Deodorization

Deodorization is a vacuum stripping process in which a given amount of a stripping agent (usually steam) is passed for a given period of time through hot oil at a low pressure. Hence, it is mainly a physical process in which various volatile components are removed. However, since it is usually carried out at high temperature (220 to 250°C), some chemical, thermal effects may take place as well.

Salient features:

• Most efficiently designed oil to oil heat exchanger fitted in last tray of Deodorizer ensures minimum heat energy requirement.
• Elaborate and efficient design of fatty acid scrubbing recovery system ensures virtually no carry over fatty acid into barometric condenser.
• Most efficiently designed heating coil which prevents to charring of oil during the process
