Abstract

The results of one-step extraction treatment of delayed coker heavy gas oil from the Gazpromneft–Omsk Oil Refinery to remove sulfur- and nitrogen-containing components and polyaromatic and unsaturated hydrocarbons are presented. The extraction was performed with N-methylpyrrolidone at the N-methylpyrrolidone : feed ratios of 0.3 : 1 and 0.5 : 1, with moist (2 wt % water) N-methylpyrrolidone at the extractant : feed ratio of 0.5 : 1, and with the N-methylpyrrolidone–heptane extraction system at the polar component : feed ratio of 0.5 : 1 and nonpolar component : feed ratio of 0.2 : 1. The physicochemical properties of the raffinates and extracts, their composition, and degree of removal of components whose content in diesel and ship fuels is subject to environmental regulations are described.
