please show all your working because this calculation does require a few steps and i want to understand how you got the answers, do not use chat gpt or AI please, that solution will be down voted. Thanks. An effluent gas from a refinery with composition $C{H}_4,C_2{H}_6,C_3{H}_8$ and $C_4{H}_{10}$ is fed into

an absorber to reduce the propane content of the effluent before recycling. The

absorber operated at $37C$ and $400$ kPa $($abs$).$ The entering oil and gas with its

composition is shown in the following table. The absorber has $4$ theoretical stages.

Do one iteration to determine the liquid and gas flow rates of all the

components.
