Process modelling of sugar mill biomass to energy conversion processes and energy integration of pyrolysis
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: The sugar industry over the years has been producing sugarcane bagasse as part of the sugar milling process. Currently this sugar mill biomass is incinerated inefficiently as a means of their disposal to ...
The influence of gas and liquid physical properties on entrainment inside a sieve tray column
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: Distillation column design and operation require understanding of both the hydrodynamic
and thermodynamic behaviour and limitations. One of the hydrodynamic aspects that
negatively influence separation ...
Development of crosslinkable, thermoplastic polyurethanes for cardiovascular prostheses
(Stellenbosch : University of Stellenbosch, 2006-12)
Existing thermoplastic polyurethanes (TPUs), used in the manufacturing of
cardiovascular devices, still have unproven long-term biostability and may be prone to
excessive plastic deformation when subjected to cyclic ...
Separation of 1-dodecanol and n-tetradecane through supercritical extraction.
(Stellenbosch : Stellenbosch University, 2008-12)
Developments in the field of liquid detergents and cosmetics have increased the demand for
surfactants, processing aids and emollients. Alcohols are often used in liquid products where
they serve as solvents for the ...
Reactive absorption kinetics of CO2 in alcoholic solutions of MEA: fundamental knowledge for determining effective interfacial mass transfer area
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: The reactive absorption rate of CO2 into non-aqueous solvents containing the primary amine,
mono-ethanolamine (MEA) is recognised as a suitable method for measuring the effective
interfacial mass transfer ...
Examination of the thermal properties of municipal solid waste and the scalability of its pyrolysis
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Concerns surrounding the world’s current dependence on quickly depleting fossil fuels and their negative environmental impacts have brought about much research into renewable and sustainable energy sources. ...
The separation of detergent range alkanes and alcohol isomers with supercritical carbon dioxide
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Data on the process performance at different operating conditions are required to determine the
feasibility of a separation process. Such data can be experimentally measured, but due to the time and
costs ...
The processing of wax and wax additives with supercritical fluids
(Stellenbosch : University of Stellenbosch, 2005-12)
Waxes have many potential uses but large-scale application is hampered by their virtual
insolubility. By grafting the wax with a polyethylene glycol segment to form an alcohol ethoxylate,
the solubility of the wax in ...
Techno-economic study for sugarcane bagasse to liquid biofuels in South Africa : a comparison between biological and thermochemical process routes
ENGLISH ABSTRACT: A techno-economic feasibility study was performed to compare biological and
thermochemical process routes for production of liquid biofuels from sugarcane bagasse
in South Africa using process modelling. ...
Production of hollow fibers by co-electrospinning of cellulose acetate
(Stellenbosch : University of Stellenbosch, 2009-03)
The study concerns the use of the electrospinning technique for the formation of
cellulose acetate hollow nanofibers. These hollow fibers are used to manufacture
hollow fiber membranes. Important properties that should ...
