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 ...
Grain regression analysis
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Grain regression analysis forms an essential part of solid rocket motor simulation.
In this thesis a numerical grain regression analysis module is developed
as an alternative to cumbersome and time ...
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 ...
Pyrolysis of sugarcane bagasse
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The world’s depleting fossil fuels and increasing greenhouse gas emissions have given rise to much
research into renewable and cleaner energy. Biomass is unique in providing the only renewable source ...
A novel approach to solvent screening for post-combustion carbon dioxide capture with chemical absorption
(Stellenbosch : Stellenbosch University, 2012-03-14)
ENGLISH ABSTRACT: Carbon dioxide (CO2) is classified as the main greenhouse gas (GHG) contributing to global warming.
Estimates by the Intergovernmental Panel on Climate Change (IPCC) suggest that CO2 emissions must ...
Establishment of a supercritical pilot plant and the hydrodynamics of supercritical countercurrent columns
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: Supercritical fluids are enjoying ever increasing popularity as a solvent medium for extraction,
stripping and absorption processes. Being readily tuneable and able to achieve sharp, highly
efficient ...
Modeling & optimisation of coarse multi-vesiculated particles
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: Multi-vesiculated particles (MVP) are synthetic insoluble polymeric particles containing a multitude
of vesicles (micro-voids). The particles are generally produced and used as a suspension in an
aqueous ...
