components %Volume
of the gas
H2 51.8
methane 13.0
ethane 14.0
propane 11.0
butane 6.0
pentane 1.0
H2S 3.2
I need to design an absorber (38C and 4bar) to seperate H2S from this gas using DEA. I think H2S is the heavy key -%vol 0.04 H2S at top product- but i dont know what is the light key.
To draw McCabe i need relative volatility but i dont know how to find K values for relative volatility. I dont know Yi and Xi values so im looking for a different way to calculate K. After that i will need a stripper to seperate amin and H2S but i couldnt find relative volatility for these too.
Is there information about this components in Aspen Hysys. I have heard something like that but couldnt find anything.
