Classification of distillation operation

According to the operation mode: simple distillation, equilibrium distillation, rectification, special rectification; according to the number of components contained in the raw material: two-component distillation and multi-component distillation; according to the operating pressure: normal pressure distillation, pressure distillation 3. Vacuum distillation under reduced pressure; divided according to operation flow: continuous distillation and batch distillation. A unit operation that partially vaporizes the liquid and uses the difference in volatility of each component to achieve the separation of the mixture. Distillation is a typical unit operation for separating liquid-phase mixtures.
