The main advantages of rectification are that the system can be operated continuously and that the separation effect is many times greater than that of a simple distillation. The reason for this lies in the several countercurrent contacts of the vapour with the liquid. Therefore, rectification is preferred to sequential single distillations. | The main advantages of rectification are that the system can be operated continuously through the refluxes and that the separation effect is many times greater than that of a simple distillation.
