目前,我国大多数大中型合成氨厂采用热钾碱(热的碳酸钾)溶液脱除合成气中的CO_2,并用钒酸盐或五氧化二钒作缓蚀剂。本文用旋转电极,从而在流体力学条件稳定的热钾碱溶液中研究碳钢的阳极溶解特性和钒酸盐缓蚀剂的致钝作用。这方面的工作迄今未见有文献报道。结果与讨论一、热钾碱溶液中碳钢阳极溶解的特 At present, most large and medium-sized ammonia plants in our country use hot potash (hot potassium carbonate) solution to remove CO_2 from syngas and use vanadate or vanadium pentoxide as corrosion inhibitors. In this paper, the rotating electrode was used to study the anodic dissolution behavior of carbon steel and blunt effect of vanadate inhibitor in hot potash solution with stable hydrodynamics. So far no literature has been reported on this aspect of work. Results and discussion First, hot potash solution carbon steel anode dissolved special
