Hi,
I'm currently attempting to model a PSA column to separate hydrogen from CO2,N2,O2,CO but I can't seem to find an adsorption unit in HYSYS .
Is this possible or should I use another program?
Cheers

good luck

peng-eng,
When someone is normally building a simulation model, there is an end objective. For example, if you are building an exchanger model, maybe you want to find out the duty, or it fouling etc. In your PSA column, what are you trying to calculate? A PSA unit does not normally consume energy as such.
If the PSA in the process (which you are trying to simulate) is a purification step, you can make use of the spreadsheet to calculate the downstream composition (based on the PSA feed stream composition) and let that carry onward as a feed stream to your downstream process.
Are you trying to calculate some other parameter?

I'm trying to model a purification step, I've decided to use a component splitter instead to simplify matters.
