Technical analysis and optimization of processing plan for blending imported crude oil
Based on the characteristics of the existing Yulin crude oil,imported crude oil,and mixed crude oil in Yanchang Petroleum Yulin Refinery,this paper analyzes and summarizes the operational problems that occur in the atmospheric and catalytic devices during the blending of imported crude oil,proposes adaptive solutions,and forms a processing plan for imported crude oil with high atmospheric pressure and low vacuum.The results show that the imported crude oil is processed into wax oil under vacuum,and after catalytic cracking or hydrogenation treatment,the produced heavy oil meets the raw material require-ments of the coal oil co-refining unit.The unit has the ability to process high sulfur and sour crude oil,achieves efficient coupling processing between imported crude oil and Yanchang Petroleum's self-produced crude oil,and further increases the blending amount of imported crude oil to effectively improvs the economic benefits of the refinery.
