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 ...

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. ...

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. ...

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 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 ...

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 ...

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 ...

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 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 effectiveness of selected extractive agents for the separation of n-propanol and 2-butanol was evaluated with the aid of a circulation vapour-liquid equilibrium still. The difference in boiling points between n-propanol ...
