DISTILLATION

Introduction. Distillation is the most widely-used method of separating fluid mixtures on a commercial scale, it is thus an important part of many processes in the oil and chemical industries. Many of the tall, thin towers which may be seen in an oil refinery or chemical plant are distillation columns. The most common column diameter is about 2

Distillation - Definition, Detailed Process, Types, Uses

Simple distillation involves heating the liquid mixture to the boiling point and immediately condensing the resulting vapors. This method is only effective for mixtures wherein the boiling points of the liquids are considerably different (a minimum difference of 25 o C). The purity of the distillate (the purified liquid) is governed by Raoult

Separation processes - processdesign

23/2/2016· Flash Distillation is one of the simpler separation processes to be employed in a chemical plant. The main premise of flash distillation is that a portion of a liquid feed stream vaporizes in a flash chaer or a vapor feed condenses. Vapor-liquid equilibrium will cause the vapor phase and the liquid phase to have different compositions.
