为解决油田氧腐蚀问题,以反式对甲氧基肉桂醛、3-氨基苯甲酸为主要原料合成了具有多个吸附位点的席夫碱缓蚀剂TMCAM。首先,通过动态失重法评价了不同浓度的席夫碱缓蚀剂TMCAM在60 ℃含氧油田模拟配水中对Q235钢的缓蚀性能。结果表明,在TMCAM质量浓度为60 mg/L时,Q235钢的腐蚀速率为0.062 4 mm/a,满足现场要求;TMCAM投加质量浓度为100 mg/L时,Q235钢腐蚀速率仅为0.036 8 mm/a,缓蚀率可达到90%。其次,采用扫描电镜、电化学法 ...

臭氧催化氧化技术在炼厂污水处理领域的应用较为广泛,但装置在长周期运行过程中经常出现不同程度的腐蚀问题,尤其是奥氏体不锈钢的设备及管道。为了明确炼厂不锈钢设备及管道在含臭氧污水环境下的腐蚀特性,采用电化学试验和浸泡试验,以316L材质为主要研究对象,系统研究了其在含臭氧模拟污水环境中的腐蚀行为,并推测臭氧与Cl-共同作用下不锈钢的腐蚀机制。结果表明:环境温度升高、pH偏离中性、臭氧浓度升高、Cl-质量浓度升高、SO42-质量浓度降低均会增大316L在污水环境中的点蚀敏感性,使其耐腐蚀性能下降;在焊接接头中,
