A low-temperature infrared optical gas analyzer based on immersion diode optocouplers with a speed of less than 0.03 s has been developed to detect pulsed emissions into the atmosphere of explosive mixtures of liquefied natural gas and alkanes with air at a temperature of more than 150 K with the transfer of digitized data to a remote server. The design is described and its characteristics are given in the process of analyzing mixtures of air with pure methane, ethane, propane and LNG of various compositions. It is shown that the speed and operating temperature range of the gas analyzer exceed the parameters of foreign and domestic analogues for monitoring man-made LNG emissions into the atmosphere.
