Development of an early gas leak detection system is essential for safety of energy storage tank fields or chemical plants. Contact-type conventional gas sensors are not suitable for remote surveillance of gas leakage in wide area Infrared camera has been utilized for gas leak detection, however it is limited only for detecting particular gas. In this study a new gas leak identification system, which enables us to detect gas leakage and to identify gas type and density, is developed based on infrared spectmm imaging system utilizing low cost and compact microbolometer infrared camera. Feasibility of the proposed system was demonstrated by experimental results on identification of hydrofluorocarbon gas.
