Conversion of calcium sulphide to calcium carbonate during the process of recovery of elemental sulphur from gypsum waste
De Beer, M.; Liebenberg, L.; Maree, J.P.; Doucet, F.J. (Elsevier, 2014)The production of elemental sulphur and calcium carbonate (CaCO3) from gypsum waste can be achieved by thermally reducing the waste into calcium sulphide (CaS), which is then subjected to a direct aqueous carbonation step ... -
Experimental investigation of the effective thermal conductivity in the near-wall region of a packed pebble bed
De Beer, M.; Du Toit, C.G.; Dreyer, H. (SACAM, 2016) -
Experimental study of the effective thermal conductivity in the near-wall region of a packed pebble bed
De Beer, M.; Du Toit, C.G.; Rousseau, P.G. (Elsevier, 2018)The effective thermal conductivity is an important parameter that represents the overall heat transfer in packed beds, including packed pebble beds. Experimental test facilities have been used to determine the effective ... -
A methodology to investigate the contribution of conduction and radiation heat transfer to the effective thermal conductivity of packed graphite pebble beds, including the wall effect
De Beer, M.; Du Toit, C.G.; Rousseau, P.G. (Elsevier, 2017)The effective thermal conductivity represents the overall heat transfer characteristics of a packed bed of spheres and must be considered in the analysis and design of pebble bed gas-cooled reactors. During depressurized ... -
A review of methods to predict the effective thermal conductivity of packed pebble beds, with emphasis on the near-wall region
De Beer, M.; Du Toit, C.G.; Rousseau, P.G. (Elsevier, 2018)The effective thermal conductivity is an important parameter that is representative of the overall heat transfer in a packed bed of spheres. It includes the effects of conduction through the solid material and contact areas ...
