影响尿素装置合成塔安全稳定运行的主要原因,是化学爆炸和设备腐蚀问题。通过工艺分析认为,合成塔化学爆炸的可能性较小,而设备腐蚀问题应该高度重视。回顾了几年来尿素装置运行情况,分析了加快高压设备腐蚀的原因,采取了措施,合成塔腐蚀加快趋势得到控制。 The main reason that affects the safe and stable operation of the urea plant is the problem of chemical explosion and equipment corrosion. Through process analysis, the possibility of chemical explosion of the synthesis tower is relatively small, and the problem of equipment corrosion should be highly valued. Reviewing the operation of urea plant over the past few years, the reasons for accelerating the corrosion of high-pressure equipment are analyzed, and the measures taken to speed up the corrosion of the synthesis tower are under control.
