Abstract:
A process for reconditioning oil comprising the steps of continuously and sequentially;a. charging contaminated oil at a flow rate in the range of about 4 to about 10 gallons per hour and at a pressure in the range of about 20 to 100 psi to a filter zone;b. filtering said contaminated oil in said filter zone to separate therefrom particulates having particle sizes over about 1 to about 5 microns;c. depositing said filtered oil upon an upper central surface region of a generally dome-configured platen so that a thin film of said filtered oil is formed on said platen and flows generally radially outwardly and downwardly over surfaces of said platen while said platen is heated to a temperature in the range of about 160 to about 200.degree. F. so that volatiles are separated from said thin film; andd. collecting said separated volatiles in a chamber existing over said platen surfaces but under said filter zone while concurrently collecting oil from said thin film from lower peripheral regions of said platen.
