| titleOfInvention | Energy efficient aromatic extraction process |
| abstract | ENERGY EFFICIENT AROMATIC EXTRACTION PROCESS ABSTRACT The process for the dearomatization of a mixed hydrocarbon feed which comprises the following steps: (a) contacting said feed in an extraction zone at a temperature of at least about 150°C with an aromatic extraction solvent to provide a solvent phase containing aromatic hydrocarbons and a raffinate phase containing nonaromatic hydrocarbons; (b) cooling said solvent and raffinate phases; (c) introducing said cooled solvent phase to a separation zone and introducing therewith an effective amount of an anti-solvent for said aromatic hydrocarbons in said mixed extraction solvent to provide an extract phase containing aromatic hydrocarbons and a solvent phase containing mixed extraction solvent and anti-solvent; (d) introducing said cooled raffinate phase to a separation zone and introducing therewith an effective amount of an anti-solvent for such aromatic selective solvent in said raffinate phase to provide a raffinate phase containing non-aromatic hydrocarbons and a solvent/anti-solvent phase; (e) adjusting the anti-solvent in said solvent phase and recycling said solvent phase to the extraction zone of step (a); and (f) recovering the extract phase of step (c) and the raffinate phase of step (d).
