Dear frnds, i have to design scrubber for CO2 absorption using caustic solution. i have calculated the dia and height of packing by calculation. I want to simulate the calculated data using aspen to varify the calculated data. I have searched many site for step by step instruction for absorber simulation using aspen but i got only for physical absorption not for chemical absorption. is anybody having any guide lines or books please upload or suggest any referrence books regarding using aspen.

thank you.
