Overview of the application of VOCs gas leakage infrared thermal imaging technology in the field of petrochemical industry

With the development and progress of society and the acceleration of industry, transportation and urbanization, volatile organic compounds (Volatile Organic Compounds, VOCs) from extensive sources have increasingly prominent effects on the atmospheric environment, and some of them also have irritant, toxic and carcinogenic effects, posing a serious threat to the ecological environment and human health. As the source of energy in the national economy, the petrochemical industry is an important source of man-made VOCs leakage emissions, and has potential huge safety risks. This article reviews the definition of VOCs, source, hazard and traditional leakage detection method, investigate the progress and application of infrared detection technology at home and abroad, infrared detection technology with its non-contact, long distance, high efficiency, wide range, rapid positioning, dynamic intuitive significant advantages, can play an important role in the petrochemical VOCs detection.
