ABSTRACT OF THE DISCLOSURE Petroleum fractions may be separated into aromatic-rich and paraffinic-rich hydrocarbon streams by the use of methanol/water mixtures having more than 20% water. The paraffinic-rich stream is recovered as raffinate. The aromatic-rich stream passes out of the extraction zone and is recovered by lowering the temperature to induce a phase separation.
