连续重整催化剂粉尘的危害与措施

分析扬子石化连续重整装置催化剂粉尘的主要危害。提出减少催化剂粉尘的措施:降低烧焦床层温度来减少催化剂的热崩碎;从控制催化剂提升速率、提高提升管安装质量以及选用机械强度高的催化剂等方面来减少催化剂输送过程中的磨损。通过优化除尘操作、定期清理内网等措施来去除系统中的粉尘。

HAZARDS OF CONTINUOUS REFORMING CATALYST DUST AND ITS COUNTERMEASURES

This paper analyzed the hazards of catalyst dust in continuous reforming unit of Yangzi Petrochemical Co.,Ltd.,SINOPEC.Approaches to decrease catalyst dust were proposed as follows: decrease the regeneration bed temperature to reduce heat collapse of catalyst;control the lift velocity of catalyst,increase the erection quality of lift pipe and adopt catalyst with higher mechanical intensity to reduce the catalyst abrasion in transfer process;The dust was removed by optimizing dust removal process and cleanin...
