One hundred kilogram-moles per hour of a feed containing 30 mole% n-hexane and 70% n- octane is to be distilled in a column consisting of a partial reboiler, a theoretical plate, and a partial condenser, all operating at 1 atm (101.3 kpa). the feed, a bubble-point liquid, is fed to the reboiler, from which a liquid bottoms product is continuously withdrawn. bubble-point reflux is returned to the plate. the vapor distillate contains 80 mole% hexane, and the reflux ratio (lrd) is 2 assume the partial reboiler, plate, and partial condenser each function as an equilibrium stage. (a) using the mccabe-thiele method, calculate the bottoms composition and moles of distillate produced per hour.
