Abstract:
1. A process for the recovery of oils, the process comprising: extracting a solid matrix by mixing the solid matrix with at least one organic solvent having a boiling point lower than or equal to 160° C., such that the extracting occurs at a temperature ranging from 5° C. to 40° C. and at atmospheric pressure (1 atm), to obtain a solid-liquid mixture; separating the solid-liquid mixture to obtain a liquid phase, comprising oils and the at least one organic solvent, and a solid phase comprising the solid matrix; adding an electrolyte to the liquid phase in a quantity ranging from 1% by weight with respect to a total weight of said liquid phase to a solubility limit of the electrolyte in the liquid phase; and recovering the at least one organic solvent from the liquid phase.
