Aerosol synthesis of ceramic particles by seed growth : analysis of process constraints
(Stellenbosch : Stellenbosch University, 2002-04)ENGLISH ABSTRACT: Aerosol synthesis involves the formation of condensable product species by gas-phase reaction, and the simultaneous growth of particles by coagulation. For the production of ceramic particles, reaction ... -
Alkaline polyol fractionation of sugarcane bagasse and eucalyptus grandis into feedstock for value added chemicals and materials
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH SUMMARY: The main components of lignocellulosic biomass cellulose, hemicellulose and lignin are feedstock for chemical and material manufacturing processes. Integrated biorefinery processes incorporate the production ... -
Ammonium thiosulphate leaching of gold from printed circuit board waste
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH SUMMARY: Technological innovation leads to a reduced lifespan of older electrical and electronic equipment, which in turn leads to the generation of vast quantities of electronic waste (e-waste). The recycling of ... -
Anaerobic co-digestion of fruit juice industry wastes with lignocellulosic biomass
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The fruit juice industry in South Africa forms an important part of the South African economy, however it generates large quantities of liquid and solid organic wastes. Landfilling is typically used to ... -
Analysis and modelling of mining induced seismicity
(Stellenbosch : University of Stellenbosch, 2006-12)Earthquakes and other seismic events are known to have catastrophic effects on people and property. These large-scale events are almost always preceded by smallerscale seismic events called precursors, such as tremors ... -
Analysis of process data with singular spectrum methods
(Stellenbosch : University of Stellenbosch, 2003-12)ENGLISH ABSTRACT: The analysis of process data obtained from chemical and metallurgical engineering systems is a crucial aspect of the operating of any process, as information extracted from the data is used for control ... -
Antimicrobial lipopeptide production by Bacillus spp. for post-harvest biocontrol
(Stellenbosch : Stellenbosch University, 2014-12)ENGLISH ABSTRACT: As overpopulation threatens the world’s ability to feed itself, food has become an invaluable resource. Unfortunately, almost a third of the food produced for human consumption is lost annually. Pests ... -
Application of membrane technology for purifying tyre derived oil
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH SUMMARY: Tyre derived oil (TDO) is an abundant liquid product obtained after pyrolysis of waste tyre. It contains a complex mixture of C6–C24 organic compounds of various classes such as paraffins, olefins, aromatics, ... -
Applying dynamic Bayesian Networks to process monitoring
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: In efforts to reduce the impact of human error on the operation of chemical and mineral processing plants, reliable process monitoring solutions attempt to assist plant operators and engineers to detect ... -
