3 Since the number of specified variables (8) is equal to that of the degrees of freedom (8), the problem can be solved, which means that we can draw all operating lines and the feed line(s) step off stages - to find the number of equilibrium stages required for that problem For a ternary (3-component) mixture, the degree of freedom is 3 + 6 = 9 Thus, we need to have 9 specified variables to

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.

Thermische Verfahrenstechnik I binary distillation Binary distillation Using a tray column, a binary mixture with components A and B has to be separated by distillation. The feed F with x F,A is a two phases stream with 50% vapor. It is separated into three parts: - a distillate stream D with y D,A (vapor) - a bottom stream B with x B,A

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%

However, many smaller steps in the distillate flow rate parameter were needed to negotiate the turning points at D = 28.468kmol/h and D = 30.623kmol/h and locate the intermediate and high purity solutions. Continuation from the intermediate solution gives essentially the same results. 6.

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.
