| Abstract: |
| Carbon capture, utilization and storage is regarded as one of the important measures to achieve long-term absolute carbon emission reduction, which is crucial for reducing CO2 emission in global. CCUS is also the only way and the most important measure to achieve long-term green and low-carbon development in our country. However, the high-speed growth of CCUS technology would definitely cause corrosion and protection problems of equipment. In this article, the CO2 corrosion of capture equipment, transport pipeline and oil well involved in oil and gas extraction and CCUS is focused on. The corrosion mechanism, which includes the process of CO2 corrosion and different factors (like water content, ions, temperature, pressure, flow rate and oil phase) that affect CO2 corrosion, has been expounded and replenished in detail, especially under high temperature and high pressure. Three methods against CO2 corrosion are introduced. Considering the high cost of alloy protection and the pollution of corrosion inhibitors created to environment, the lower-cost and non-pollution coating protection has a better prospect. The research focus and prospects of CO2 protection coating are analyzed in the end. This article is significant for CO2 corrosion process of the equipment and the selection, design and application of protection coating in CCUS industrial application. |
