A tray tower is absorbing ethyl alcohol from an inert gas stream using pure water at 303K and 101.3kPa, the inlet gas stream flowrate is 95 kamol/h and it contains 3 mol % alcohol. The equilibrium relationship is y-1.2x for this dilute stream. Using 1.5 times the minimum liquid flowrate determine the number of trays needed (a) graphically, (b) analytically.
