The atmospheric corrosion due to pure amines emitted from carbon capture plants was investigated. Amine exposure was found to initially inhibit the corrosion of steel, by its film formation and alkalinity, but reduce corrosion product layers and lead to freezing point depression, which could in turn increase the corrosion. Very high amine doses were observed to dissolve the metal without the establishing of a corrosion layer. These effects seem much more pronounced on copper than on steel. Climate and air quality variations affect the steel corrosion much more than the expected maximum amine deposition from carbon capture plant emissions.

碳捕集装置排放的胺引起的大气腐蚀

研究了由于碳捕集装置排放的纯胺引起的大气腐蚀。发现胺暴露最初会通过其成膜和碱度来抑制钢的腐蚀，但会减少腐蚀产物层并导致凝固点降低，这反过来又会增加腐蚀。观察到非常高的胺剂量可溶解金属，而不会形成腐蚀层。这些影响在铜上似乎比在钢上更为明显。气候和空气质量变化对钢腐蚀的影响远大于碳捕集装置排放的预期最大胺沉积量。
