甲烷对碳钢腐蚀的影响

In world regions with extended winter seasons, significant amounts of methanol are injected into wells and pipelines in order to inhibit the formation of natural gas hydrates. However, this application creates an avenue for the intrusion of dissolved oxygen into a pipeline system, since oxygen is more soluble in methanol than in aqueous fluids. In both sweet and sour systems, the presence of oxygen has a negative impact on the corrosion rate of carbon steel. 旋转圆柱电极（RCE)
