APPARATUS FOR EXTRACTING FATTY ACIDS FROM SOAP STOCK Russian patent published in 2001 - IPC

FIELD: fatty acid extraction equipment. SUBSTANCE: apparatus has reactor 1, ejector 15, pipe 16, filter-bubbler 17, filter 18, vessels 22 and 23, fat catcher 24, separator arranged above reactor 1 and communicated with ejector 15. Separator is made in the form of two-sectioned shell-and-tube heat-exchanger with cooled intertubular space and is equipped with nozzles 9, as well as with head layers 10 and 11. Major part of evaporated acid is brought back to reaction zone due to increased condensing surface, as compared to prior art, and stepped absorption cleaning of discharged vapor-air mixture. Apparatus provides for intensive extraction of fatty acids from soap stock by using chemical reaction with sulfuric acid. EFFECT: increased efficiency and provision for eliminating hazardous outbursts into atmosphere. 1 dwg
