93号汽油调合方案的改进

摘要

Due to lack of alkylation and pyrolysis gasoline blending components, qualified 93# gasoline could not be produced in Huizhou Refinery. In order to solve this problem, the blending scheme should be adjusted. Measures, such as using low sulfur FCC feedstock to reduce the sulfur content of the main FCC gasoline blending component, declining the blending ratio of CCR reformate to limit benzene content, and adding raffinate from aromatics extraction as blending component to minish gasoline vapor pressure were adopted. Results showed that the quality of the gasoline product obtained by the improved blending scheme could well meet the demand of national standard for 93# gasoline product.%中海炼化惠州炼油分公司对93号汽油调合方案进行改进,以解决由于烷基化汽油和裂解汽油缺乏造成的93号汽油无法调合的问题.通过合理调整催化裂化原料降低催化裂化汽油硫含量、限制重整生成油调合比例、增加芳烃抽余油量降低汽油蒸气压等方法对调合方案进行了改进.采用改进的调合方案得到的汽油完全能满足93号汽油的质量标准要求.
