The influence of design parameters on the occurrence of shielding in multi-electrode ESPs and its effect on performance
(Elsevier, 2018)
A numerical model in which OpenFOAM® is used to model the electrostatic field resulting from corona discharge in single-channel wire-plate electrostatic precipitators (ESPs) was applied to systematically study the shielding ...
Thermal reduction of barium sulphate with carbon monoxide: a thermogravimetric study
(Elsevier, 2010)
The kinetic parameters of the reduction of barium sulphate to barium sulphide using carbon monoxide fractions of 2.4–9.6% and temperatures of 850–1000 °C, using an isothermal thermogravimetric method, were obtained. This ...
Update temperature control for a Claus unit with neural networks
(Gulf Publishing Company, 2013)
The Natref Oil Refinery in Sasolburg, South Africa, experienced refractory problems in the combustion chamber of the Sulphur Recovery Unit (SRU) since start-up (Figure 1). Even though the SRU was at all times operated ...
CFD modeling of particle charging and collection in electrostatic precipitators
(Elsevier, 2016)
A CFD model was developed to describe the particle laden gas flow through an ESP, particle charging and collection. The corona discharge was modeled using the open source software OpenFOAM to solve the Poison and charge ...
Sulphur trioxide decomposition with supported platinum/palladium on rutile catalysts. 1. Reaction kinetics of catalyst pellets
(Elsevier, 2015)
An investigation was undertaken to evaluate the intrinsic reactivity, stability and associated diffusional parameters of catalyst pellets consisting of platinum and palladium on rutile for the conversion of sulphur trioxide ...
Manufacturing of briquettes from typical highveld coal fines using various binders
(Swanson School of Engineering, Univ of Pittsburgh, 2015)
A comparative study of the processing scheme of chitosan and Nafion 117 in membrane electrode assembly
(Taylor & Francis, 2013)
The authors considered two fabrication techniques in the fabrication of the membrane electrode
assembly. It was observed that catalytic deposition through electro-spraying was not successful for
chitosan and Nafion 117 ...
The properties of large coal particles and reaction kinetics of corresponding chars
(Elsevier, 2015)
An investigation was undertaken to determine the distribution of chemical-, petrographic- and mineralogical properties of large coal particles of different sizes and densities and to evaluate a suitable reaction rate model ...
Influence of additives on the devolatilization product yield of typical South African coals, and effect on tar composition
(SAIMM, 2018)
South African coal is mainly used for electricity generation by means of
pulverized fuel combustion and liquid fuels production via indirect
gasification technology and Fischer-Tropsch synthesis. In order to expand
the ...
Sulphur trioxide decomposition with supported platinum/palladium on rutile catalyst. 2. Performance of a laboratory fixed bed reactor
(Elsevier, 2015)
The construction, operation and experimental evaluation of a laboratory scale fixed bed reactor for the decomposition of sulphur trioxide with a supported platinum and palladium based catalyst, were undertaken. The heating ...
