mixed oil alkali refining in oil production line


Alkali Refining - Lipid Library - AOCS

Two processes have been developed for the refining of edible oils and fats, i.e. physical and chemical refining; the In the edible oil industry almost only caustic soda is used for this reaction, but potassium hydroxide is also used by a few producers. Additional filters incorporated in the process line are merely intended to retain impurities in order to prevent damage to pumps The concentrated caustic soda and dilution water are mixed in a static mixer before being added to the oil.
