摘要: Corrosion inhibitors and processes, uses, methods, compositions, devices, and apparatus involving corrosion inhibitors are disclosed. In certain embodiments the use of specific corrosion inhibitors, specific concentrations of inhibitors, blends of inhibitors, processes utilizing such inhibitors, and compositions comprising such inhibitors, for example in acid gas separation systems such as aqueous amine- or ammonia-based CO2 separation systems (e.g., the post combustion capture of CO2 from flue gases using amines). According to some embodiments, corrosion inhibitors are used in a process for separating at least a portion of an acid gas from a gaseous mixture wherein the inhibitor is at least one selected from dodecylamine, sodium molybdate, morpholine, or a combination thereof.
