PROCESS FOR THE RECOVERY OF OILS FROM A SOLID MATRIX

摘要

Process for the recovery of oils from a solid matrix comprising: subjecting said solid matrix to extraction by mixing with at least one organic solvent having a boiling point lower than or equal to 160°C, preferably ranging from 60°C to 140°C, operating at a temperature ranging from 5°C to 40°C, preferably ranging from 15°C to 30°C, and at atmospheric pressure (1 atm), obtaining a solid- liquid mixture; subjecting said solid-liquid mixture to separation, obtaining a liquid phase comprising said oils and said organic solvent and a solid phase comprising said solid matrix; recovering said organic solvent from said liquid phase.
