one lbmole/hr of a gas mixture consisting of 75mole% methane and75mole% of n-pentane at 80F AND 1 atm is to be scrubbed with 2 lbmole/hr of a nonvolatile paraffin oil of molecular weight 200, heat capacity 0.45BTU/(lbmass)(F) entering a 3 equilibrium-stage absorber free of pentane at 95F.How do I compute 1)the exit mole fraction of pentane from each stage in both phases;the liquid and gas flow rates (in lbmole mixture/hr) from each stage; and the equilibrium temperature of each stage2)the fractional (or%) absorption of pentane attained the absorberData:constant temperature average pure component heat capacities:methane:8.5 BTU/(lbmole)(F)n-pentane:28.6 BTU/(lbole)(F) as vapour, 42.4BTU/(lbmole)(F) as LiquidLatent heat of vaporisation:n-pentane:12,500BTU/lbmole at 0F
