摘要
介绍了1.8×10^(6 )t/a催化汽油加氢脱硫装置使用Axens公司Prime-G^+工艺进行国V改造后的工艺流程和改造内容,分析了装置改造后开工运行初期满负荷工况和初步优化情况。对开工过程中存在的问题进行分析并提出解决措施。结果表明,Prime-G^+工艺成熟可靠,轻、重及混合精制汽油的各项指标均达到国V汽油指标要求,通过减缓一段、二段加氢脱硫单元的脱硫率等初步优化措施,可降低辛烷值损失,降低辛烷值损失的措施可进一步优化。
This paper introduced the process flow and transformation items of 1.8 Mt/a FCC gasoline hydrodesulfurization unit which used Axens company Prime-G^+technology to transform according to the national standard of grade V gasoline.Initial operation under full capacity and preliminary optimization condition were analyzed.The problems existing in the start-up process were analyzed and solutions were put forward.The results showed that the Prime-G^+process was mature and reliable,and the indexes of light,heavy and blended refined gasoline were up to the requirements of the national standard of grade V gasoline.The octane number loss could be reduced by reducing the desulfurization rate of first stage and second stage HDS,and the measures could be further optimized.
