METHOD FOR REGENERATION OF SPENT LUBRICANTS

摘要

A method for regeneration of spent lubricants by successive treatment thereof with the solution of demulsifier and adsorbent in heating with subsequent separation of purified lubricant. As solution of demulsifier the solution of cationic demulsifier in toluene is used, as adsorbent activated bentonite is used. The purified lubricant is separated by settling with subsequent centrifugation. After the treatment with solution of cationic demulsifier the spent lubricant is centrifuged.
