在工程固碳储存库中，当排放气体在深层地质层中压缩时，注入管钢的二氧化碳腐蚀是一个相关的安全问题。在等效腐蚀环境（T = 60°C, p = 1-60 bar，含水层水，co2流速为3 L/h，暴露时间为700-8000 h）的实验室实验中，证明了适用于德国Ketzin地质岸上ccs（碳捕集与封存）站点的钢的可靠性。采用套管用热处理钢42CrMo4（1.7225）和马氏体不锈钢注射管钢X46Cr13（1.4034）的腐蚀动力学和显微组织进行了研究。
In engineering storage sites for Carbon Sequestration the CO2-induced corrosion of injection pipe steels is a relevant safety issue when emission gasses are compressed in deep geological layers. The reliability of the steels suitable for the geological onshore CCS-site (Carbon Capture and Storage) at Ketzin, Germany, is demonstrated in laboratory experiments in equivalent corrosive environment (T = 60 °C, p = 1–60 bar, aquifer water, CO2-flow rate of 3 L/h, 700–8000 h exposure time). Corrosion kinetics and microstructures were characterized using specimens of the heat treated steel 42CrMo4 (1.7225) used for casing, and specimens of the martensitic stainless injection-pipe steel X46Cr13 (1.4034).
