Preparation and manufacturing of nanomembranes based on ramie fiber using
electrospinning technique
- Abstract: In this study, ramie fibers were used to fabricate nanomembranes, which are expected to be able to filter micron/nano-sized particles. The ramie fibers were processed into cellulose pulp and processed into cellulose acetate. Ramie cellulose acetate is the basic material for making nanomembranes through an electrospinning process. Nanomembrane characterization was carried out using FTIR, ther...

Exploring the biodiesel potentials of waste avocado fruit oil
- Abstract: The biodiesel potential of waste avocado fruit was investigated. This study is essential for utilizing the enormous waste generated from avocado cultivation in Nigeria. Biodiesel was produced using a two-step acid-base catalyzed transesterification process. The acid catalyzed esterification step was required to convert the free fatty acids present in the oil to methyl esters. Important biodi...

Computational fluid dynamics (CFD) simulation of a gas-solid fluidized
bed: Residence time validation study
- Abstract: In this work, the business Computational Fluid Dynamics (CFD) is used for the numerical simulations of an air-solid fluidized bed container in the solid phase involving a multi-fluid Eulerian multiphase model and the Kinetic Theory of Granular Flow (KTGF). The height of the fluidized bed setup is 1.5 m while its diameter is 0.2 m. With it, a series of experimentations were obtained using Hel...

Assessment of the quality of hand dug well used for drinking and
agricultural activities at Blama, Small-Bo Chiefdom, Eastern, Sierra Leone
- Abstract: This research investigates the microbial and physicochemical characteristics of five local hand dug wells used for drinking and agricultural activities in Blama, Small-Bo Chiefdom, in the Kenema District, Eastern Province of Sierra Leone. These five local hand-dug wells were randomly selected based on the availability of water in them throughout the year. The physical characteristics examine...

Structural properties of high density polyethylene matrix composites
reinforced with open air and furnace rice husks ash
- Abstract: In this work, rice husks ash (RHA) was introduced to pure and recycled high density polyethylene (HDPE) matrix, at varying ration (0-50%) to formulate rice husks ash High density polyethylene (RHA-HDPE) composite. RHA was obtained by burning fresh rice husks either by open-air burning (oRHA) or furnace calcination at 700C (fRHA). The composite samples were made by melt-mixing the HDPE in an ...

Physicochemical characterization of Grewia species biopolymer, a potential
coagulation-flocculation agent
- Abstract: Powdered Grewia species barks was extracted in water and one part of the extract was precipitated with absolute ethanol. Both the crude water extract and the ethanol precipitate were freeze dried, pulverized into powder and subjected to physicochemical analyses. Amongst others, proximate composition, morphology and metal contents by Scanning Electron Microscopy with Energy Dispersive X-Ray (...

Analysis of the effect of feed composition and thermal conditions on
distillation plant performance using a computer model
- Abstract: This paper presents the effect of feed composition, xF, and feed thermal conditions on benzene-toluene distillation plant performance. An interactive computer model was developed to simulate the process using vapor-liquid equilibrium (VLE) data, mass and energy balances and McCabe-Thiele method. The feed thermal conditions studied were vaporized feed (VF), feed at its boiling point (FBP) and...

Extraction and characterization of chitin and chitosan from Callinectes
amnicola and Penaeus notialis shell wastes
- Abstract: In the current investigation, chitin and chitosan are extracted from Callinectes amnicola (crab) and Penaeus notialis (shrimp) shell wastes using predetermined optimization conditions. The shrimp shell produces higher chitin yield (26.08%), higher chitosan yield (16.93%) and higher degree of deacetylation (DDA) of 89.73% than the yields of chitin (19.36%), chitosan (13.29%) and the DDA from ...

Purification of cobalt solutions in several solvent extraction steps:
Using MEXTRAL and D2EHPA as extractants
- Abstract: A sulphate solution ofcobalt (18.93 g/L Co2+)containing major impurities such ascopper (1.35 g/L Cu2+), iron (0.28 g/L Fetot),zinc (0.70 g/L Zn2+) andmanganese (4.83 g/L Mn2+) was purified through thesolvent extraction methodusing two extractants; MEXTRAL and D2EHPA for the removal of copperand for the removal in two stages of a zinc-iron-manganese complex respectively. The effects of the so...
