More often problems in distillation columns are associated with changed circumstances - changed operating conditions or changed product specifications - or in the extreme a changed duty to effect a different separation. Whatever gave rise to the problem the distillation column is not achieving the required separation and/or capacity.

Distillation 4.1 Vapor Liquid Equilibrium Relations The equilibrium in vapor-liquid equilibrium is restricted by the phase rule. For a binary mixture in two phases, the degree of freedom F is given by F = m − π + 2 = 2 − 2 + 2 = 2 (4.1-1) As an example we will use the benzene-toluene, vapor-liquid system. The four variables are

Multicomponent Distillation Example Problem A liquid feed stream at 2 atm and 298 K produced from mixing together a stream from a catalytic reforming unit and a stream from a toluene trans-alkylation unit contains benzene, toluene, o-xylene, m-xylene, and p-xylene at mole fractions of 0.34, 0.33, 0.11, 0.11, and 0.11, respectively.

W = F - D = 50 mol. Slope of the operating line = -W/D = -1. With these data, the equilibrium curve and operating line for flash distillation are plotted as follows: From the plot, it could be seen that the operating line cuts the equilibrium curve at the point (0.31, 0.69). That is yD = 0.69 and xW = 0.31. Composition of top product = yD = 69%

Sample Problem # 1 A liquid mixture containing 45% benzene and 55% toluene is being distilled such that 95% of the benzene appears in the distillate and 90% of the toluene remains in the bottom. Determine the composition of the two product streams.

The optimal solution for distillation sequence synthesis problems was found in 1,723 CPU s for a ternary mixture and 2,470 CPU s for a quaternary mixture. As the models are written in an EO environment ACM for inner level simulation and connected to Python for outer level optimization, data transfer time between the software consumes at least
