The effectiveness of amine and imidazoline-based corrosion inhibitors on carbon steel was compared in CO₂ saturated artificial geothermal water. Weight loss tests were carried out under the influence of the stirring speed in accordance with the conditions that exist on the production side (160 °C) and the injection side (80 °C) in geothermal power plants in the Upper Rhine Graben (URG). Corresponding to a possible two-phase flow, the corrosion behavior and inhibitor performance in the liquid and the gas phase was investigated. In addition, depending on the inhibitor concentration and various hydrodynamic conditions, electrochemical tests such as potentiodynamic polarization and electrochemical impedance spectroscopy (80 °C) were carried out.

比较了胺和咪唑啉类缓蚀剂对碳钢在CO ₂饱和人工地热水中的有效性。根据上游莱茵格拉本（URG）地热发电厂生产侧（160°C）和注入侧（80°C）的条件，在搅拌速度的影响下进行了失重测试。 。对应于可能的两相流，研究了液相和气相中的腐蚀行为和抑制剂性能。另外，根据抑制剂的浓度和各种流体力学条件，进行了电势极化和电化学阻抗谱（80℃）等电化学测试。
