This review paper discusses the research work published in the last decade on the use of organic compounds and natural products as corrosion inhibitors for steel in CO and CO /H S coexisting environments. The carbon and mild steel samples tested are mostly immersed in CO -saturated NaCl/brine solutions or simulated oilfield waters. The influence of temperature, immersion time, CO partial pressure, pre-corrosion, flow rate/rotation speed, and the synergistic effect of other compounds on the corrosion inhibition effectiveness of organic compounds and natural products is presented. Primarily, weight loss and electrochemical techniques were used to evaluate the corrosion inhibition effectiveness of these compounds.
这篇综述论文讨论了过去十年间发表的关于在CO和CO/H₂S共存环境中使用有机化合物和天然产物作为钢的缓蚀剂的研究工作。所测试的碳钢和低碳钢样品大多浸泡在CO₂饱和的NaCl/盐水溶液或模拟油田水中。介绍了温度、浸泡时间、CO₂分压、预腐蚀、流速/转速以及其他化合物的协同效应对有机化合物和天然产物缓蚀效果的影响。主要采用失重法和电化学技术来评估这些化合物的缓蚀效果。
