石油石化企业泄漏检测技术现状及前景

石油石化站场设备繁多,挥发性介质泄漏易造成安全事故。目前站场点式、线式等固定式检测设备存在泄漏检测反应滞后、泄漏点定位困难等缺点,便携式检测设备人工巡检工作量大。文章对可调谐二极管激光吸收光谱技术、红外热成像技术、红外多光谱技术和红外高光谱技术进行了分析,提出红外成像检测技术在泄漏检测方面优势明显,具有视频成像、反应迅速、定位准确、连续监控等优点,有望在石油石化行业普及。

Current Status and Prospects of Leakage Detection Technology in Petroleum and Petrochemical Enterprises

There are various equipment in petroleum and petrochemical stations,and it is easy to cause safety accidents due to the volatile medium leakage.At present,the fixed detection equipment,including the point type and line type,show some shortcomings at the station,such as delayed response of leakage detection and difficulty in locating leakage point and etc.The manual inspection work of portable detection equipment is heavy.This paper analyzed the active infrared imaging detection technology,infrared thermal imaging technology,infrared multispectral technology and infrared hyperspectral technology.Results showed that the infrared imaging detection technology has obvious advantages in leak detection,with video imaging,rapid response,accurate positioning,and continuous monitoring and so on.It is expected to be popular in the petroleum and petrochemical industry in the detection of media leakage.
