Question 1 (Total = 10 marks) A packed column is designed to recover acetone from air by a counter current pure water at 60F and 0.35ft2 area. The air contains 3mol% acetone at the inlet, and 0.09 mol\% acetone at the exit. The inlet gas flow rate is 7.916lbmole/h at 60F,1atm and the xy equilibrium relation is: Y=1.75X Obtain: (a) is the process absorption or stripping? (2 marks) (b) minimum water rate in lbmole/ft2h. (5 marks) (c) calculate the equivalent Height of Theoretical Unit (HTU), if the overall mole capacity coefficient, is 12Ibmol/(ft3.h. y)
