- 摘要:
- 天然气处理设备,如矿场集输中的过滤分离器、气液分离器、脱水吸收塔、固体脱硫塔,天然气净化厂中的原料气过滤器、原料气分离器、脱硫吸收塔、再生塔、酸气分离器、活性炭过滤器等,所接触的介质基本上都含有水和硫化氢,这种介质环境对设备会产生电化学腐蚀、硫化物应力开裂(SSC)和氢诱发裂纹(HIC)。针对硫化氢对设备的不同腐蚀情况,在设备设计时应采取相应的对策和措施来防止腐蚀,以确保设备的安全运行和使用寿命。
Media,which natural gas processing equipment(such as filter separator,gas/liquid separator,dehydration absorption tower and solid desulfurization tower at gas gathering and transportation station,feed gas filter,feed gas separator,desulfurization absorption tower,regeneration tower,sour gas separator,active carbon filter,etc.in natural gas purification plant) is exposed to,contain water and hydrogen sulfide basically.Such media environment will produce electrochemical corrosion,sulfide stress cracking(SSC) and hydrogen-induced cracking(HIC) in the equipment.Corresponding countermeasures and measures are proposed in equipment design according to different hydrogen sulfide corrosion conditions to prevent scuh corrosion and ensure safe operation of equipment during its service life.
