Abstract

A process of producing a plurality of different lubricating oils from a reduced crude oil, and of recovering a by-product material with a higher boiling range, which comprises treating a reduced crude oil through a low loss carp vacuum tower maintained at a pressure less than 50 mm Hg, arranged to separate a plurality of different lubricant base fractions of different relatively narrow boiling ranges, from a fraction that is above the sudden vaporization range, in the form of an initial portion above 537ºC and a residue fraction under vacuum, treat each of said relatively narrow boiling range fractions by a plurality of solvent extraction operations to extract enough unwanted aromatics and paradyne to produce mixture fractions of lubricants of normal and premium quality, treat this fraction ion above the flash range mixed with a selected portion of such residual fractions by propane deasphalting, to produce a refined material phase and an asphalt phase, and treating the refined material phase by extraction with solvents to produce an improved high-viscosity lubricant (bright stok).
