Question
The gas leaving an alcohol fermenter consists of 10% CO2
and 90% air.
80% of CO2
in the gas is to be recovered by absorbing in an amine solution
containing 0.01 mole CO2 per mole of CO2
free amine solution. Amine is
supplied 40% in excess of the minimum. 100 kmol/h of gas enters the
counter-current absorber.
Find the mole percentage of CO2
in the exit liquid.
The equilibrium data at the operating condition is given below.
