Teeter bed separation applications.
(2008)Elutriators or commonly known as Teetered Bed Separators (TBS) consist of a column with water being introduced at the base (known as teeter water), which rises up the elutriator at a constant velocity. Mineral particles ... -
Thermal drying of faecal sludge from vip latrines and characterisation of dried faecal material.
(2016)Ensuring safe, adequate, effective and sustainable sanitation is a major global challenge, especially in developing countries. This project is part of the ‘Reinvent the Toilet Challenge’ (RTTC) which focuses on the development ... -
Thermodynamic environmental fate modelling.
(2002)The labelling of methyl tertiary butyl ether (MTBE), an oxygenate additive used extensively in gasoline blending, as an environmentally harmful chemical has led to the banning and subsequent phasing-out of this additive ... -
Thermodynamic studies in CO2 capture through gas hydrate formation technology.
Abstract available in PDF file. -
The thermodynamics of liquids in solution at 298 K and 1 atm.
(2003)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 ... -
Time-series analysis of pressure fluctuation in gas-solid fluidized beds.
(2015)Fluidized beds have been used extensively in chemical process industries for several years. The success of fluidized operations is largely dependent on a well-defined and stable contact regime. Hence, the ability to ... -
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 ... -
Ultrafiltration of Lignin rock from black liquor obtained from a South African kraft mill.
(2015)This study focused on investigating the possibility of extracting lignin from black liquor generated from South African Kraft mill black liquors. Although ultrafiltration has been applied successfully and widely to extract ... -
A universal segment approach for the prediction of the activity coefficient.
(2016)This study comprised an investigation into solid-liquid equilibrium prediction, measurement and modelling for active pharmaceutical ingredients, and solvents, employed in the pharmaceutical industry. Available experimental ... -
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 ... -
The use of n-dodecane as a solvent in the extraction of light alcohols from water.
(2008)Phase equilibrium data is essential in the operation, design and development of industrial -
The use of water pinch analysis to determine optimum effluent treatment conditions for an integrated pulp and paper mill.
(2005)Pulp and paper mills are facing the possibility of stricter effluent discharge limits. End-of-pipe treatment for discharge no longer guarantees compliance, nor is it the most cost-effective way of solving mills' effluent ... -
Utilisation of bagasse for the production of C5- and C6- sugars.
(1982)Surplus sugarcane bagasse, estimated at a maximum of 0,9x106 tons/year, represents an annual renewable resource which is readily available at the mill site and is a suitable potential source of alternative fuels and ... -
Valorisation of waste chicken feathers: production of high-value materials.
(2018)Abstract available in PDF file. -
Vapour-liquid equilibria and infinite dilution activity coefficient measurements of systems involving diketones.
(2003)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 ... -
Vapour-liquid equilibria studies for binary systems containing 1-hexene and n-hexane
(2009)Experimental vapour-liquid equilibria (VLE) data is required for the design of separation -
Vapour-liquid equilibrium measurements at moderate pressures using a semi-automatic glass recirculating still.
(2014)Vapour-liquid equilibrium (VLE) data of high accuracy and reliability is essential in the development and optimization of separation and chemical processes. This study focuses on satisfying the growing demand for precise ... -
Vapour-liquid equilibrium measurements using a static total pressure apparatus.
(2006)A novel static total pressure apparatus was designed, built and commissioned for the measurement of VLE data at low to moderate pressures and temperatures. The apparatus of Fischer and Gmehling [1994] was used as a basis ... -
Vapour-liquid equilibrium of carboxylic acids.
(2005)VLE data is essential for the design and optimisation of industrial separation processes. Carboxylic acids are of significant interest because of their importance in both industrial and biological processes. Carboxylic ... -
Vapour-liquid equilibrium studies at low pressure using a static-cell cluster.
(2006)Phase equilibrium data are vital in process design for chemical industries. Development of
