Abstract

Inventia se refera la un procedeu de recuperare a uleiului uzat care cuprinde eliminarea apei si a hidrocarburilor usoare, tratarea termica a uleiului stripat, extragerea lui cu un gaz în conditii supercritice pentru a insolubiliza impuritatile si aditivii, separarea fractiilor bogate în gaze din fractiile de gaze eliberate de ulei, destinderea fractiilor insolubile, separarea aditivilor si impuritatilor, separarea diverselor fractii de hidrocarburi conform vîscozitatilor acestora, comprimarea si reciclarea fazelor gazoase si retragerea reziduului si fractiilor de ulei, conform vîscozitatilor lor.
