一、前言天然气开发的早期经验已表明,金属材料暴露在含硫(硫化氢)气体介质中会很快腐蚀损坏,以致造成工艺设备失效,而且这种损坏的发生往往是非常突然,造成的事故有时是难以收拾。因此,对含硫油气田开发的每一项设计,材料选用,质量控制和施工。人们关心的是它们是否适合含硫介质,在所有项目都能作肯定答复之后再考虑经济问题。我网开发天然气事业还很年青。自动化水平还很低。缺乏耐硫仪表是不能实现自动化生产的根本原因。根据某气田一个集气站统计,采用的常用非耐硫仪表,共8大类,
I. INTRODUCTION Early experience with natural gas development has shown that exposure of metal materials to sulfur (hydrogen sulfide) -based gas media quickly corrodes and causes process equipment to fail, and the occurrence of such damage is often very sudden and causes an accident Sometimes it is difficult to clean up. Therefore, every design, material selection, quality control and construction developed for sulfur-bearing oil and gas fields. People are concerned whether they are suitable for sulfur-containing media and then consider economic issues after all projects have been answered in the affirmative. My network is still young to develop natural gas. The level of automation is still low. The lack of sulfur-tolerant instrumentation is the fundamental reason why automated production can not be achieved. According to a gathering gas station statistics, commonly used non-sulfur-tolerant instruments, a total of 8 categories,
