Institut Francais du Petrole des Carburants et Lubrifiants et Entreprise de Recherches et d Activities Petrollieres Elf, Millen Raptes & White, November 9, 1976: US03990963 (22 worldwide citation)

Used lubricating oils are first heated to 200.degree.-500.degree. C, optionally with added steam, and then filtered through a membrane such as an ultra-filtration membrane. The latter has preferably a cut range of from 5,000 to 300,000.
