Japanese Patent JPS5242737
Kind Code:
B2
Abstract:
A system of recirculating lubricant palm oil in a cold-strip mill, including an iron remover for separating iron from used palm oil by using sulfuric acid and steam available in the mill, which steam provides heat and agitation for separating the iron as iron sulfates. The system also removes fatty acids in the used plam oil by saponifying them, so as to recirculate iron-free and fatty-acid-free palm oil to the cold-strip-mill.
