高含硫化氢气田仪表选型设计

Instrument Selection for High Hydrogen Sulfide Gas Field

天然气介质中硫化氢的含量比较高,由于硫化氢的剧毒性和腐蚀性,以及天然气中硫磺颗粒的沉积等工况,仪表的接液材质、选型设计与普通的天然气相比,存在很多不同之处。介绍了压力仪表、温度仪表、液位仪表、流量仪表的选型设计与安装;结合气田在生产运行中仪表维护的经验,探讨了高含硫化氢天然气仪表选型设计的注意事项和建议。

Due to hypertoxicity, corrosion and sulfur particle deposition in natural gas for highhydrogen sulfide content, the wet parts materials and type selection of instrument are quite different comparing to that for normal natural gas. Instrument selection and installation of pressure, temperature, level and flow are introduced. Combining with instrument maintenance experience during production operation for gas field, some design attentions and suggestions of instrument selection for high hydrogen sulfide content natural gas are discussed.
