Question

Can someone help with this separations problem?

sol- A complete gas treatment plant often consists of both an absorber to remove ute from air and a stripper to regenerate solvent. Some treated air is heated and is used as stripping gas. In a particular application we wish to remove obnoxious impurity from inlet air. Absorber operates at 1.5 atm and 24.0°C where obnoxious impurity equilibrium is given as y ates at 1.0 atm and 92.0 C where equilibrium is y 3.0x (units are mole fractions). Total feed air flow rate is 1400.0 mol/day, and feed gas is l50 mdł% obnoxious impurity, and the remainder is air. We desire a treated air concentration of 0s mol % obnoxious impurity Liquid flow rate into the absorber is 8000 mol day, and D3 0.5x (units are mole fractions). Stripper oper-
