CFD modeling of particle charging and collection in electrostatic precipitators
Arif, S.; Branken, D.J.; Everson, R.C.; Neomagus, H.W.J.P.; Le Grange, L.A.; Arif, A. (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 ... -
Development of an integrated model for absorption of sulphur dioxide in limestone slurry
Mchabe, D.; Everson, R.C.; Ramachandran, P.A.; Neomagus, H.W.J.P.; Branken, D.J. (Elsevier, 2021)The aim of this study is to develop an integrated model for SO2 absorption into limestone slurry consisting of four sub-models, namely, absorption of SO2; desorption of CO2; dissolution of limestone and crystallization of ... -
A dual-channel gas chromatography method for the quantitation of low and high concentrations of NF3 and CF4 to study membrane separation of the two compounds
Branken, D.J.; Le Roux, J.P.; Krieg, H.M.; Lachmann, G. (Elsevier, 2013)A dual-channel gas chromatographic method is described in this paper that can be conveniently used for quantitation of NF3/CF4 mixtures with a thermal conductivity detector (TCD) on one channel for the quantitation of ... -
The influence of design parameters on the occurrence of shielding in multi-electrode ESPs and its effect on performance
Arif, S.; Branken, D.J.; Everson, R.C.; Neomagus, H.W.J.P.; Arif, A. (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 ... -
Modelling sorption and diffusion of NF3 and CF4 in Teflon AF perfluoropolymer membranes
Branken, D.J.; Krieg, H.M.; Lachmann, G.; Carstens, P.A.B. (Elsevier, 2014)Molecular dynamics (MD) and grand canonical Monte Carlo (GCMC) simulations with Teflon AF2400 and Teflon AF1600 predicted diffusivities and solubilities of He and N2 that corresponded reasonably with available experimental ... -
Separation of NF3 and CF4 using amorphous glassy perfluoropolymer Teflon AF and Hyflon AD60 membranes
Branken, D.J.; Krieg, H.M.; Lachmann, G.; Le Roux, J.P. (Elsevier, 2014)In this study, the pure and mixed gas permeabilities of Teflon AF2400, Teflon AF1600 and Hyflon AD60 membranes towards NF3 and CF4 were measured to determine whether membrane gas separation can be applied to purify NF3 of ...
