Question

The exit gas from an alcohol fermenter consists of an air–CO2mixture containing 10 mol% CO2 that is to be absorbed in a 5.0-N solution of triethanolamine, containing 0.04 mol CO2 per mole of amine solution. If the column operates isothermally at 25oC, if 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, use the equilibrium data below to calculate: (a) exit gas composition, (b) moles of amine solution required per mole of feed gas.
