摘要：

红外光谱成像遥测技术是一种新兴的气体泄漏监测技术，因缺乏现场试验支撑，鲜有应用。某炼化企业应用该技术在罐区、装置区以及烟囱等区域开展了现场试验，并对罐顶气样进行了气相色谱法分析，将光谱遥测数据分别与环境气样气相色谱法分析数据和污染源在线监测数据进行了对比。结果表明，红外光谱成像遥测识别的气体组分与气相色谱法分析组分相同，浓度变化趋势与污染源在线监测浓度变化趋势基本一致，有效识别了苯、甲苯以及二氧化硫等十余种组分，构建了气体扩散羽流轨迹，实现了可视化显示，为该技术的推广应用提供了试验支持。

Abstract:

Infrared spectral imaging telemetry is a novel technology for gas leakage monitoring which is rarely applied in practice due to the lack of field test. A refining and chemical enterprise applied this technology to carry out field tests in tank farm, unit area and chimney, and analyzed the gas samples on the tank top by GC(gas chromatography). The spectral telemetry data are compared with the GC data of environmental gas samples and the on-line monitoring data of pollution sources. The results show that the gas components identified by infrared spectral imaging telemetry are the same as those by GC, and the concentration change trend is basically consistent with the on-line monitoring of pollution source. More than ten kinds of gases such as benzene, toluene and sulfur dioxide are effectively identified, the gas diffusion plume trajectory is constructed, and the visual display is realized, which provides experimental support for the popularization and application of this technology.
