A macroscopic determination of the impact of Lethabo coal quality upon the optimum combustion air quantity
(Potchefstroom University for Christian Higher Education, 1999)
Lethabo Power Station burns a unique low grade coal with low volatile content. This merits the optimisation of the total combustion air quantity with efficiency as main criterion to produce an air flowsteam flow curve as ...
Fischer-Tropsch studies in the slurry phase favouring wax production
(North-West University, 1994)
The Fischer-Tropsch synthesis over iron and cobalt based catalysts has been investigated in the slurry phase. Reaction conditions were restricted to those conducive for the optimum production of synthetic wax (i.e. high ...
The skeletal isomerisation of the N–butenes catalyst performance and kinetic investigation
(Potchefstroom University for Christian Higher Education, 1998)
With the advent of catalytic converters being placed in the exhaust systems of motor
vehicles, in an attempt to reduce pollution, the use of tetra ethyl lead as an anti-knock
additive to fuel was no longer acceptable. ...
Hydrodynamic studies and reactor modelling of a three phase slurry reactor in Fischer Tropsch application
(Potchefstroom University for Christian Higher Education, 1992)
In this .study the hydrodynamic characteristics of the slurry bed reactor was investigated. This study was aimed to the under" standing of the important parameters that describe the hydrodynamic regime and their quantification. ...
Numerical simulation of the plastics moulding process using a thin gap numerical model
(Potchefstroom University for Christian Higher Education, 1995)
The injection moulding process is one of the most popular means of mass producing components to very small tolerances. Before the advent of the affordable computer, the methods used in injection mould design were empirical ...
Simulation of a micro heat pump cycle
(1998)
The purpose of this study was to develop a thermal cycle simulation for a micro heat pump. A feature of the simulation is that it can simulate the four qasic components in detail, based on fundamental principles. The product ...
The use of crosslinked polyethylene for the manufacturing of membranes
(Potchefstroom University for Christian Higher Education, 1999)
Increasing environmental awareness over the past decade as well as stringent
environmental laws forced all factories to invest in water treatment processes for
effluent treatment before discharge or re-use. Most of these ...
The development and implementation of new TTC flotation chemicals
(Potchefstroom University for Christian Higher Education, 1998)
Batch floats were done on Merensky ore from Section 10 at Impala Platinum. The ultimate objective of this project was a pilot plant trial and certain questions had to be answered before the trial could be conducted. To ...
The management and implementation of a data terminal project on a global system for mobile communications
(Potchefstroom University for Christian Higher Education, 1999)
With the demand for more control over remote systems and access to remote data increasing, there
existed the need for a more efficient and low cost means of transmitting this data. Traditionally, small
telemetry data ...
The effect of selected solvents on the relative volatility of the binary system: 1–octene – 2–hexanone with the aim of separating the azeotropic mixture
(Potchefstroom University for Christian Higher Education, 1994)
The removal of oxygenates from olefins has tremendous industrial
significance. This study dealt specifically with potential
azeotropic and extractive distillation processes for the
purification of higher alpha olefins.
An ...
