Ethyl alcohol is absorbed from an inert gas stream using pure water at 303 K and 101.3 kPa. The gas stream flow rate is 100 kmol/h and it contains 2% alcohol. We wish to recover 92% of the alcohol. The equilibrium relationship is given by y=0.68x for this stream. Using 1.5 times the minimum liquid flow rate, determine the number of trays needed using: (a) Graphical methods; (b) Analytical methods.
