I have really enjoyed the debate guys , But that still doesn't fully answer to my question ? Do you have some detailed examples with hysys on equipement sizing or rating with hysys (shell & tube, vessels and columns), I wd really appreciate it gentelmen !

WELL, THANK YOU APETRI do you have some examples of equipement sizing or rating done with hysys or just with excel ? I want to learn how to do that ? I thought hysys would be a better choice because of its incorporated properties library, isnt it

Hello guys, I would like to design or verify the performances of equipements like heat exchangers, adsorption and distillation towers ? I wonder if I can do that with hysys ? if yes, I will appreciate if you can provide me with some insight ! thanks in advance.

thnx george, I'll have a look on it

Thank you very much, rense ! please, what is the mathematical background needed here ? especially with evolutionary algorithms ? I also wonder if you can tell me what do you mean by compiling ? thank you very much again.

Hello guys, I would like to ask you about "process optimization", a topic that I want to learn, from the basics, as it turned to be an important asset in the field of chemical engineering, so, please: what is the mathematical background I need to have ? can you recommend me some textbooks...

thanx mortenA, this is my first contact with this software, I will try asking on Aspen forums. As for the parameters, they can be estimated through the dynamic assistant. I tried introducin them manually, it helped a little bit, but there might be other parameters that need to be adjusted.

the first step when doing a dynamic simulation is to estimate the cv of the valves and the vesels volumes isn't it ? and that's done either manually or automatically via dynamic assistant, And that's where lays the problem guys, I guess Aspen has introduced a different strategy in V7. I've been...

thnx a lot latexman, this is basically what I did, Every thing was the same, but the results diverged "painfully" !

Hello Every Body, please I would like to ask about the differences in HYSYS V7 compared to older or newer versions, how can I make it give the same results especilally in the estimation of vessels volume, the valves cv ... ? Thank you very much

Thanks a lot guys for sharing all these tips !

Thnx a million Emmanuel,

Hello awsome members of the forum, I am a new member, this is my first participation, I will be assigned soon to an oil and gas treatement facility and I would like to know if there's some blogs/webpages that may enable me to get an insight on the real world problems, for it seems very...
