降低催化装置结焦实现长周期运行

Reducing coke formation and realizing long period operation for catalytic cracking unit

大庆石化分公司催化装置近年来原料重质化,结焦严重,经常造成非计划停工。通过总结装置历史运行经验、分析结焦机理、采用抑制结焦新技术和加强生产管理,实现了长周期运行800d以上。

With the heavy trends of feed stocks of Daqing Petrochemical Company's catalytic cracking unit, the severe coking often caused unexpected shutdown. After analysis with the operation history and coking principles, the new technology to restrain coking and extensive production management were put on use. Long term operation of more than 800 days was achieved.
