1. A packed tower is designed to recover 98% CO_(2)’from a gas mixture containing 10%’CO_(2)’and 90% air using water.Y=14 X can be used for equilibrium conditions where Y is kg’CO_(2)’/kg dry air and X is kg’CO_(2)’/kg water.The water to gas rate is kept 30% more than the minimum value.The height of the tower if HTU is 1 metre will be
