Amixture of 5mol% butane and 95mol% air is fed to a sieve-plate absorber containing 8 ideal plates at 1 atm and 288.15k.
the absorbing liquid is a heavy, nonvolatile oi. the recovery of butane is to be 95%.
the vapor pressure of butane at 288.15k is 1.92atm.

a)calculate the minimum amount of oil needed for this operation per 100 kmol/h of the gas mixture

b)calculate the amount of fresh oil used in this operation.

c)when the column pressure is increased to 3 atm, calculate the recovery of butane when the same amount of oil in (b) is used.
