摘要
高含硫气田集输系统中的硫组分会因压力、温度和组分等的变化而析出,经成核、聚集过程后逐渐生长为硫颗粒并沉积到管道内壁.硫沉积可导致管道堵塞、设备污染、腐蚀加速、集输系统效率降低等问题,严重威胁集输系统安全.分析了高含硫气田集输系统的硫沉积机理,包括析硫与成核机理、硫沉积来源及影响硫沉积的因素.适用于高含硫气田集输系统硫沉积的非介入式检测技术很少,重点介绍了基于超声波原理的在线检测技术及其在高含硫气田中的应用现状,同时指出了其他检测技术应用于硫沉积检测时存在的不足.
Abstract
The sulfur in the gathering and transportation system of high-sulfur gas field separate out due to the changes of pressure,temperature and composition.The sulfur grows into sulfur particles gradually after the process of nucleation and aggregation and deposits on the inner wall of the pipeline.Sulfur deposition can lead to pipeline blockage,equipment pollution,accelerated corrosion and reduced efficiency of gathering and transportation system,seriously threatening the safety of gathering and transportation system.The mechanism of sulfur deposition in high sulfur gas gathering and transportation system was analyzed,including the mechanism of sulfur evolution and nucleation,the source of sulfur deposition and the factors affecting sulfur deposition.There are few non-interventional detection technologies for sulfur deposition in the gathering and transportation system of high-sulfur gas field.The on-line detection technology based on ultrasonic wave principle and its application status in high-sulfur gas field were emphatically analyzed.At the same time,the shortcomings of other detection technologies in sulfur deposition detection were pointed out.
