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.

Abstract: A pre-condenser is provided for condensation of water at sub-zero degree Celsius temperatures. A brine solution is cooled below 0 degrees Celsius and delivered to the pre-condenser. The brine solution contacts the vapors and gases from a scrubber, thereby condensing the vapors without allowing ice formation. A vacuum system connected to the pre-condenser removes the remaining gases from a top portion of the pre-condenser while the brine solution and condensed vapors are removed and recycled through a bottom portion of the pre-condenser.
