A packed tower is to be designed to recover 98% CO2 from a gas mixture containing 10% CO2 and 90% air using water. A relation y = 14x can be used for equilibrium conditions, where y is kg CO2/kg dry air and x is kg CO2/kg water. The water-to-gas rate is kept 30% more than the minimum value. Calculate the height of the tower if HTU is 1 meter.
