METHOD FOR CONTINUOUS GREASE MANUFACTURE (D# 74,283-Cl-F) A B S T R A C T A continous process for manufacture of soap thickened grease compositions where a saponifiable material and a metal base are continuously introduced at an elevated temperature into a saponification zone maintained at super- atmospheric pressure and saponified under turbulent condi- tions, wherein the saponified product is mixed with an aqueous solution of oil-insoluble additive materials at a superatmospheric pressure sufficient for maintaining all water in the liquid phase, wherein the saponified material- additive mixture is heated to an elevated temperature of at least 350°F., wherein the heated saponified material addi- tive mixture is flowed into a dehydration zone maintained at a reduced pressure for flash vaporizing substantially all water therefrom and producing a dehydrated saponified material having oil-insoluble additive evenly dispersed therethrough as particles not exceeding about 10 microns, and wherein the dehydrated saponified material is blended with lubricating oil to produce a grease product.
