摘要
对CMS(甲烷氯化物)生产工序中20#钢的现场腐蚀情况进行了统计,探讨了HCl-H2O-CMS体系对20#钢的腐蚀规律及其机理。调查分析认为,HCl-H2O-CMS体系对20#钢腐蚀的主要影响因素是体系中HCl和H2O的含量,同时对采集数据拟合了腐蚀速率方程。最后针对该体系腐蚀的现象和特征,对操作工艺、部件材料及结构等进行了改进,实际应用后取得了良好的效果。
Effects of HCl-H2O-CMS system on corrosion of 20^# steel was studied by using corrosion field data in the process of methane chlorination production. The main influecing factors of 20^# steel corrosion in HCl-H2 O-CMS system were the content of hydrochloric acid and water. Corrosion rate equation was also obtained by fitting corrosion field data. According to corrosion feature of 20^# steel in this system, the process, structure and materials were improved.
