Short Path Distillation The short path evaporator combines thin film evaporator and con-denser in a single apparatus. The vapours are condensed on the built-in condenser. The product path between the evaporation and condensation is extremely short, therefore, the pressure drop is low. Advantages Wiped Film Distillation

Thin film evaporators from laboratory to production scale

In a wiped film evaporator or a thin film evaporator, a rotating wiper system distributes the crude product to a film on the inner surface of a heated pipe. The wiping system speeds up the evaporation process by keeping the product film turbulent so that the heat transfer and mass transfer are optimized.

Fractional Distillation - The Complete Guide [New in 2019]

Jul 30, 2019 · Vapor Pressure This is defined as the pressure created by a vapor in equilibrium with its liquid phase at a given temperature in a closed system, such as a distillation apparatus. Once this pressure rises to the same level as the ambient pressure in the system, bubbles are stable in the liquid, and it will start to boil.

Thin Films | SpringerLink

Minor differences between the compositions of the film and target do still occur, but are normally the result of oxidation or of the evaporation of one component at high temperatures. When compounds are sputtered the incident ion energies are often sufficient to break the chemical bonds, again leading to a deficiency in one component.

Vacuum distillation by wiped film and short path evaporators

In wiped film and short path evaporators, the crude material is heated up on the internal surface of a heated tube. A special rotating wiping system inside the evaporator is generating a very thin and turbulent film on the heated surface. Out of the heated and thin film, the evaporation of the light boiling component takes place.
