Flue gas desulphurization using natural calcium based sorbents.
(2013)Power generation from coal combustion serves as a major source of energy however this process has detrimental environmental effects. SO₂ is a destructive pollutant and is oxidized with water vapour to form sulphuric acid ... -
Fluidised bed gasification of spent soda and sulphite liquors from the paper industry.
(2004)The pulp and paper industry uses pulping chemicals for the treatment of bagasse, straw and wood chips. Spent liquor or effluent liquor, with high carbon content is produced and sent to chemical recovery to recover pulping ... -
Forward osmosis of stored urine.
(2016)Source separation of urine from domestic waste water provides a sustainable way of managing nutrient and water recovery from urine. This study was performed in the context of the Bill &Melinda Gates (BMFG) foundation’s ... -
Fractionation and valorisation of bark extractives from Eucalyptus species.
(2018)The notion of zero-waste in industrial production processes of widely used materials has gained momentum, as industries aim to gain revenue from waste materials which were previously considered as waste. Tree bark from ... -
Gas-phase ethylene polymerization studies using a magnesium chloride-supported Ziegler-Natta catalyst.
(2006)The gas phase polyethylene production process is the most recently developed and boasts many -
A gate-to-gate life cycle assessment of a pulp and paper mill in South Africa.
(2007)Life Cycle Assessment (LCA) is a tool for the evaluation of environmental impacts of a -
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 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 ... -
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 ... -
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 -
Inverse internal model control of an ethylene polymerisation reactor using artificial neural networks.
(2001)An artificial neural network is a mathematical black-box modelling tool. This tool can be used to model complex non-linear multivariable processes. In attempting to create an inverse process model of an industrial linear ...
