1. The exit gas from an alcohol fermenter consists of an air- CO2 mixture containing 10mol% CO2 that is to be absorbed in a 5.0- N solution of triethanolamine, containing 0.04mol of carbon dioxide per mole of amine solution. If the column operates isothermally at 25C the exit liquid contains 78.4% of the CO2 in the feed gas to the absorber, and if absorption is carried out in a six-theoretical plate column, calculate: (a) Moles of amine solution required per mole of feed gas L/VN+1. (b) Exit gas composition. Equilibrium Data Y= moles CO2/ mole air; X= moles CO2/ mole amine solution 1.
