<p>A saponification method is disclosed, in which fats and caustic soda are emulsified with 5-10% by weight of recycle liquid soap from the process itself. The emulsion is indirectly contacted with a heating agent in a form divided into plural streams, and is then separated into soap and byproducts comprising glycerine and water. Also disclosed is a saponification reactor comprising a plurality of concentrical tube pairs (31, 32) arranged inside a jacket (33). The saponification reaction mixture is caused to flow through the annular interspaces (36) between each pair of concentrical tubes (31, 32), while steam is caused to flow through the interiors of the innermost tubes (32) in each pair and through the jacket space between the outermost tubes (31). <IMAGE></p> |
