Abstract

In the solvent extraction of hydrocarbon oil fractions into relatively more paraffinic and more aromatic fractions the extract phase from one feed stock is employed as solvent for the extraction of a second fraction of overlapping or closely adjacent boiling range to the first. The second fraction is preferably the higher boiling. Conventional solvents and apparatus may be used to extract gasolene, kerosene, Diesel fuel, lubricating oils, aromatic cycle stock obtained in catalytic cracking, and fractions which have been subjected to hydrogenation, hydroforming, isomerization and the like. Light or burning fractions of increasing boiling point may be extracted using SO2 when the sulphur content of the aromatic extract increases from stage to stage while that of the raffinate decreases. Make up solvent such as SO2 or a modifying solvent may be added in the later stages. Thus, a gasoline extract is used for kerosene extraction, the kerosene extract + SO2 used for gas oil extraction, and this extract + benzol used to extract lubricating oil. Solvents recovered from the several extracts and raffinates are treated in a common recovery system. Specification 607,945 is referred to.
