PINE: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.
This paper is a review of multiple studies carried out in our laboratory over the past five years; the effect of anaerobic and aerobic methanol on the corrosion rate of carbon steel in both sweet and sour environments will be presented.
