in part due to the competitive and exam-oriented education system, which is similar to the system in Japan. The empirical results in our study show that the estimated rate of return to education using the sample of identical twins in Japan is 9.3 percent even after omitted ability bias and measurement errors in self-reported schooling were corrected. Our findings suggest that the conventional OLS estimate is not significantly contaminated by potential biases in Japan.

  • Rise and Fall of Multinational Enterprises in Vietnam: Survival Analysis
           Using Census Data during 2000–2011*
    • Authors: Tien Manh Vu; Hiroyuki Yamada, Tsunehiro Otsuki
      Pages: 83 - 109
      Abstract: This study examined the survival of multinational enterprises (MNE) in Vietnam during 2000–2011 using Cox hazard models. The characteristics and ownership structure of firms and the nationality of foreign partners are found to be associated with the probability of firm exit, with a firm having greater capital share of foreign partners surviving longer. An efficient local government requiring less time for bureaucratic procedures and inspections is found to be associated with a lower probability of MNE exiting. Meanwhile, transparency in business regulations and predictability in implementing central government policies accelerate the survival of highly competitive MNE.

  • Hydrodynamic simulation of a liquid–solid fluidized bed using Lattice
           Boltzmann and smoothed profile methods

      Abstract: In the present study, a combined Lattice Boltzmann method–smoothed profile method is used for simulation of a liquid–solid fluidized bed of circular, monodisperse, and polydisperse particles in a rectangular channel. The hydrodynamic model of the flow is based on the Bhatnagar–Gross–Krook Lattice Boltzmann method, and smoothed profile method is adopted to enforce the no-slip boundary condition at the liquid–solid interface and also calculate the fluid–solid hydrodynamic force. The kinematics and trajectory of the discrete particles are evaluated by Newton's law of motion. A numerical instance of fluidization involving 527 particles is presented to demonstrate the capability of the combined scheme. Comparison of minimum fluidization velocity and pressure drop through the bed with Ergun equation, and also porosity and bed height with the Richardson–Zaki equation, shows good correspondence. Several different models are also presented to investigate the influence of the density and polydispersity of particles in the fluidized bed. Simulations indicate that an increase in particle density decreases the porosity of the bed. Also, it is observed that the porosity of the polydisperse beds is less than that of monodisperse ones.

  • A simulation approach to achieve the best miscible enrichment in gas
           flooding and chemical injection process for enhanced oil recovery
    • Authors: F. Salari Sardari; M.R. Khorsand Movaghar
      Pages: 230 - 246
      Abstract: The effect of injected gas composition (as minimum miscible enrichment) on minimum miscibility pressure (MMP) and respective oil recovery has been studied through numerical slim tube simulation on a wide range of gas compositions. An initial comparative study on the performances of representative equations of state for predicting MMP in slim tube simulations has proven Peng–Robinson equation of state to provide results with better agreement with experimental data. Different injection scenarios are then designed to understand the effects of varying percentages of each component (like CO2) into the injected gas mixture on MMP. MMP decreased when the concentration of CO2 and intermediate components (C2–C6) increased. It was also found that when C7+ content in the injected gas increased, recovery factor decreased significantly. Further investigations on the effect of adding benzene, toluene, and xylene as chemicals into the injected gas (in slim tube simulations) also prove that addition of these aromatics can obviously improve oil recovery and decrease MMP and toluene gives the better results in comparison with the other ones. © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Control-oriented modeling of colloid transport by solute gradients in
           dead-end channels
    • Authors: Tehuan Chen; Chao Xu
      Pages: 247 - 258
      Abstract: When colloids are placed in the nonuniform solute concentration, they transfer toward or away from the higher solute concentration side. This phenomenon is called diffusiophoresis, which is widely founded in many solute–particle interaction processes. In this paper, we consider the colloid transport by solute gradients in dead-end channels with a boundary solute concentration being manipulated, which is a step-like concentration input. We model this process by a coupled solute–particle system, which involves the solute diffusion model and the colloid transport model, and establish a control-oriented model, which is important for controller strategy synthesis in practice. We use the method of separation of variables to obtain the analytical solution of the solute diffusion model and proposed an effective computational scheme for solving the colloid transport model. Thus, we give the simulation results of colloid transfer by considering different boundary solute concentration inputs and show the effectiveness and feasibility for more flexible external control. Finally, because the control-oriented modeling is a switching system governed by partial differential equations essentially, we reformulate the colloid transfer control problem and discuss this problem in detailed from the viewpoint of the computational optimal control.

  • Numerical simulations on effects of ionic / nonionic surfactant on
           oil-water interface using dissipative particle dynamics
    • Authors: S. Wang; J. Zhao, X. Li, S. Yang, X. Wang, Y. Liu, S. Yang, Q. Dong
      Pages: 268 - 282
      Abstract: Effects of surfactants on oil/water interface are studied using dissipative particle dynamics (DPD) at the mesoscopic scale. With a surfactant model, the effects of concentration of three types of surfactants, including ionic surfactant, nonionic surfactant, and the compound system of ionic and nonionic surfactant, on interfacial tension are analyzed in this study. Also, the distributions of interfacial tension and mean interfacial density are predicted. Simulated results indicate that the interfacial tension decreases with an increase of surfactant concentration. As the surfactant concentration increases to a certain value, the surfactant at the oil-water interface is saturated, and the interfacial tension will in-depend on surfactant concentration. It turns out to be that surfactants can be saturated just at the oil-water interface once its concentration reaches a certain value. A proper mixed ratio of compound system can reach a prime effect. Moreover, the inorganic salts can improve the interfacial efficiency of both ionic and nonionic surfactants, and lower interfacial tension. In addition, the temperature influences on surfactant aggregation behavior at the oil-water interface is discussed. Copyright © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Process development unit experimental studies of a split-flow modification
           for the post-combustion CO2 capture process

      Pages: 283 - 291
      Abstract: A process development unit (PDU) for amine-based post-combustion carbon capture located at Clean Coal Technologies Centre in Zabrze, Poland, was used to validate split-stream configuration. A PDU having capacity up to 100 m3n/h was designed to test the amine scrubbing carbon capture process from flue gases or mixtures of technical gases. Flexible process flow sheet of the unit allowed investigation of the split flow process.The split-flow flowsheet modification was compared with a standard system for chemical absorption-based CO2 capture. The tests were conducted using well-accepted baseline solvent: 30 wt% aqueous monoethanolamine solution. The flow sheet modification resulted in a decrease of reboiler heat duty by ~1.6% and an increase in CO2 recovery by ~1.2 p.p. Split-flow process modification was examined together with standard process flow sheet, and vast number of process parameters recorded during the trials have been presented. The explanation of beneficial effects of split-flow designs have been shown together with detailed analysis of experimental trials carried out using PDU for amine-based post-combustion carbon capture. This paper is also a valuable source of experimental data useful during validation of models. Copyright © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Validity of Egyptian Na-montmorillonite for adsorption of Pb2+, Cd2+ and
           Ni2+ under acidic conditions: characterization, isotherm, kinetics,
           thermodynamics and application study
    • Authors: A.A. Taha; M.A. Shreadah, Hany Fathy Heiba, A.M. Ahmed
      Pages: 292 - 306
      Abstract: This study investigated the applicability of natural Egyptian Na-montmorillonite (Na-MMT) to remove Pb2+, Cd2+ and Ni2+ under acidic conditions that mimic industrial wastewater acidity. Cation exchange capacity of Na-MMT was found 91 meq/100 g and the specific surface area 42 m2 g−1. The adsorbent was characterized using X-ray fluorescence, scanning electron micrograph that showed significant morphological changes after adsorption and Fourier transform infrared spectroscopy, which confirmed that the adsorption occurred mainly in the lattice region. Removal efficiency was evaluated as a function of pH, contact time, initial concentration, and adsorbent mass. Acidic pH value was chosen for the following experiments. Langmuir and Freundlich isotherm models were applied. Freundlich model showed better fitting suggesting heterogeneous adsorption scenario. Freundlich capacity values decreased in the order of Pb2+ (3.71 mg g−1) > Cd2+ (2.45 mg g−1) > Ni2+ (1.76 mg g−1). Kinetic data were accurately fitted to pseudo-second-order, indicating the adsorption occurrence in the interior surface of Na-MMT and the contribution of internal diffusion mechanism was significant. Intraparticle diffusion model gave multi-linear curves so more than one-step controlled the adsorption process. Under temperature range 290–328 K, thermodynamic parameters revealed that adsorption of Pb2+ and Cd2+ was spontaneous but Ni2+ non-spontaneous. Adsorption was exothermic for Pb2+ and Ni2+ but endothermic for Cd2+. Arrhenius activation energy values were 5.78, 8.51 and 11.45 kJ mol−1 for Pb2+, Cd2+ and Ni2+ respectively stating the physical adsorption. Na-MMT reusability was confirmed by regeneration experiments. Application study showed excellent efficiency of Na-MMT within range (23.4–81.2%) removal for Pb2+, Cd2+ and Ni2+ from textile dyeing and tannery wastewater.

  • Effects of microstructure design on aluminum surface hydrophobic and
           ice-retarding properties
    • Authors: K. Chen; T. Sun
      Pages: 307 - 312
      Abstract: The poor mechanical strength of superhydrophobic surface limits its use in civil aviation. In this work, superhydrophobic surfaces with open and closed microstructure design were prepared, and their hydrophobicity and icephobicity over icing/de-icing cycles were thoroughly studied. For all samples, contact angle decreased and contact angle hysteresis increased over time. However, surface with interconnected hollow honeycomb microstructure design kept its Cassie–Baxter state even after 20 times icing/de-icing cycles, while surface with repeated individual post microscopic unit lost its superhydrophobicity only after six times icing/de-icing cycles. The interconnected hollow honeycomb microstructure design strengthened surface mechanical strength by lowering the damage to microscopic unit. The freezing time for water droplet on surface with interconnected hollow honeycomb microstructure design was only slightly shortened over time. The difference in water/ice-solid contact area for surfaces with different nano-microscale design also led to the difference in wetting and ice-retarding ability. Surface with interconnected hollow honeycomb microstructure design showed the strongest ice-retarding ability followed by surface with interconnected hollow brick, ladder type, and triangle shape microstructure design. © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Ethaline and Glyceline binary eutectic mixtures: characteristics and
           intermolecular interactions
    • Authors: F.S. Mjalli; O.U. Ahmed
      Pages: 313 - 320
      Abstract: Deep eutectic solvents (DESs) are ionic liquids analogs that have been the subject of a growing interest in the scientific community. Governed by their favorable chemical and physical properties, they were utilized in a wide variety of fields. DESs possessing both desirable and undesirable properties for a specific application are not uncommon. As such, investigation into the variation of their properties upon mixing, in order to understand and improve their properties for a specific application, seems promising. In this study, the measurement of the physical and selected excess thermodynamic properties of Ethaline upon addition of Glyceline was carried out. The deviation of excess molar volume as a function of Glyceline molar fraction was observed to be alternating between negative and positive. This implies that the predominant interactions is due to either the difference in the sizes and shapes of the constituent molecules or to the effect dispersion forces. The highest deviations of the excess molar volume were observed at 30 and 90 mol% Glyceline. Density, viscosity, pH, RI and conductivity of the pure and DES mixtures were measured at different Glyceline molar fractions within the temperature range of 20 to 80 °C. © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Kaolinite induced control of particulate lead and cadmium emissions during
           fluidized bed waste incineration
    • Authors: Y. Huang; X. Wang, C. Liu, Y. Wang, L. Dong
      Pages: 321 - 331
      Abstract: Kaolinite was utilized as in-furnace sorbent to control submicron lead (Pb) and cadmium (Cd) emissions during waste incineration in a fluidized bed furnace. The secondary combustion chamber temperature ranged from 850 to 1000 °C. The metal capture was investigated for aspects of chemical reaction, physical conglutination and control performance of submicron metal emission. Pb reacted with kaolinite and caused conglutination of nanoscale metal particles at a lower temperature than Cd. Emission control of submicron Pb was far more effective than that of submicron Cd, particularly below 950 °C. For both Pb and Cd, there was capture limitation and an increase of kaolinite fraction above 3% could not further reduce the submicron metal emission. According to toxicity factors (5 Pb = 1 Cd) and the leaching fraction of submicron particles, the comprehensive performance of kaolinite was evaluated and numerous contradictory results were obtained. © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Optimum conventional extraction conditions for phenolics, flavonoids, and
           antioxidant capacity of Helicteres hirsuta Lour.

      Pages: 332 - 347
      Abstract: Helicteres hirsuta Lour. (H. hirsuta L.) has been used as a traditional medicine for treatment of various ailments such as malaria and diabetes in Southeast Asian countries. This study aimed to optimize the conventional extraction conditions for obtaining the highest levels of phenolics, flavonoids, and antioxidant activities within H. hirsuta L. using response surface methodology. The Box–Behnken design was employed to evaluate the effects of extraction time, temperature, and the sample-to-solvent ratio on bioactive compound yield and antioxidant capacity of H. hirsuta L. The results indicated that the sample-to-solvent ratio had the strongest impact on bioactive compounds and antioxidant power of H. hirsuta L. and revealed the optimum extraction conditions to include temperature of 60 °C, time of 35 min at the sample-to-solvent ratio of 1 : 100 g/mL using 40% (v/v) methanol as the solvent. Under these conditions, the highest levels of total phenolic content and total flavonoid content were 16.87 mg GAE/g and 17.55 mg CE/g, respectively, significantly higher than the values obtained using water as the solvent. When preparing powered crude extract from H. hirsuta L., the ratio of 3 : 100 (g/mL) was suggested for the saving of 67% of solvent volume and energy required for solvent removal, as similar total phenolic content and total flavonoid content yield (86–87%) as well as antioxidant activities were obtained in comparison with the ratio of 1 : 100 (g/mL). © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

  • Data-driven soft-sensor modelling for air cooler system pH values based on
           a fast search pruned-extreme learning machine
    • Authors: Yisha Ye; Jia Ren, Xuehua Wu, Guofu Ou, Haozhe Jin
      Pages: 186 - 195
      Abstract: Failures caused by acid erosion corrosion occur frequently in air cooler systems because of the use of increasingly low-quality crude oil with high sulfur, acid and chlorine content. The pH value is one of the key parameters used to evaluate the corrosion risk of an air cooler. However, this value is difficult to measure online because of the severe measurement environment, which includes high temperatures, high pressures and corrosion risks. In this paper, a pH soft-sensor modelling method for an air cooler system in a refinery production processing is developed. Using modelling and simulation in Aspen together with site data, the correlated influence factors are determined first. Then, a soft-sensor model based on a fast search pruned-extreme learning machine is proposed in which the pruning problem of hidden-layer nodes with random weights is solved by adopting the fast search density peak clustering algorithm. The proposed fast search pruned-extreme learning machine can improve the model's prediction performance by pruning redundant hidden layer nodes with a simpler structure. The feasibility and efficiency of the developed method are demonstrated by the results in the form of benchmark data and real air cooler system data.

  • Assessment of pre-treatment technologies for bioethanol production from
           sugarcane bagasse considering economics and environmental impact
    • Authors: J. Crimes; A.J. Isafiade, D.M. Fraser, M. Short, A. Bonomi
      Pages: 212 - 229
      Abstract: This work involves the assessment of various pre-treatment methods for the production of bioethanol in South Africa from sugarcane bagasse. The possibility of producing methane was also considered. The pre-treatment methods that have been modelled are acid pre-hydrolysis, steam explosion (acid-catalysed and un-catalysed), delignification with sodium hydroxide, acid hydrolysis and enzymatic hydrolysis. These pre-treatment options were arranged in a superstructure, and optimization was performed by decomposing the superstructure into eight possible flowsheets. These flowsheets were then optimized in General Algebraic Modelling Systems by using economic and environmental objective functions sequentially. The solution space was used to evaluate the possible flowsheets in terms of both objectives. Steam explosion pre-treatment would be recommended for the production of only methane. Acid hydrolysis can be added to steam explosion in order to produce glucose (for bioethanol production), and this increases profitability and reduces environmental impact of the steam explosion only flowsheet; however, the glucose flowrate from the steam explosion with acid hydrolysis flowsheet is low. The steam explosion with enzymatic hydrolysis flowsheet would be recommended to produce a higher glucose flowrate; however, the environmental impact of this flowsheet may be large if the electricity consumption of enzyme production is large.
