My case is to find which thermodynamical properties EXACTLY uses when it calculates a block. So I searched a lot, I studied documentations, manuals but nothing. Is there anybody who can help me? Thank you all..

Hello Guys I am a post graduate student currently carrying out a process design and optimization research on the multistage separation. However I would require the Aspen hysys software. I would be most grateful if any one could assist me with this. Thanks

I see several years ago the source code from the designers (Canadian people), I reccomend you read the book "chemical process computations" raghu raman and unifac from fredeslund book, an other book to undestand the distillation and some separation read the book "calcul sour ordenatieur des équilibres liquide-vapour et liquide-liquide" Henry renon, for reactors they use several technical publication from Canadian chemical eng, I hope this will be helpfull to you. best regards
