含硫化氢油田密封型式的经济性选型

Economic Selection of Sealing Type in Oil Field Containing H2S Sulfide

硫化氢为剧毒气体,国内外文献及标准中表示,硫化氢的阈限值为10ppm,鉴于海洋平台的地理位置的特殊性,机械设备的密封型式的选型对海洋平台操作人员的安全性及工程造价的影响很大,具体项目要根据介质中硫化氢含量、机械设备所处位置的硫化氢气体扩散条件、硫化氢探头及密封型式等进行综合选型,实现技术经济最优。

H2S sulfide is a highly toxic gas.According to the domestic and foreign literature and standards,the threshold limit value of H2S sulfide is 10ppm.In view of the particularity of the offshore platform’s geographical location,the selection of sealing type of mechanical equipment has a great impact on the safety of offshore platform operators and the engineering cost.The specific project should be based on the H2S sulfide content in the medium and the H2S sulfide gas diffusion at the location of the mechanical equipment conditions,H2S sulfide probe and sealing type are selected comprehensively to achieve the technical and economic optimization.
