0.6 Mt/a连续重整装置长周期运行分析

Study on long-term operation of a 14000 b/d CCR unit

介绍了中国石化上海高桥分公司0.6 Mt/a连续重整装置在第三周期运行过程中为确保装置长周期运行所做的操作优化和技术攻关情况。连续重整装置在第三周期安全平稳运行1 100 d,装置负荷率为95.53%,液体产品收率达到90.04%,其中催化剂连续使用2 526 d,循环再生480圈,创造了国内同类装置运行周期最长记录。

In SINOPEC Shanghai Gaoqiao Petrochemical Co. , Ltd. , the operation optimization and technical renovation were successfully performed in the 3rd operation cycle of a 14 000 b/d CCR unit to ensure the long-term reliable operation of the unit. As the result, the unit was operating smoothly for 1 100 days in the 3rd operating cycle at an operating load of 95.53%, the liquid product yield reached 90.04%, and the catalyst was operating continuously for 2 526 days and regenerated for 480 cycles, recording the longest operating cycle in the similar units in China.
