Abstract

Due to the development of industry and improvement of living standards, the amount of natural gas used in the world is constantly increasing, and related industrial facilities such as power plants, storage facilities, and supply pipelines are constantly increasing. Natural gas is a convenient and clean fuel that does not pollute the environment, but in the event of an accident due to leakage, it can cause human casualties, large-scale property damage, and negative effects on the global warming effect. In addition to the severe penalties under the Severe Disaster Punishment Act, it is necessary to ensure safety. Therefore, by applying the principle of laser-based absorption spectroscopy, we developed a long-range portable methane leakage gas detection system that can detect the concentration of methane leaking from a distance of up to 30 meters and verified its effectiveness.

산업의 발전과 생활 수준의 향상으로 인하여 전 세계적으로 천연가스의 사용량은 지속해서 증가하고 있으며, 이에 따른 발전소, 저장시설, 공급배관망 확충 등 관련 산업시설도 지속해서 증가하고 있다. 천연가스는 편리하고 환경오염이 없는 청정연료이지만 누출로 인한 사고 발생 시, 인명피해는 물론 대규모 재산상 손해, 지구 온실효과에 부정적인 영향을 초래한다. 중대재해 처벌 등에 관한 법률 등도 무거운 상황에서 더더욱 안전을 기해야 할 상황이다. 이에 레이저 기반 흡수 분광분석법의 원리를 적용하여 최대 거리 30m에서 누출되는 메탄 농도를 검출할 수 있는 원거리 휴대용 메탄 누출 가스 검지 시스템을 개발하여 그 효과성을 검증하였다.
