Beschreibung
Zusammenfassung:	petroleum processing. SUBSTANCE: process including vacuum rectification to yield lube oils, purification of the latter with selective solvent, low-temperature deparaffination, vacuum distillation, and catalytic after-purification is distinguished by that said low- temperature deparaffination involves lube oil fraction with boiling range 280 to 460 C to yield dewaxed oil with freezing temperature from 50 to 60 C, which is distilled to separate light fraction with dry point 320-340 C and freezing temperature from 55 to 60 C and residual fraction boiling between 320 and 340-460 C. EFFECT: simplified process. 1 tbl, 5 ex
