低硫与含硫原油加工经济效益分析

2004年以来全球石油需求大幅增加，特别是低硫原油需求十分旺盛，造成低硫与含硫原油的价差创下历史新高。文章分析了低硫原油与含硫原油价差扩大的原因，并从炼油毛利和加工成本等方面对两种原油的加工经济效益进行了剖析，提出了大力发展炼油加氢工艺、提高含硫原油加工能力是今后炼油厂发展的必然趋势。

Analysis on Economic Profits of Processing of Sweet Crude and Sour Crude

Since 2004, the global demand of petroleum has increased greatly, especially the demand of sweet crude, which caused the historically high price difference between sweet crude and sour crude. This paper analyzed the reasons for this circumstance, and discussed the processing economic profit of the two kinds of crude oil in aspects of gross profit of petroleum refining and processing cost, and concluded that to vigorously develop petroleum refining hydrogenation process and improve the processing capacity of sour crude is the necessary developing trend of petroleum refining plants in the future.
