Carbon dioxide recovery from the desorption gas of dry gas hydrogen production units
Thread Content
The desorbed gas in dry gas hydrogen production units contains a large amount of carbon dioxide, which would be very valuable if it could be recovered and reused. I wonder if everyone thinks it’s valuable? Among deep cryogenic separation, membrane separation, chemical absorption, and PSA, the latter is the better option as it has lower costs.
If there is a sufficient amount of carbon dioxide, it can be recovered using PSA.
