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 ... -
An investigation into a lower temperature and low cost direct reduction process for iron-making.
(2003)The blast furnace process for the reduction of iron ore to pig iron faces problems such as emission of air pollutants, high investment cost and the current major problem of decreasing supplies of coke. Coke is used ... -
An investigation into factors increasing contamination risk posed by fuel storage facilities and concomitant methods to mitigate these risks.
(2011)Light Non-Aqueous Phase Liquids (LNAPLs) are used throughout the world for numerous applications, the most well-known being automotive fuels, such as petrol and diesel. The widespread production, distribution, storage ... -
An investigation into the application of multiple criteria decision analysis as a decision support tool for municipal engineers.
(2015)A Multiple Criteria Decision Analysis (MCDA) was developed for the selection of sanitation systems. This decision support system was aimed at assisting municipal engineers to design and implement sustainable solutions ... -
An investigation into the characteristics of on-site faecal sludge in Durban in a study of Ventilated Improved Pit (VIP) latrines and Urine Diversion (UD) toilets.
(2016)Abstract available in PDF file. -
Investigation into the effect of stripped gas liquor on the anaerobic digestion of Fischer-Tropsch reaction water.
(2014)The Fischer-Tropsch reaction technology is utilised in Sasol’s Coal-to-liquid plant to produce liquid fuels from low grade coal. There are several processes on the Coal-to-liquid plant that generate aqueous streams which ... -
Investigation into the effects of froth height in a flotation cell.
(1971)Abstract available in PDF file. -
An investigation into the potential of NFM, DEG and TEG as replacement solvents for NMP in separation processes.
(2012)Optimisation attempts within the petrochemical industry have led to interest in alternate solvents. The most widely used commercial solvents for the separation of hydrocarbons, by extractive distillation, are N-methylpyrrolidone ... -
An investigation into the use of fluorinated hydrating agents in the desalination of industrial wastewater.
(2011)Salts in solution should be removed by desalination techniques to prevent equipment fouling and corrosion. Common desalination technologies are energy intensive such as Multi Stage Flash (MSF) distillation which requires ... -
An investigation into the viscosity of C-massecuite using a pipeline viscometer.
(2017)Sugar is recovered by three stages of evaporative crystallisation, with each stage producing a two-phase mixture of sugar crystal and mother liquor commonly referred to as massecuite. The composition of each massecuite ... -
An investigation into the viscosity of heavy medium suspensions.
(2005)This project investigated the viscosity of heavy medium suspensions. Heavy medium suspensions are used extensively in the minerals processing industry for separation of valuable materials from gangue on the basis of ... -
An investigation of a two-step, temperature-staged, direct coal liquefaction process.
(2015)From its inception in the 1700’s, deriving fuel from the Direct Coal Liquefaction (DCL) process has spawned numerous pursuits. While coal is an abundant fossil fuel in many countries and represents approximately 70% of the ... -
An investigation of a waste minimisation club for the metal finishing industry.
(2002)Take care how you place your moccasins upon the earth, step with care, for the faces of the future generations are looking upfrom the earth waitingfor their turnfor life - Lyoru, 1988 Increasing levels of pollution and ... -
