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 ... -
High pressure vapour-liquid equilibrium data of fluorochemical systems for various temperatures using a new static apparatus.
(2010)The thermodynamic knowledge of accurate phase equilibrium data plays an important role in the design and optimization of separation processes in chemical and engineering industries. Vapour-liquid equilibrium data are ... -
High pressure vapour-liquid equilibrium measurement for perfluorinated chemicals using a static analytical apparatus.
(2016)Abstract available in PDF file. -
High pressure vapour-liquid equilibrium measurements for R116 and ethane with perfluorohexane and perfluorooctane.
(2016)Isothermal binary vapour-liquid equilibrium data are presented for gas –liquid systems for R116 and ethane with perfluorohexane and perfluorooctane. There are no data in the open literature for these systems except for ... -
A high resolution model for multiple source dispersion of air pollutants under complex atmospheric structure.
(1986)No abstract available. -
High temperature flue gas desulfurization: experiments and modelling.
(2018)As stringent environmental regulations regarding SO2 emissions have been enacted in many countries, the removal of SO2 from flue gas has become a necessity. Conventional methods for flue gas desulfurization (SO2 removal) ... -
Highly dispersed zinc-based sorbents for desulphurisation : synthesis and application.
(2016)Abstract available in PDF file. -
Hydrate phase equilibrium data of CO2+H2O+Tetrabutyl ammonium salts (chloride and fluoride).
(2014)The UNFCC’s (United Nations Framework Convention on Climate Change) goal, to stabilize greenhouse gas concentrations through energy technology and prevent anthropogenic interference with the climate system, has led to ... -
Hydrate phase equilibrium studies for Xe, Ar, Kr, and CF4 in the presence of TBAB aqueous solutions.
(2015)Abstract available in PDF file. -
Hydrate technology for the concentration of aqueous salt solutions using fluorinated refrigerants.
(2019)The world is facing a challenge with the scarcity of fresh water, due to an increase in the world population and the large expansion of industrial projects. This results in greater demand for fresh water. In such a scenario, ... -
Hydrocracking of short residue over unsupported and supported magnetite nanocatalysts.
(2017)With the rapid depletion of crude oil and current cracking methods of heavy petroleum residue all resulting in the production of undesirable coke formation, a better solution must be found. This project investigated the ... -
Hydronamic study of gas-liquid co-current bubble column reactors at low superficial gas velocities.
(2005)Sasol's Research and Development Division has identified several proprietary gas-liquid reactions where very low superficial gas velocities « 0.8 cmls) are required to obtain desired conversions in a bubble column reactor. ... -
Impact of hexenuronic acid on the physical and chemical properties of eucalyptus clonal pulps during ECF bleaching .
(2007)The work described in this dissertation was aimed at obtaining an understanding of -
The impact of low consistency refining of eucalyptus species on the fibre morphology and strength properties of pulp.
(2005)It is a well-known fact that the selection of the raw material and how it is further treated within the stock preparation system has a major affect on the quality of paper obtained. While the pulp selection is important ... -
The impact of the chemical and physical properties of Pinus patula on pulp and pulp strength properties.
(2005)Due to the opportunity for afforestation in South Africa being severely limited, extensive research is being carried out on obtaining more wood per given area, improving the quality and value of the wood and on gaining a ... -
Industrial chromatographic separation of mono-valent amino acids.
(2005)The aim of the thesis was to optimise the separation and purify an amino acid solution consisting of mono-valent amino acids. Amino acids have historically been separated by chromatographic separation for analytical ... -
Industrial waste minimisation in South Africa : a case study in the textile and metal finishing sectors.
(2002)Environmental legislation is becoming more stringent as people are realising the need for conservation and a reduction of environmental degradation in order to facilitate sustainable development. To ease legislative ... -
Infinite dilution activity coefficient measurements of organic solutes in fluorinated ionic liquids by gas-liquid chromatography and the inert gas stripping method
(2009)Environmental and safety concerns have prompted an active quest for ―green‖ alternatives to -
An integrated computational fluid dynamics an kinetics study of ozonation in water treatment.
(2005)Computational fluid dynamic (CFO) modelling has been applied to examine the operation of the prc-ozonation system at Wiggins Waterworks, operated by Umgeni Water in Durban, South Africa. Ozonation is employed in water ...
