Glycerol Evaporation


Natural glycerin is obtained primarily as a co-product from the production of fatty acids and fatty esters, or soap from oils and fats. Sweetwater or glycerin obtained as a co-product from other processes contains impurities and must undergo further purification and concentration, for example, by evaporation.

Vaisala K-PATENTS® Compact Refractometer PR-43-GC is used to measure the glycerin concentration in evaporation. Automatic control of the evaporator is possible by using the refractometer’s output signal.
