What the title states. Is it possible? I can't seem to find a way (at least, from the massive stash of PDF files I downloaded about VLE/EOS) on how to employ NRTL activity coefficients with the Soave-Redlich-Kwong EOS. In other words, is there a way to get the activity coefficient models like NRTL working on SRK? Any help would be appreciated. Thanks~!
