Experiments show that on a broad range of molecular weight materials, a relationship exists between the molecular weight and the distillation temperature of the material. There is no predictable temperature at which distillation will occur; condensation begins whenever a sufficient temperature differential occurs between evaporator and condenser.

Difference Between Evaporation and Distillation

Difference Between Evaporation and Distillation

Feb 24, 2017 Distillation involves vapour formation at the boiling point of the liquid and is a rapid process compared to evaporation. Evaporation occurs at the surface of the liquid whereas distillation occurs with the boiling of the bulk of the liquid. This is the difference between evaporation and distillation. 1.

How Molecular Distillation Occur ; Sulfates - Lenntech. Distillation is a water treatment system in which water is boiled, and then the steam is cooled until it condenses into a separate container. The dissolved substances, such as sulfate, remain in the boiling pot. If operated properly, distillation units can remove nearly 100% of sulfate.
