In stage-by-stage distillation calculation, we step off the stages up the column until the composition becomes equal or lower than the desired top product composition True False The optimum location of the partial condenser is at the intersection of the operating and feed lines True False The temperature of the superheated vapor feedi: the dew-point temperature. less than higher than equal to The number of stages required for a binary distillation column can be determined using mainly McCabe-Thiele method. Ponchon-Savarit method. external column balance method. A distillation column with two feeds F1 and F2. The composition of the MVC for F1 is 0.45 and 0.50 for F2. The plate location for F2 is expected to be than for Fl. lower than similar to higher than i The enthalpy of the superheated vapor feed is less than. higher than. equal to. that of saturated vapor
