Measurement and thermodynamic interpretation of high pressure vapour-liquid equilibrium data.
(1990).. Detailed experimental and thermodynamic studies of. the isothermal phase equilibria for the -
Membrane distillation of concentrated brines.
(2010-10-29)Salinity is one of the most critical environmental problems for water scarce countries, -
Modelling of a vibrating-plate extraction column.
(2010)Liquid extraction, sometimes called solvent extraction, is the separation of the constituents of a liquid solution by contact with another insoluble liquid. It belongs to the class of countercurrent diffusional separation ... -
Modelling of turbulent cross-flow microfiltration of particulate suspensions.
(1991)No abstract available. -
Molecular targeting of refrigerant mixtures.
(2014)Refrigeration units, besides common household refrigerators and air conditioning systems, are necessary components for the successful operation of many industrial processes in the chemical, petrochemical, pharmaceutical ... -
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 ... -
Neural network modelling and prediction of the flotation deinking behaviour of complex recycled paper mixes.
(2011)In the absence of any significant legislation, paper recycling in South Africa has grown to a respectable recovery rate of 43% in 2008, driven mainly by the major paper manufacturers. Recently introduced legislation will ... -
Neural network models for leukaemia.
(2009)Artificial neural networks (ANN) can detect complex non-linear relationships between independent and dependent variables. Properly trained ANNs have repeatedly demonstrated superior predictive accuracy to other predictive ... -
Optimal design of a secondary milling circuit for treating chromite-rich UG-2 platinum ores.
(2011)Extraction of platinum group elements (PGE) is a major source of revenue in South Africa and the reserves represent about 75 per cent of world reserves. Most of the remaining Platinum Group Mineral (PGM) reserves are located ... -
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 ... -
Precipitation and valorisation of lignin obtained from South African kraft mill black liquor.
(2016)Abstract available in PDF file. -
The prediction of multicomponent ion exchange equilibria with particular reference to the system involved in the recovery of uranium.
(1976)The problem of predicting the general ion exchange equilibria pertaining to systems of industrial significance is generated by the multicomponent nature of such systems and the nonidealities which may be present in both ... -
Prediction of the physical properties of pure chemical compounds through different computational methods.
(2014)Liquid thermal conductivities, viscosities, thermal decomposition temperatures, electrical conductivities, normal boiling point temperatures, sublimation and vaporization enthalpies, saturated liquid speeds of sound, ... -

Pyrolysis-gas chromatography/mass spectrometry study of chromophores in dissolving wood pulp.
(2018)Dissolving wood pulp (DWP) is bleached wood pulp that contains high cellulose content, typically >95%. The bleaching is done to remove remnants of lignin and hemicelluloses that are not necessary for the final DWP. The ... -
