Description

Methane is common in the extraction of oil, coal and natural gas resources and chemical industry production, is the main components of natural gas and it could not effectively to gas leak monitoring and reported to the police, in the process of gas production, LNG transportation and storage variation in leak explosion hazard, so several incidents happened in recent years, Causing casualties and property losses; In the petroleum, coal mining, chemical production, biogas application and other fields, safety accidents caused by gas leakage also occur from time to time, which seriously threatens the safety of human life and property.
In order to avoid and reduce the loss caused by gas leak to the greatest extent, it is increasingly important to develop real-time detection and leakage monitoring technology of methane gas.
GF320 is a OGI thermal imaging camera of displaying and CH4 and VOCs leaks without stopping operations. The portable thermal imager is able to detect leaks from a safe distance, providing operator safety, and it can track gases that are hazardous to the environment for environmental protection benefits. GF320 is suitable for industrial applications such as refineries, gas treatment plants, offshore oil and gas platforms, chemical/chemical industries, biogas plants and power plants.
GF320 also built-in GPS, laser ranging and other functions, very practical.

Principle
Methane is commonly used in the exploitation of petroleum, coal and natural gas resources and in chemical production. It is an important fuel and chemical raw material, as well as a major component of natural gas. In recent years, the proportion of natural gas exploitation and use in China is increasing day by day. At present, liquefaction technology can be used to transport and store liquefied natural gas (LNG) well, which facilitates people's life and promotes economic growth. Due to the inability to effectively monitor and alarm gas leakage, it is easy to produce leakage and explosion potential in the process of gas mining, LNG transportation and storage. Therefore, several accidents have occurred in recent years, causing casualties and property losses. In the fields of petroleum, coal mining, chemical production and biogas application, safety accidents caused by gas leakage also occur from time to time, which seriously threatens the safety of personnel's lives and property.
In order to avoid and reduce the loss caused by gas leakage to the greatest extent, it is increasingly important to develop real-time detection and leakage monitoring technology of methane gas. Infrared imaging method includes infrared spectral imaging method and infrared thermal imaging method. Among them, the reaction speed of infrared spectral imaging is slow, the structure is complex, and the key components have not broken through the technical blockade in China. And infrared thermal imaging method through the infrared optical system, infrared filter and infrared focal plane detector measured gases direct detection of specific absorption peak wavelength of the infrared thermal radiation characteristic signal, through the photoelectric conversion and converts gas leak to the human eye visible image processing image, to be able to dynamically and visually determine leakage position, and can realize gas leakage alarm.

CH4 is the main component of gas and natural gas, and it is easy to cause explosion when it leaks

Monitor renderings
According to the theory of gas molecular spectrum, methane gas has four characteristic absorption peaks in the wavelengths near the positions of 1.6 μm, 2.3 μm, 3.31 μm and 7.67 μm. The absorption peaks at 1.6 μm and 2.3 μm in the near infrared band are weak, the absorption peaks at 3.31 μm in the middle infrared band and 7.67 μm in the far infrared band are strong, which can be used for methane gas detection.
