Abstract

Hydrocarbon oils containing aromatics soluble in a liquid selective solvent and having a boilingpoint in the range of the solvent boiling-point and below, are refined by contacting with the solvent and separately distilling the extract and raffinate phases, to distil off from the oil the solvent containing co-boiling aromatics, and contacting the condensed solvent phase with a relatively high molecular weight high-boiling paraffinic oil having a B.P. not less than 580 DEG F. to dissolve the aromatics from the solvent phase, and recycling the solvent to the first extraction zone. Solvents referred to are furfural, with or without water, benzaldehyde, tetrohydrofurfuryl alcohol, ketones, and phenolwater solutions.
