Abstract
A method of processing glyceride fats to produce fatty acids and glycerin comprises subjecting preheated water and preheated fat to continuous high temperature, high pressure hydrolysis and continuously subjecting the sweet water issuing at high temperature and high pressure from the hydrolysis to multiple stage vaporization without the application of extraneous heat to produce crude glycerin in concentrated form, this multiple stage treatment including an initial expansion stage to a super-atmospheric pressure below that at which the countercurrent hydrolysis is performed, a final expansion stage to a subatmospheric pressure, and at least one intermediate expansion stage to an intermediate pressure, part of the heat contained in p the vapours from each stage except the last being employed to heat the liquid in the succeeding stage. The fatty material entrained in the resulting crude glycerine may be separated out by gravity settling, centrifuging, or other convenient means, whereby crude glycerine suitable for distillation is produced. Apparatus is described in which the glycerin is concentrated from sweet water to crude in four successive expansion stages. Specification 617,929 and U.S.A. Specification 2,156,863 are referred to.
