I have found an error in the compressibility factor calculation between this version en the older ones. I've been using the peng robinson equation of state and the others results seems to be right. If you know something please write.

Have you spoken to Aspen/Hyprotech? they generally know what errors there are in the program and how to correct them.

PS the latest version of HYSYS is 3.2 now

I agree, send the simulation case to Hyprotech/Aspentch accompanied with a discription of the problem. If you do not want to send the case, at least send a case that contains only the stream in question.
