Hello
I wish to design a unit by HYSYS and I need some help. I want one or more distillation column to extract etylen from dry gas of FCCU but feed stream contain noncondenceable gases ( 1.13% H2, 5.51% CO2 and 11.88% N2 ) and so I want remove these gases first.
Is there any kind of absorber for this mean? Or is there any specific type of tower?
P.S. the feed stream components are as below: (numbers are wt%)
H2 1.13
CO2 5.51
N2 11.88
C1 25.59
C2 18.53
C2= 22.9
C3 0.68
C3= 5.48
IC4 0.54
NC4 0.18
C4= 7.47
IC5 0.11
