Thank you for your reply R_RAZI.
I understand that for anything above 15% molecular sevies are a good option and it is the only option for offshore production platforms.
Yes the CO2 content is less than 15% as of now.

But I was trying to do a economic and HSE comparative between Amines and Sevies.
More in the lines of cost of operating them and maintaining them etc.
I am looking for a cheaper option.
