The first book of its kind on the distillation industry, the practical lessons it offers are a must for those seeking the elusive path to trouble-free distillation. Distillation Troubleshooting covers over 1,200 case histories of problems, diagnoses, solutions, and key lessons.

the operating line is the solution (answer) of the material balances (this plot is called “McCabe-Thiele diagram”) for the flash distillation, as the intersection of the equilibrium line (curve) and the operating line is the point where the system (i.e. the flash tank) reaches the equili-brium Note also that when i y = i x (or i x = i y

Distillation Distillation is a commonly used method for purifying liquids and separating mixtures of liquids into their individual components. Familiar examples include the distillation of crude fermentation broths into alcoholic spirits such as gin and vodka, and the fractionation of crude oil into useful products such as gasoline and heating oil.

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.

The computer solution of a binary distillation problem by the McCabe-Thiele method utilizes the equations of Lewis and Sorel which when drawn upon the y - x diagram of vapor-liquid concentrations, are the operating lines of the McCabe-Thiele method. The equilibrium data required is input as a series of paired values of x and y.

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%

Since it is proven that residue curves are solutions to the gradient system with respect to the boiling temper- ature (Shcherbakova et al., ), the stable 

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
