摘要
从CO2 的腐蚀机理、腐蚀影响因素(如CO2 分压、温度、pH)介绍了CO2 腐蚀研究现状,高温、高压对管道腐蚀速率影响较大,需采取合适措施.重点综述了加入缓蚀剂、耐蚀管材、涂层等防腐方法,结合机理以及防腐措施,提出了未来绿色高效、低成本、低污染的绿色防腐材料的研究趋势.
Abstract
The current status of CO2 corrosion research is introduced in terms of CO2 corrosion mechanism,corrosion influencing factors such as CO2 partial pressure,temperature and pH.High temperature and high pressure both have a great impact on the corrosion rate of pipelines,which needs to take appropriate measures.Anti-corrosion methods are reviewed,such as adding corrosion inhibitors,using corrosion-resistant pipes,using coating,etc.Combining the mechanism as well as anticorrosion measures,the future research trend for efficient,low-cost,low-pollution and green anticorrosion materials is proposed.
