Distillation is the operation of multiple and simultaneous use of partial vaporization and partial condensation to completely separate the mixture and obtain nearly pure components.
Distillation is the operation of multiple and simultaneous use of partial vaporization and partial condensation to completely separate the mixture and obtain nearly pure components.
Process: In the distillation tower, the liquid with relatively low temperature flows from top to bottom under the action of gravity from the top of the tower, while the gas (steam) with higher temperature flows from bottom to top under the action of pressure. When the two meet, the gas phase partially condenses and the liquid phase partially vaporizes, thus achieving multiple partial vaporization and multiple partial condensation at the same time. Distillation equipment is a distillation method that uses reflux to separate liquid mixture with high purity. It is a widely used liquid mixture separation operation in industry, and is widely used in petroleum, chemical, light industry, food, metallurgy and other departments.
