The overhead system for a distillation column is shown in Figure. The composition of the total distillates is indicated, with 10 mol% of it being taken as vapor. Determine the pressure in the reflux drum, if the temperature is 100?F. Use the following K-values by assuming that K is inversely proportional topressure.

$Vapor distitlate cw Total distillate Component mole fraction 0. 10 0.20 0.70$

Vapor distitlate cw Total distillate Component mole fraction 0. 10 0.20 0.70 100 100 F Liquid distillate
