摘要
管道腐蚀对基建的各个方面都有巨大影响,从建筑、桥梁、公路到石油和天然气、化学处理、水和废水系统。对管道CO_(2)腐蚀(甜蚀)以及几种影响因素进行了概述,论述了管道CO_(2)腐蚀机理、化学过程和多场耦合,探讨了影响管道甜蚀的影响因素。针对管道腐蚀造成了环境破坏现象,介绍了一种缓解技术,但关于缓解局部腐蚀的综述还缺乏。结果表明:pH值、氧气浓度、铁含量、CO_(2)分压、温度效应、流体均对管道甜蚀产生较大影响。FBE(熔接环氧树脂)是目前防止局部腐蚀的有效方法。同时,用软件COMSOL耦合输油管道腐蚀进行了设想和展望,以促进管道甜蚀研究工作的发展。
Pipeline corrosion has a huge economic impact on all aspects of the infrastructure, from buildings, bridges, roads to oil and gas, chemical treatment, water and wastewater systems. The CO_(2) corrosion(sweet corrosion) of pipeline and several influencing factors were summarized, the CO_(2) corrosion mechanism, chemical process and multi-field coupling of pipeline were discussed, and the influencing factors of sweet corrosion of pipeline were analyzed. Aiming at the phenomenon of environmental damage caused by pipeline corrosion, a mitigation technology was introduced, but the review on mitigation of local corrosion was still lacking. It was concluded that pH value, oxygen concentration, iron content, CO_(2) partial pressure, temperature effect and fluid all had great influence on sweet corrosion of pipeline. FBE(fused epoxy resin) is an effective method to prevent local corrosion. At the same time, the software,COMSOLwas used to couple the corrosion of oil pipeline, so as to promote the development of pipeline sweet corrosion research.
