天然气净化装置腐蚀行为与防护

Corrosion Behavior and Protection of Natural Gas Purification Unit

由于天然气中含硫物质的影响,天然气净化装置内壁在运行中极易被腐蚀。内腐蚀将导致装置壁厚变薄,严重时甚至会出现壁面穿孔、破裂等问题,造成天然气泄漏事故,严重影响净化装置的安全、稳定运行,对环境也造成一定污染。

Due to the effect of sulfur-containing substances in natural gas, the inner wall of the natural gas purification device can be easily corroded during operation.Internal corrosion will lead to the thinning of the device wall thickness, wall piercing and even rupture may occur even in severe cases, resulting in natural gas leakage accidents, seriously affecting the safety and stability of the purification device and causing some pollution to the environment.
