Carbon disulphide is to be absorbed from a dilute gas mixture of CS2-N2 into a pure nonvolatile oil at atmospheric pressure in a counter current absorber The mole fraction of CS, in inlet gas stream is 0.05 and the flow rate of gas stream, G is 1500 kmol /hr The equilibrium relation is given by y=0.5x, where x is the mole fraction of CS, in liquid stream It is desired to reduce the mole fraction of CS, in the gas stream to 0.005 Calculate the minimum value of L/G, where L is the liquid flow rate in kmol /hr.
