Abstract

Carbon capture, utilization, and storage (CCUS) technology is widely recognized as a key solution for mitigating global climate change. Consequently, it has received significant attention from countries worldwide. However, carbon dioxide corrosion poses a significant challenge to CCUS and represents a bottleneck to the large-scale development and application of this technology. To mitigate this issue, this review starts with a discussion of corrosion problems in CCUS. Later, the fundamentals of the carbon dioxide corrosion mechanism are introduced. Then, the influences of various factors that affect the corrosion are highlighted, such as water content, pH, flow rate, etc. Afterward, we summarize the commonly used methods for corrosion protection, with a particular focus on inhibitor, given their eco-friendly and effective nature. Lastly, challenges and prospects are discussed to motivate future studies on developing novel, high-performance green inhibitor and studying the corresponding protection mechanisms, hoping to make some contributions to carbon emission reduction.

摘要

碳捕获、利用与封存（CCUS）技术被广泛认为是缓解全球气候变化的关键解决方案。因此，它受到了世界各国的高度关注。然而，二氧化碳腐蚀对CCUS构成了重大挑战，是该技术大规模开发和应用的瓶颈。为缓解这一问题，本综述首先讨论了CCUS中的腐蚀问题。随后，介绍了二氧化碳腐蚀机理的基本原理。接着，强调了影响腐蚀的各种因素的影响，如水含量、pH值、流速等。之后，我们总结了常用的腐蚀防护方法，特别关注缓蚀剂，因为它们具有环保和有效的特性。最后，讨论了挑战和前景，以激励未来对开发新型高性能绿色缓蚀剂及研究相应防护机制的研究，希望为碳减排做出一些贡献。
