A tray tower to be designed to absorb SO2 from an air stream by pure water at 293 K. The entering gas contains 20 mol% and leaving 2 mol% at total pressure of 101.3 kPa. The inert air flow is 150 kg air /hr and the entering water flow is 6000kg water/hr. Assume the efficiency of 50% ,how many theoretical and actual trays needed .What are the environmental risks of SO2
