Why Infrared Cameras Can "Capture" Gas Leaks

The Necessity of Using Gas Infrared Cameras

With the continuous development of industrialization, flammable, explosive, and toxic gases as products, raw materials, or by-products of industrial production have become widely present in every corner of social life. Once these gases leak, they not only pollute the environment but also pose threats to people's lives and property.

For example, there are numerous pipelines, valves, and storage equipment in the natural gas industry and chemical plants that may lead to gas leaks due to aging, corrosion, or improper operation. Volatile organic compounds released from biofuels and exhaust emissions can also harm the environment and people. To prevent major accidents, quickly detecting gas leaks, locating the source of leaks, and assessing gas distribution and diffusion trends are urgent problems that need solutions.

Traditional gas leak detection methods such as the bubble method, funnel method, or gas detectors generally have small detection coverage, making the detection process time-consuming and labor-intensive; they require close detection distances, potentially threatening the safety of operators; they detect single types of gases, requiring multiple detectors which are not easy to carry; and sometimes production lines have to be shut down for inspections, wasting man-hours and possibly damaging normal equipment.

Gas Infrared Cameras, with their safe and efficient advantages, have gradually become the preferred tools in the field of gas leak detection.

Advantages of Gas Infrared Cameras

Thermal imaging cameras have significant advantages such as visualization, safety, efficiency, and non-stop equipment running in gas detection. They can quickly detect the presence of gas leaks, locate the source of leaks, and assess gas distribution and diffusion trends effectively, preventing accidents and ensuring the safety of life and property.

• Gas Visualization: Gas Infrared Cameras can visualize invisible toxic and harmful gases through optical gas imaging and professional gas image enhancement algorithms. They do not require auxiliary light sources or reflective backgrounds and can be directly filmed with the sky as the background, helping to quickly locate leak points.

• Safe and Efficient: Gas Infrared Cameras can quickly screen target areas under non-contact, long-distance, and large-scale conditions, reaching areas that personnel cannot touch, locating the leak source, and completing gas leak detection work safely and efficiently.
  

• Non-stop Equipment Running: Traditional detection methods are often difficult to perform under running equipment conditions. However, Gas Infrared Cameras can detect during normal equipment operation without the need for shutdowns or production halts. This feature enables users to detect leaks without affecting production, thereby reducing production losses.

Why Gas Infrared Cameras Can Detect Gas Leaks

When gas leaks, it will absorb infrared radiation at specific wavelengths (characteristic peaks of gas infrared absorption). Due to the difference in infrared radiation characteristics between the leaking gas and the surrounding environment, this difference will form an obvious infrared radiation difference under the detection of an infrared thermal imaging camera. Gas Infrared Cameras utilize this principle to accurately identify leaking gas and its location by capturing and analyzing this infrared radiation difference.
