Applications of fluorocarbons for supercritical extraction in the petroleum industry.
(2016)The majority of supercritical processes utilise carbon dioxide (CO2) as the principal solvent, because CO2 has many attributes that make it an ideal supercritical fluid (SCF) solvent. This study investigates the possibility ... -
Application of gas hydrates in cold storage technology : experimental study and thermodynamic modeling.
(2015)The ever-increasing demands for air conditioning technology especially in residential areas results in a severe imbalance between power generating utilities, especially during peak usage hours. To provide the required peak ... -

Unlike interactions in simulated methane clathrate hydrates.
(2014)Clathrate hydrates are an ice-like substance consisting of networks of water molecules, held together by hydrogen bonds, enclosing trapped gas molecules. Natural gas clathrate hydrates (in which the trapped gas species ... -
Molecular targeting of refrigerant mixtures.
(2015-11-27)Refrigeration units, besides common household refrigerators and air conditioning systems, are necessary components for the successful operation of many industrial processes in the chemical, petrochemical, pharmaceutical ... -
Representation/prediction of physico-chemical properties of ionic liquids through different computational methods.
(2015-10-30)The “green” industrial chemical processes are of great interest to scientists and engineers due to elimination of environmental pollution, especially air pollution. One of the most important air pollutants is class of ... -
Prediction of the physical properties of pure chemical compounds through different computational methods.
(2014)Liquid thermal conductivities, viscosities, thermal decomposition temperatures, electrical conductivities, normal boiling point temperatures, sublimation and vaporization enthalpies, saturated liquid speeds of sound, ... -
Scientific and management support for ventilated improved pit latrines (VIP) sludge content.
(2014)Providing adequate sanitation to all in the form of VIP latrines as proposed by the South African Government Strategic Framework for Water Services does not end with building toilets. All municipalities need to plan for ... -

An investigation into the effects of UG2 Ore variability on froth flotation.
(2014-09-23)South Africa is the world’s largest producer of platinum group elements (PGEs). Mining takes place in the Bushveld Complex, and recent statistics, (Mudd, 2010), showed that the UG2 reef is the main source of production, ... -
Carbon dioxide removal from coal power plants : a review of current capture techniques and an investigation of carbon dioxide absorption using hybrid solvents.
(2014-07-03)The aim of this project was to identify and assess all possible solutions to reduce carbon dioxide (CO2) emissions from coal power plants in South Africa, identify the most likely solution to be implemented industrially ... -
An investigation of a supersonic chemical reactor.
(1977)The development of a supersonic chemical reactor is examined. The central concept of such a reactor is that gases can be expanded to supersonic speed which will result in a decrease in their static temperature to the ...
