摘要：

In the present work, the group contribution-associating-equation of state (GCA-EOS) is applied for modeling high pressure phase equilibrium of mixtures containing gases and associating fluids. The GCA performance is compared with other group contribution local composition EOS. Based on extensive testing, it is concluded that the GCA-EOS is a reliable method for modeling the extraction and dehydration of alcohols from aqueous solutions using gases at near critical conditions as solvents (dehyextract process). The parameter tables for the GCA-EOS model have been revised and extended. (C) 1997 Elsevier Science B.V.
