Development of a dynamic still for measuring low pressure vapour-liquid-liquid equilibria : systems of partial liquid miscibility.
(2005)The dynamic still originally designed by Raal (Raal and Muhlbauer [1998]) has been transformed into a valuable still that can now be used for measuring both low pressure vapour-liquid equilibria (VLE) for systems that are ... -
Development of a group contribution method for the prediction of normal boiling points of non-electrolyte organic compounds.
(2004)Physical properties are fundamental to all chemical, biochemical and environmental industries. One of these properties is the normal boiling point of a compound. However, experimental values in literature are quite limited ... -
The development of a hybrid activity coefficient model utilizing the solution of groups concept.
(2011)During the course of this thesis the UNIFAC method (group-based method) was regressed to individual Px(T) binary datasets, and the results are compared to the regression results using the Wilson, NRTL, and UNIQUAC equations ... -
Development of a model of the aerobic membrane bioreactor treating Illovo wastewater.
(2014)The Membrane Bioreactor (MBR) at Sezela, KwaZulu-Natal treats a process effluent emanating from a sugar industry by-products plant. Depending primarily on the effluent feed rate to the MBR as well as other less significant ... -
Development of a performance indicator model for carbon capture applications.
(2017)Abstract available in PDF file. -
Development of a pilot scale black liquor gasifier.
(2011-05-04)The use of black liquor gasification as an alternative to conventional chemical and energy recovery systems for spent liquors is an area of particular interest to the pulp and paper industry. The motivation to explore this ... -
Development of a thermodynamic model for the purification of 1-hexene.
(2007)The South African based petrochemical company, SASOL, operates three large plants for the recovery and purification of the chemical 1-hexene. The thermodynamic models available in commercial simulation packages fail to ... -
The development of a three-phase filtration cell
(2010)The chemical and process industries rely largely on filtration processes to separate solid-liquid process -
The development of a weighted directed graph model for dynamic systems and application of Dijkstra’s algorithm to solve optimal control problems.
(2017)Optimal control problems are frequently encountered in chemical engineering process control applications as a result of the drive for more regulatory compliant, efficient and economical operation of chemical processes. ... -
The development of an experimental technique for UG-2 ore flotation.
(2013)Production of platinum and associated metals is a major source of revenue for South Africa. Significant losses occur in the concentrating stage (10 to 15 per cent) and this research is focused on optimising platinum ... -
Development of an improved group contribution method for the prediction of vapour pressures of organic compounds.
(2007)Vapour pressure is an important property in the chemical and engineering industries. There are -
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 ... -
Dry beneficiation of coal using an air dense-medium fluidised bed separator
(2010)The mining of coal in arid regions has led to calls for research in to the field of dry beneficiation, -
Drying and pasteurisation of vip latrine faecal sludge using a bench scale medium infrared machine.
(2017)The main challenge with Ventilated Improved Pit (VIP) latrines is that they eventually fill up. Solutions therefore have to be sought with the common practice being to cover up the hole and dig a new pit. This however is ... -
Dynamic modelling of anaerobic digestion of Fischer-Tropsch reaction water.
(2013)Fischer-Tropsch Reaction Water (FTRW) is a high organic strength wastewater produced as a by-product in Sasol’s Fischer-Tropsch Reactors. Typically it has an organic load of 18000 mgCOD/L and is highly acidic with a pH ... -
Economic recovery of biobutanol-a platform chemical for the sugarcane biorefinery.
(2018)In recent years, the South African sugar industry has faced challenges, such as drought, low prices and labour issues that have impacted negatively on the perceived sustainability. The adoption of the sugarcane biorefinery ... -
The effect of particle properties on fluidized bed hydrodynamics and entrainment.
(2007)This study focuses on the effect that particle properties (size, density and shape) have on fluidized bed hydrodynamics and entrainment rate. The experimental work was carried out using two Plexiglas columns having ... -
Environnmental life cycle assessment of potable water production.
(2001)This study investigates and compares the environmental burdens of two different methods for producing potable water by using the environmental life cycle assessment (LCA). The first method, for the production of potable ... -
The evaluation of ozone technology to reduce the concentration of polychlorinated biphenyls (PCBs) in contaminated soil.
(2011)Polychlorinated Biphenyls (PCBs) are hazardous and toxic chemicals to both humans and animals. In the late 1960’s PCBs were discovered to be a harmful pollutant which could cause environmental contamination due to its ... -
Evaluation of paper substrates for microfluidic application in medical diagnostic kits.
