Abstract
1468092 Recovering fatty substances APOTHEKERNES LABORATORIUM FOR SPECIAL-PRAEPARATER AS 6 Aug 1974 [28 Jan 1974] 34670/74 Addition to 1468091 Heading C5C Fatty substances are recovered from aqueous effluents as described in the parent Specification but in addition the stabilized sludge containing the stabilized fatty substance or degradation product thereof is acidified so that it separates into an upper concentrated fatty sludge phase and a lower aqueous phase. The acids used may be hydrochloric acid or soap stock (as defined). The upper fatty sludge phase is separated from the aqueous phase and the former is heated to form an upper phase containing technical fatty acid and a lower aqueous phase containing the precipitation chemicals used to precipitate the original stabilized aqueous fatty sludge, these two phases then being separated.
