大化肥装置停运期间设备触媒保护及装置充氮防腐解决措施

Catalyst protection and nitrogen filling corrosion prevention measures for chemical fertilizer plant equipment during shutdown of chemical fertilizer plant

本文主要针对大型化肥装置区域无设备触媒保护及装置防腐用氮气的问题,在无法使用炼油厂中压氮气等来源的条件下,通过技术改造,提出了从炼油厂反送低压氮气的解决措施。

This paper focuses on the problem of nitrogen in the field of no-equipment catalyst protection and equipment anti-corrosion in chemical fertilizer plant during the period of chemical fertilizer shut-down.Under the condition of not using the source of the oil refinery medium pressure nitrogen and other sources,the solution to the low pressure nitrogen from refinery was put forward.
