摘要
在石化生产过程中,危害气体泄漏时有发生,为了快速准确地确定泄漏气体种类,以便及时给事故应急提供指导,提出了基于傅里叶光学红外成像的分析方法,通过远距离遥测识别泄漏气体种类.实验研究了光谱分辨率、气体排放流量对遥测识别的影响,并且在某公司乙烯装置开展了现场泄漏检测与识别应用.识别实验和现场应用结果表明,傅里叶光学红外成像分析方法可以快速定位泄漏气体位置,并且识别气体种类,正确检测并识别目标气体后,进一步减小光谱分辨率和泄漏目标气体流量对气体识别的影响较小,该方法有利于石化生产安全隐患排查与事故应急处置.
Abstract
The leakage of harmful gas occasionally happens in the production process of petroleum and chemical industry.In order to accurately determine the leakage gas types and provide emergency guidance on time,a new optical infrared imaging analysis method based on the Fourier optics is proposed for the identification of leakage gas types.The experiments also study the influence of spectral resolution,the flow of gas emission on telemetry recognition identification,and use the method to detect and identify leakage gas in an ethylene unit.The experiment and field application results show that Fourier optical infrared imaging spectrum analysis can locate the gas position quickly,and identify leakage gas type.After detecting and identifying target gas correctly,reducing the spectral resolution and gas flow has no influence on gas identification.This method is beneficial to finding safety troubles and dealing with emergency accidents.
