Exercise 1 MW=200lb/lbmole НС oil L,=L'=? Gas Out A benzene-air mixture is to be scrubbed in a simple countercurrent absorption tower using a nonvolatile hydrocarbon oil as solvent. The inlet gas contains 5% benzene and the entering gas flow is 600 lb moles/hr. Solubility of benzene in oil follows Raoult's law. The tower operates isothermally at 80°F. The average molecular weight of oil is 200 and tower pressure is 1 atm. Plot the equilibrium curve 2 Y2 X2=0.005 Y2 P=1 atm T=80°F R=95% What is the minimum oil rate (Ib/hr) needed to recover 95% of the entering benzene if the inlet liquid contains 0.5% benzene? CgH6-Air y,=0.05 Liquid Out L' V,=600 lbmole/h
