Separation and Research of Organosulfur Compounds Content of High-Sulfur Crude Oil

Abstract

A b s t r a c tResearch on extraction of concentrates of organosulfur compounds from sour crude oil using various solvents has been conducted. The composition of organosulfur compounds has been investigated which showed that benzo -and dibenzothiophenes are predominant components of the selected concentrates relating to hard to recover ones from oil and oil products by conventional methods. The hydrogenation was carried out on the example of individual benzothiophene by means of electrophilic hydrogenation systems. The possibility to obtain concentrates of organosulfur compounds with high sulphide content from highly sulphurous oil has been shown.
