The evaluation of the fluidised bed combustion performance of South African coals in the presence of sorbents.
The Fluidised Bed Combustion (FBC) technology has been widely used internationally for power generation. This technology has good fuel flexibility and reduced S02 emissions with dry sorbent (Limestone or Dolomite) addition. ...
Application of a non-linear transformation to the surface fraction of the UNIQUAC model and the performance analysis of the subsequent model (FlexQUAC-Q).
GE-model and equations of state are used to describe and predict phase equilibria. Current models have varying capabilities and some display selectivity for certain special mixtures. While many models are superior to others ...
The effect of particle properties on fluidized bed hydrodynamics and entrainment.
This study focuses on the effect that particle properties (size, density and shape) have on fluidized bed hydrodynamics and entrainment rate. The experimental work was carried out using two Plexiglas columns having ...
Development of a thermodynamic model for the purification of 1-hexene.
The South African based petrochemical company, SASOL, operates three large plants for the recovery and purification of the chemical 1-hexene. The thermodynamic models available in commercial simulation packages fail to ...
A gate-to-gate life cycle assessment of a pulp and paper mill in South Africa.
Life Cycle Assessment (LCA) is a tool for the evaluation of environmental impacts of a
Impact of hexenuronic acid on the physical and chemical properties of eucalyptus clonal pulps during ECF bleaching .
The work described in this dissertation was aimed at obtaining an understanding of
Development of an improved group contribution method for the prediction of vapour pressures of organic compounds.
Vapour pressure is an important property in the chemical and engineering industries. There are
Investigation of the potential to develop high pulp strength from high yield Kraft pulp made from Pinus patula.
The major focus of this study was to provide better understanding of the potential of
Removal of reactive dyes from dye liquor using activated carbon for the reuse of water, salt and energy.
The removal of colour from effluent after dyeing of cellulosic fibres is a major problem due to the difficulty in treating such effluents by conventional treatment methods. Cellulosic fibres of a specific shade (colour) ...
