A 1-ft diameter packed column is used to scrub a soluble gas (MW = 22) from an air-gas mixture. Pure water enters the top of the col- umn at 1000 lb,/tr. The entering gas stream contains 5% soluble gas and 95% air. Ninety-five percent of the soluble gas is removed. Both the operating line and equilibriam curve may be assumed to be straight, The equation for the equilibrium curve is y = 1.2x, where x, y = mole fractions. The entering gas mixture iow rate is 800 lb,„/hr. The column operates at 30 °C and 1 atm, and k,a = 12.0 lbmol/hr-ft-Ay ka = 8.0 lbmol/hr-ft-Ar O = 1.0

Calculate or find:
Concentration of the soluble gas in the effluent liquid if the column is operated at minimum liquid flow rate
