The development of a method for the inclusion of salinity effects into environmental life cycle assessments.
The work presented in this thesis stemmed out of the apparent lack of a method for incorporating salinity effects into environmental life cycle assessments. Salination of the water resources is a well-known problem in South ...
Ionic liquids as solvents in separation processes.
Due to the ever increasing need for sustainable development, the chemical and allied industries have been at the focus of much change. Decreasing tolerances on pollution via waste streams has resulted in a re-examination ...
An investigation into a lower temperature and low cost direct reduction process for iron-making.
The blast furnace process for the reduction of iron ore to pig iron faces problems such as emission of air pollutants, high investment cost and the current major problem of decreasing supplies of coke. Coke is used ...
A pre-screening tool for the anaerobic treatment of complex industrial effluents and wastewaters.
The objective of this investigation was to assess the potential of a titration bioassay i.e.: The Methanogenic Activity and Inhibition Analyser (MAlA), to determine the biodegradability of complex industrial effluents ...
Application of pinch technology in an integrated pulp and paper mill.
The objective of this investigation was to utilise water pinch analysis as a tool for the optimisation of fresh water use in an integrated pulp and paper mill. The investigation was carried out at Mondi Paper in Merebank, ...
Modelling and control of potable water chlorination.
In potable water preparation, chlorination is the last step before the potable water enters the distribution network. Umgeni Water Wiggins Waterworks feeds the Southern areas of Durban. A reservoir at this facility ...
The thermodynamics of liquids in solution at 298 K and 1 atm.
For many years the problem of separating aliphatic and aromatic compounds has been at the forefront of the petroleum and oil refining industries. This separation is often effected using liquid-liquid extraction or ...
Vapour-liquid equilibria and infinite dilution activity coefficient measurements of systems involving diketones.
Acetylpropionyl (2,3-pentanedione) and diacetyl (2,3-butanedione) are by-products of sugar manufacture. Both diketones have many uses, mainly food related. Vapour-liquid equilibrium data and infinite dilution activity ...
Production of activated carbon from South African sugar-cane bagasse.
The South African sugar industry generates excessive amounts of sugar cane bagasse (~ 25 wt% of feed) as a byproduct during the extraction of sugar juice from cane. Although bagasse is extensively consumed in various ...
