| description | Lube oil feedstock is produced from atmospheric residue by: (1) vacuum distillation to give vacuum gas oil (VGO); (2) hydrotreating VGO to purify it; (3) hydrocracking purified VGO to produce light hydrocarbons; (4) fractionation to separate light hydrocarbons from unconverted oil (UCO); (5) vacuum distillation of UCO to produce feedstock; and (6) recycling UCO to hydrocracker. Also claimed is a related process in which only part of UCO is vacuum distilled and remainder is recycled to the hydrocracker.
A method for producing feedstocks of high quality lube base oil utilising the unconverted oil of a fuel hydrocracker, comprising the steps of: distilling an atmospheric residue under vacuum in a first vacuum distillation unit to provide a vacuum gas oil; hydrotreating the vacuum gas oil in a first reaction unit to remove impurities therefrom and provide a treated vacuum gas oil; hydrocracking the treated vacuum gas oil in a second reaction unit to yield light hydrocarbons; subjecting the light hydrocarbons to a series of fractional distillations to separate light oil products and an unconverted oil; feeding all of said unconverted oil to a second vacuum distillation unit to produce feedstocks of high quality lube base oil having desired viscosities and an unconverted oil remaining portion; and recycling the unconverted oil remaining portion from the second vacuum distillation unit to the second reaction unit.
Spôsob zahŕňa destiláciu atmosférického rezídua vo vákuu v prvej vákuovej destilačnej jednotke (V1) do vzniku vákuového plynového oleja, hydrospracovanie vákuového plynového oleja v prvej reakčnej jednotke (R1) na odstránenie nečistôt, hydrokrakovanie spracovaného vákuového plynového oleja v druhej reakčnej jednotke (R2) na získanie ľahkých uhľovodíkov, oddelenie ľahkých olejových produktov a nekonvertovaného oleja sériou frakčných destilácií (Fs), napustenie všetkého nekonvertovaného oleja do druhej vákuovej destilačnej jednotky (V2), recyklovanie zvyšnej časti nekonvertovaného oleja z druhej vákuovej destilačnej jednotky (V2) do druhej reakčnej jednotky (R2), úplné alebo čiastočné napustenie nekonvertovaného oleja do druhej vákuovej destilačnej jednotky (V2), pričom recyklovanie zvyšku nekonvertovaného oleja z frakčnej destilácie (Fs) do druhej reakčnej jednotky (R2) je v prípade čiastočného napustenia a recyklovanie zvyšnej časti nekonvertovaného oleja z druhej vákuovej destilačnej jednotky (V2) do druhej reakčnej jednotky (R2).ŕ |
