摘要
二氧化碳是一种弱酸性气体，它在石油及气体工业中是一种腐蚀剂，它在天然气中的含量少则痕迹，至５０％以上。在未经处理的输送气体的金属管线内，ＣＯ２具有不可忽视的腐蚀作用。将对干ＣＯ２以及它和水气并存时对管线腐蚀的机理、影响腐蚀的因素以及如何防腐等问题进行理论分析和讨论。
Carbon dioxide is a species of weak acidic gas, it is a erodent in oil and gas industries, its content in natural gas may vary from trace to more than 50%.The erosion effect of CO2, is not neglectable in the unhandied metal pipes of transporting gas. The erosion mechanism of CO2 and its influencingfactors are discussed and analysed in theoretically whether CO2 contains or does not moisture. In addition, other releviant questions, such as the anticorrosive xneasures etc., are studied in this paper.
