Hello everyone,
I just want to ask you, i have to simulate co-current Absorber in Aspen Plus for flue gas cleaning. I am using currently RadFrac, namely Absorber 2 Model in Aspen Plus. But it seems, as if that all Absorber model in Aspen Plus is only for counter-current flow.
What i did, for example, i specified there are 5 stages in the column, with no reboiler and no condenser. I also specified that the feed gas and feed liquid enter the 1st stage, and the product streams for gas leaves the column at 4th stage, meanwhile the liquid at 5th stage. But then, Aspen requires me to Input a stream to the bottom stage, since i introduced all feed streams in the top stage.
So, is it true, that we can not model Absorber with co-current flow in Aspen Plus? Has anyone had experience with co-current Absorber in Aspen Plus?
Thank you for your reply and sharing.
Best Regards,
Ikha
