ABSTRACT:
The present invention provides a method and apparatus for the recovery of salt from a glycerine process, allowing the salt to be used in a brine solution. A salt settling tank is positioned inline between the foots from a crude still bottom and a foot still. Salt settles to the bottom of the settling tank and into a salt receiver positioned below, while clarified liquid overflows to the foot still. Salt from the salt receiver is then semi-continuously transferred into a salt extractor where the salt is removed from the mother liquor. A condensate is then circulated into the salt extractor and the salt slurry is then stored in a brine storage tank.
