It is desired to separate methanol (CH3OH) from methanol-water mixture in a sieve plate column operating at 2 atm, 83.2 °C (methanol boiling point at 2 atm), and 80% of

the flooding velocity. The spacing of the trays is 600 mm and the vapour and liquid flow rates are 650 kmol/hrand 2750 kmol/hr, respectively. Assume ideal gas law, the density of water as 1000 kg/m and that the vapour is entirely methanol and liquid is entirely water. Calculate the liquid-vapour flow factor
