The vapor containing 70 mole% methanol (and remaining 30 mole% water) from the top tray of a methanol distillation column enters a partial condenser at a rate of 70 kmol/hr at 1 atm pressure. Note that you would have to solve parts (a) and (b) independently. You can use the same x-y equilibrium diagram shown in Figure 1 for both (a) and (b). (a) If 30% of the vapor is condensed, calculate the composition of the uncondensed vapor stream. Also, estimate the composition of the condensed stream. (b) If uncondensed vapor leaving the partial condenser has a composition of 90% methanol, estimate the flow rates of the condensate and uncondensed vapor. Also, estimate the composition of the con- densate. 1.00 y = x 0.90 0.80 0.70 0.60 y [-] 0.50 0.40 0.30 0.20 0.10 0.00 0.00 0.20 0.40 0.60 0.80 1.00 x[-] Figure 1: x - y equilibrium diagram for methanol- water at a pressure of P = 1 atm (for Problem 1) (x and y denote the composition of methanol in liquid and vapor phases respectively)
