Title: Method and equipment for removing impurity in oil
Inventor: YANO AKIHIKO
IPC: C10N40/25
Filed: 1995-03-30
Abstract: PURPOSE: To ensure removal of impurities as fine as at most several μm in particle diameter contained in an oil by mixing a system oil with an oil-soluble solvent having an ester linkage to form coarser particles of impurities, removing them and then distilling off the solvent. CONSTITUTION: For removing impurities contained in a system oil used for lubricating, e.g. an internal combustion engine, the oil is mixed by, e.g. agitation with an oil-soluble solvent having an ester linkage in the molecule to form coarser particles of the impurities. The obtained coarse particles are removed by, for example, a centrifugal separator, and the solvent is then distilled off from the oil, thus accomplishing the removal of the impurities from the oil. This technique ensures the removal of impurities as fine as at most several μm in particle diameter contained in a system oil. The use of a distiller for removing the solvent permits the reuse of the solvent so that low-cost removal of impurities in an oil can be realized.
