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&#xb0; C., preferably ranging from 60&#xb0; C. to 140&#xb0; C., operating at a temperature ranging from 5&#xb0; C. to 40&#xb0; C., preferably ranging from 15&#xb0; C. to 30&#xb0; 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.

Process for the recovery of oils from a solid matrix

The present invention relates to a process for the treatment of oil residues coming from the oil industry which comprises the recovery of the oil fraction of residues by extraction with solvents having a low environmental impact (ethyl acetate/toluene) and subsequent finishing for the downgrading of the residual material.

The present invention relates to a process for treatment of soils polluted by high-boiling organic substances, such as petroleum, polynuclear aromatics and chloro-organic substances, which process uses an extractant with high dissolving power for the pollutant, and which improves the soil-extractant contact thanks to the addition of a minimal amount of a hydrophilic co-solvent.
