Air containing 1.6 vol% SO2 is scrubbed at 1 atm with pure water in a packed column

 

Air containing 1.6 vol% SO2 is scrubbed at 1 atm with pure water in a packed column of 1.5-m2 cross-sectional area and 3.5m height, packed with No. 2 plastic Super Intalox saddles. Total gas flow rate is 0.062 kmol/s, liquid flow rate is 2.2 kmol/s, and outlet gas SO2concentration is y=0.004. At the column temperature, the equilibrium relationship is y*= 40x. (a)What is L/Lmin? (b) Calculate NOG and compare your answer to that for the number of theoretical stages required. (c) Determine HOG and the HETP from the operating data.
