1. A liquid solvent (C) is used to selectively absorb a gaseous contaminant (A) from its mixture with an inert gas (B). The equipment is a packed absorption column, which receives 200 kmol/h of feed gas mixture containing 10% contaminant. The effluent regulation on the gas phase requires that 65% of the contaminant must be removed. The fresh liquid solvent is fed at a rate of twice the minimum required flow rate in kmol/h. The contaminant equilibrium solubility information is given as y* = 0.6x", where x and y are contaminant mole fractions in liquid and gas phases respectively. Assume lean-gas problem conditions and calculate the number of transfer units Noy for the packed tower. Va
