Benzene is absorbed from air (100 mol/min, 2 mol/min benzene) into wash-oil (50 mol/min) at 100kPa, counter-current. Psat,benzene=50kPa, ideal solution, ideal gas. Neglecting flow-rate changes, the absorption factor, rounded to 2 decimal places, is
1(± 0.1 accepted)
Explanation
m=Psat/P=50/100=0.5. A=L/(mG)=50/(0.5×100)=1.0.
