Corrosion is one of the critical problems for process operations and plant life. Amine-based post-combustion CO₂ capture systems are known to be corrosive. This is because of the absorption of CO₂ by aqueous amine solution, which makes the system acidic and generates oxidizing agents through ionization leading to corrosion. Corrosion increases with CO₂ loading, process temperature, presence of oxygen (O₂), occurrence of sulfur compounds, low pH, velocity of solution and formation of some degradation products. Conducting experimental investigations to determine the rate of corrosion at various parts of process plant under a wide range of operating parameters is difficult and costly. Mathematical models and simulations play an important role in estimating the rate of corrosion under wide range of operating parameters for such systems. This study highlights the process of corrosion for amine-based CO₂ capture systems and development of corrosion models with critical analyses on their applications. Study also highlights the outlook of models and simulations.

腐蚀是过程操作和工厂寿命的关键问题之一。已知基于胺的燃烧后CO ₂捕集系统具有腐蚀性。这是因为胺水溶液吸收了CO ₂，使系统呈酸性，并通过电离产生氧化剂而导致腐蚀。腐蚀随着CO ₂负载，工艺温度，氧气（O ₂），硫化合物的出现，低pH值，溶液的速度以及某些降解产物的形成。进行实验研究以确定工艺设备在各种操作参数下各部分的腐蚀速率既困难又昂贵。数学模型和仿真在估算此类系统在广泛运行参数下的腐蚀速率时起着重要作用。这项研究着重介绍了胺基CO ₂捕集系统的腐蚀过程以及腐蚀模型的开发，并对它们的应用进行了严格的分析。研究还强调了模型和仿真的前景。
