Abstract

Optical infrared gas analyzers are developed for mixtures of vapors of liquefied natural gas and air. It is found that a network of them allows temperatures of −100 to +60°C to be measured along with volume concentrations of hydrocarbons С = 0.5–100 vol % with temporal responses of less than 1–2 s when analyzing methane–air emissions and clouds in the atmosphere with volumes of up to 10⁷ m³ and data transmitted to a remote server at rates of up to 10 km every 1 ms. It is shown that with large-scale pulsed emissions of liquefied natural gas into the atmosphere or spills of it onto dry ground or water, conditions are created for the long-term formation of flammable and explosive mixtures of air and hydrocarbons at concentrations C = 5–15 vol %.

红外气体分析仪，用于监测可燃气体和爆炸性天然气向大气的排放

摘要

开发了光学红外气体分析仪，用于液化天然气和空气的蒸汽混合物。发现它们的网络可以测量−100至+ 60°C的温度以及烃的体积浓度С = 0.5–100 vol％，分析甲烷-空气排放时的时间响应小于1-2s大气中的云量高达10 ⁷ m ³，数据以每1 ms高达10 km的速率传输到远程服务器。结果表明，随着液化天然气向大气中的大规模脉冲排放或泄漏到干燥的地面或水上，为长期形成浓度为C的空气和碳氢化合物的易燃易爆混合物创造了条件。 = 5–15体积％。
