A Study of boiling parameters under conditions of laminar non-Newtonian flow with particular reference to massecuite boiling.
(1985)Crystallization is done in the sugar industry using natural circulation vacuum evaporative crystallizers known as vacuum pans. the fluid which is known as massecuite consists of a suspension of crystals in concentrate ... -
A high resolution model for multiple source dispersion of air pollutants under complex atmospheric structure.
(1986)No abstract available. -
The solid state reduction of chromite.
(1989)High carbon ferrochromium serves as the main chromium source for almost all chromium containing steel alloys. The traditional method for the production of high carbon ferrochromium via the reduction of chromite using ... -
Measurement and thermodynamic interpretation of high pressure vapour-liquid equilibrium data.
(1990).. Detailed experimental and thermodynamic studies of. the isothermal phase equilibria for the -
The kinetics of steam gasification of South African coals.
(1990)The prime objective of a current research project at the University of Natal is to develop a novel autothermal fluidised bed coal gasifier which is capable of efficiently producing synthesis quality gas (rich in hydrogen ... -
Modelling of turbulent cross-flow microfiltration of particulate suspensions.
(1991)No abstract available. -
Performance studies of the tubular filter press.
(1992)The tubular filter press is a novel tubular configured filter press for the filtration or dewatering of sludges. The unique features of the filter press are: (i) during the cake deposition cycle, cake is deposited on ... -
A study of comminution in a vertical stirred ball mill.
(1993)A 20 litre experimental batch and continuous test rig and 5 litre batch and 50 litre continuous test rigs for stirred ball milling were built at the University of Natal and Mintek respectively. All the mills featured a ... -
The recovery of sodium hydroxide from cotton scouring effluents.
(1994)This dissertation describes the characterisation of, and development of a novel integrated waste management strategy for, hydroxide scouring effluents produced during cotton processing. Such effluents are typical of ... -
A study of the phenomenon of bridging of sugarcane bagasse
(1996)This work reports the results of a systematic study of the factors that affect the bridging behaviour of bagasse. It shows that traditional bulk solids theory is inappropriate for predicting bagasse flow mainly because ... -
Municipal wastewater characterization : application of denitrification batch tests.
(1999)The biological treatment of wastewater has evolved significantly from simple single sludge systems practicing organic carbon removal to ones which now include either nitrification/denitrification (N/DN) and / or phosphorus ... -
High pressure phase equilibrium studies.
(2018-09-17)This project involved the design, construction and commissioning of a new isothermal multipmpose high-pressure vapour-liquid equilibrium (HPVLE) apparatus of the static type. The equilibrium cell was approximately 200 ... -
An investigation of advanced oxidation processes in water treatment.
(2001)The deteriorating water quality in South Africa and changing legislation requiring the industrial implementation of waste minimisation and pollution prevention technologies has highlighted the need for the investigation ... -
Dynamic modelling and optimal control of sugar crystallisation in a multi-compartment continuous vacuum pan.
(2002)The objective of this work was to determine the operating conditions which would maximise the crystallisation performance of continuous vacuum pans used in the sugar industry. The specific application investigated in detail ... -
Treatment of dye wastewaters in the anaerobic baffled reactor and characterisation of the associated microbial populations.
(2002)There is potential for the anaerobic baffled reactor (ABR) to be implemented on-site for pre-treatment of coloured wastewaters. The implementation of waste minimisation and cleaner production strategies in industry ... -
Spatio-temporal dynamics of heterogeneously distributed populations.
(2003)No abstract available. -
The development of a method for the inclusion of salinity effects into environmental life cycle assessments.
(2003)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 ... -
Robust equipment for the measurement of vapour-liquid equilibrium at high temperatures and high pressures.
(2004)In this work VLE data was measured on three different pieces of equipment. Measurements were undertaken in the laboratory of Professor Gmehling in Oldenburg, Germany using two different static cells and in the Thermodynamics ...
