Purification of carbon dioxide for reactor purposes. Part II - pressure losses through packed beds of selected desiccants

Abstract

Pressure losses have been measured for the flow of carbon dioxide, air, argon, helium, hydrogen and methane through beds of molecular sieves, and for carbon dioxide and air through beds of activated alumina. It is shown that at the levels of moisture impurity expected in the Australian H.T.G.C. reactor no increased pressure loss caused by adsorption should be encountered. The effect of temperature was studied but in all cases found to be slight. Generally, good correlations were obtained although the low molecular weight gases, particularly hydrogen, showed considerable deviation.
