Fluidization and sedimentation behaviors of nanoparticles.
(2020)A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 to 100 nanometers in diameter. Nanoparticles were used by artisans since prehistoric times, albeit without knowledge of their ... -
Exploring the effectiveness of separation of pith/fibre fractions in sugarcane bagasse briquetting.
(2019)Abstract available in the PDF. -
The study of thermophysical and excess thermodynamic properties for the binary mixtures of imidazolium-based ionic liquids with polyethylene glycol 200.
(2020)Abstract available in the PDF. -
A study into the production of biodiesel using homogenously catalyzed transesterification reactions.
(2020)Abstract available in the PDF -
Synthesis and characterization of trioctylammonium dicarboxylate ionic liquids for heavy metal extraction from aqueous solutions.
(2020)Five hydrophobic trioctylammonium-based ionic liquids (ILs) functionalized with phthalate, succinate, adipate, suberate, and sebacate anions were synthesized for heavy metal extraction from aqueous solutions. The ILs were ... -
Production and optimisation of biodiesel using heterogeneous catalyst.
(2020)In this work, it is required to investigate the production and optimisation of biodiesel using heterogeneous catalyst to determine whether the resulting biodiesel may be utilised in an existing diesel engine without ... -
Wet and dry desulphurization technologies: modelling and simulation.
(2019)Energy demand continues to increase with population growth and economic development therefore numerous technologies have been proposed over the years to convert coal to electricity. Turbine cycles have received a great ... -
An investigation into the viscosity of C-massecuite using a pipeline viscometer.
(2017)Sugar is recovered by three stages of evaporative crystallisation, with each stage producing a two-phase mixture of sugar crystal and mother liquor commonly referred to as massecuite. The composition of each massecuite ... -
Development and verification of an Aspen Plus® model of a sugarcane biorefinery.
(2018)This dissertation describes a steady-state mass and energy balance model of a raw sugar mill which has been developed using the Aspen Plus® software. The Aspen Plus® model was designed to replicate an existing MATLAB model ... -
Carbon flow analysis of the South African paper converting, paper recycling and end user stage of paper.
(2017)Abstract available in pdf. -
Synthesis of hexafluorobenzene through batch reactive distillation.
(2018)South Africa is home to the second largest fluorspar (CaF2) reserves in the world, outside China; and it is consequently integral to the international supply of CaF2 to hydrogen fluoride producers. This is demonstrated ... -
Fractionation and valorisation of bark extractives from Eucalyptus species.
(2018)The notion of zero-waste in industrial production processes of widely used materials has gained momentum, as industries aim to gain revenue from waste materials which were previously considered as waste. Tree bark from ... -
Lignocellulosic carbon flow analysis of the South African paper industry.
(2018)This research study is one of five studies undertaken by the Paper Manufacturers Association of South Africa (PAMSA) to optimize the use of fibrous raw materials across the life-cycle phases of harvested wood products. ... -
Wetting and separation efficiency of polypropylene packing modified by nanoparticles.
(2018)Packed columns are one of the main unit operations used in distillation, extraction, absorption and hydrotreating due to their ease of operation, versatility and adaptability to different chemical systems. The distribution ... -
Development of Coordinated Methodologies for Modeling CO2-Containing Systems in Petroleum Industry.
(2018)Clathrate hydrates formation in natural gas processing facilities or transportation pipelines may lead to process and/or safety hazards. On the other hand, a number of applications are suggested on the basis of promoting ... -
Extension of a multi-criterion performance indicator model for post combustion Co2 capture using amine solvents.
(2018)Energy generation by carbonaceous fuel combustion has been identified as one of the predominant sources of CO2 emissions. Many scientists and researchers believe that rising CO2 levels have an adverse effect on the ... -
Delays and disruptions on construction projects within the public sector integrated project delivery system as an alternative.
(2017)The South African construction industry has earned a reputation for poor project delivery, particularly within the public sector. Successful project delivery has been identified as attaining the project objectives with ... -
Separation and recovery of a complexing agent in the production of lithium hexfluorophosphate.
(2019)A novel process for the production of lithium hexafluorophosphate (LiPF6) has been developed by NECSA (Nuclear Energy Corporation of South Africa). The starting materials include hexafluorophosphoric acid (HPF6) aqueous ... -
Nucleation induced by high frequency sound for the production of sugar refinery seed crystals.
(2016)The crystallisation process is the second oldest unit operation in existence and a sine qua non in the production of crystalline sugar. It comprises two distinct phases viz. nucleation and the growth of the subsequent ... -
Hydrocracking of short residue over unsupported and supported magnetite nanocatalysts.
(2017)With the rapid depletion of crude oil and current cracking methods of heavy petroleum residue all resulting in the production of undesirable coke formation, a better solution must be found. This project investigated the ...
