The Different Types Of Industrial Distillation

Molecular distillation. In the process of molecular distillation, the path is very short and due to this, the temperature is reduced. Because of the reduction of the temperature, the molecules of vapor are forced to enter the condenser. In this process, some molecules go to the opposite direction of the vacuum and due to the vacuum traps, the
