ABSTRACT:
A method is provided for cleaning parts soiled with oil components and seating terpenes from oil compositions using filters having suitable pore sizes to allow terpene components to pass through the walls of the filter as a permeate while not allowing oil components to pass therethrough. A separate aspect of the present invention utilizes a ceramic filter capable of separating water components from a mixture of terpenes and oil, thus allowing filtered water to be reused in a cleaning procedure. Using both types of filters in one operation provides a substantially closed loop recycling system where terpene components can be reused to clean additional articles, water can be reused to rinse such articles and contaminants removed in the cleaning process can be either reused or disposed of.
