Alcohol vapor (0.01 mole fraction) from a carbon dioxide gas stream was removed using absorption process. Water for the absorption contains 0.0001 mole fraction of alcohol. A total of 227 moles of gas are to be treated per hour. The equilibrium relationship for alcohol and water is given by y = 1.0682x. It is required for 98 percent absorption at a liquid rate of 1.5 times minimum.
