Lignocellulosic carbon flow analysis of the South African paper industry.
(2018)This research study is one of five studies undertaken by the Paper Manufacturers Association of South Africa (PAMSA) to optimize the use of fibrous raw materials across the life-cycle phases of harvested wood products. ... -
Low-pressure vapour-liquid equilibrium and molecular simulation of carboxylic acids.
(2004)No abstract available. -
Mathematical modelling and experimental study of the kinetics of the acid sulphite pulping of eucalyptus wood.
(1992)The chemistry of the batch cooking process at Sappi Saiccor, relating to both the pulp and liquor, was investigated with the aim of using kinetic expressions to develop an improved process control model. The mill produces ... -
Mathematical modelling of climbing film evaporators.
(2001)Climbing film evaporators are in widespread use in the South African sugar industry, with the vast majority of the local sugar mills currently utilising these evaporators as first effect vessels in multiple effect ... -
Mathematical modelling of the dynamical interactions between killer and sensitive wine yeast subjected to nutritional stress.
(2000)No abstract available. -
Measurement of phase equilibria for oxygenated hydrocarbon systems
(2010)A number of industrially relevant separation processes involve carboxylic acids. Carboxylic acids are also amongst the various oxygenated products found in aqueous waste streams or as by-products of industrial operations ... -
Measurement of pure liquid molar heat capacities using a dual purpose differential flow calorimeter.
(2016)Abstract available in PDF file. -
Measurements of phase equilibrium for systems containing oxygenated compounds.
(2012)Accurate and reliable vapour-liquid equilibrium (VLE) and liquid-liquid equilibrium (LLE) data are the key to a successful design and simulation of most important industrial separation processes (traditional distillation, ... -
Metathesis of 1-hexene over a WO3/SiO2 catalyst in a gas-phase fixed bed reactor.
(2008)The performance of a WO3/SiO2 catalyst has been investigated for the metathesis of 1-hexene in an isothermal, gas-phase fixed bed tubular reactor between 420-500°C and at latm. The reactor was fabricated from stainless ... -
Metathesis of 1-hexene over heterogeneous tungsten-based catalysts.
(2013)Olefin (alkene) metathesis can be used for the redistribution of carbon bonds to produce preferred higher range carbon number olefins (C10-C16) from low value medium chain olefins such as 1-hexene. In this study, the ... -
Model predictive control of hybrid systems.
(2002)Hybrid systems combine the continuous behavior evolution specified by differential equations with discontinuous changes specified by discrete event logic. Usually these systems in the processing industry can be identified ... -
The modelling and control of a 1-octene dividing wall distillation column.
(2010-09-14)Partitioned or Dividing Wall Columns (DWC) for distillation are currently receiving a lot more -
Modelling and control of a co-current sugar dryer.
(2001)The drying of sugar is the last step in the recovery of solid sugar from sugar-cane. To ensure that the sugar can be transported and stored, the final moisture content leaving the sugar mill must be carefully controlled. Data ... -
Modelling and control of potable water chlorination.
(2003)In potable water preparation, chlorination is the last step before the potable water enters the distribution network. Umgeni Water Wiggins Waterworks feeds the Southern areas of Durban. A reservoir at this facility ... -
Modelling biological sulphate reduction in anaerobic digestion using WEST.
(2010-09-03)Researchers at Rhodes University conducted investigations into the anaerobic co-disposal of primary sewage sludge (PSS) and high sulphate acid mine drainage (AMD) resulting in the development of the Rhodes BioSURE Process® ... -
Modelling of a calcium looping fluidized bed reactor system for carbon dioxide removal from flue gas.
(2018)Abstract available in PDF file. -
Modelling of ionic interactions with organic components in wastewater.
(2014)In current biological wastewater treatment models, physico-chemical processes (ionic speciation reactions, gas-liquid exchange, and liquid-solid interactions such as precipitation and adsorption) either are not explicitly ... -
Modelling of the Marianridge wastewater treatment plant.
(2008)One of the consequences of the social and economIc change due to industrialisation is the generation of industrial wastewater which requires treatment before being released into the natural aquatic environment. The ... -
Modelling of the tubular filter press process.
(2000)The objective of this project was to develop a suitable procedure for the design, control and optimisation of the Tubular Filter Press. To this end, the following objectives were defined for this study: • To extend or ...
