Example 12-3. Graphical analysis for more concentrated absorber
A gas stream is 90mol%N2 and 10mol%CO2. We wish to absorb the CO2 into water. The inlet
water is pure and is at 5C. Because of cooling coils, operation can be assumed to be isothermal.
Operation is at 10atm. If the liquid flow rate is 1.5 times the minimum liquid flow rate, how many
equilibrium stages are required to absorb 92% of the CO2? Choose a basis of 1molh of entering gas.
