Distillation column is a kind of tower type vapor-liquid contact device for distillation, also known as distillation tower. There are two main types of plate column and packed tower. According to the operation mode, it can be divided into continuous distillation column and batch distillation column. According to the operating pressure: atmospheric pressure, pressure, decompression three. The basic principle of distillation is that the liquid mixture is partially gasified and partially condensed for many times, and the unit operation for separation purpose is realized by taking advantage of the different volatilities (relative volatility, α) of each component. Distillation can be divided into simple distillation, flash distillation, distillation and special distillation.
