MCQOPTIONS

1.	Acetone is to be removed from air in an isothermal dilute absorber using pure water as solvent. The incoming air contains 5 mole% of acetone (y in = 0.05). The design equation to be used for obtaining the number of trays (N) of the absorber is, N+2 = 6 log (y in /y out ).For 98% recovery of acetone, the number of trays required is/are
