Hi, I am a new member I really need your help in hysys programme
In my project I have three reactions one of them is equilibrium reaction and the others is conversion reactions. and hers the problem, we cannot mix these two types of reactions in one set and the reactor cannot accept more than one set. I just thinking about separate them into two reactors and then mix the products!!
I have no idea if it’s right or wrong; if anyone knows how to do it please help me
thanx

Depends on the reactions themselves. If they are consecutive, you could use different reactors in series. If they are parallel reactions, you might try using a "Tee" operation and split the streams between two different reactors arranged in parallel, and with a split ratio equivalent to relative rates of these reactions. This is just a wild guess, I never had an opportunity to try something similar, and I don't know if it can work in your case. You might give it a try?

Good luck,

Dear,
Yes the reactor will not accept the two sets but can accept two reactions (similar). In your case the two conversion reactions you can attach to a single reaction set. Don't get confused about the reactions and the reaction set. The reaction is one and the reaction set could have the multiple reactions, e.g. you have an oxidation reaction which will have partial and total oxidation (complete oxidation or the combustion) now these two reaction yield different products but the reaction happens in the same reactor. So configure the different reactions and add the similar reaction to a reaction set (by defualt in Hysys there is one Globle Rxn Set) you can have multiple reaction sets with multiple reaction in one set. And give ranking to the reaction in the set if your set has multiple reactions. Make sure that only similar reactions can be put to a reaction set like conversion reactions. And its quite clear that an equilibrium and conversion reaction can't occur together. There are different templates (reactor modules) which we have to use. I hope this would solve your query if you need further assistance plaease let me know else you define your problem here in details and wait that I will give you the steps for how to configure and run the simulation waiting for your comments.

thank you very much for your help
i solve it
