Methods of calculating engineering parameters for gas separations

D.D. Lawson

Applied Energy, 1980, vol. 6, issue 4, 255 pages

Abstract: A group additivity method has been generated which makes it possible to estimate, from the structural formulas alone, the energy of vaporisation and the molar volume at 25°C of many nonpolar organic liquids. From these two parameters and appropriate thermodynamic relationships it is then possible to predict the vapour pressure of the liquid phase and the solubility of various gases in nonpolar organic liquids. The data are then used to evaluate organic and some inorganic liquids for use in gas separation stages or as heat exchange fluids in prospective thermochemical cycles for hydrogen production.
