Abstract

Due to rapid rise of consuming rate for natural gas, installation and operation of high pressure natural gas pipeline is inevitable for high rate of gas transportation. Accordingly incidents on the underground high pressure natural gas pipeline come from various reasons will lead to massive release of natural gas and gas dispersion in the air. Further, fire and explosion from ignition of released gas may cause large damage. This study is for release rate, dispersion and flash fire of natural gas to establish a safety management system, setting emergency plan and safety distance.

천연가스의 사용량이 날로 증가됨에 따라 고용량의 가스를 운송하기 위해 고압배관의 설치 운영이 불가피하고 이에 따라 고압의 매몰 천연가스배관에서 다양한 원인에 의한 결함 발생 시 대규모 누출로 이어지면 높은 압력의 가스 방출에 따른 대기 중 확산 그리고 점화원에 의한 화재 폭발로 인하여 큰 피해가 발생할 수 있다. 이 연구에서는 고압의 매몰 천연가스배관에서 결함 발생 시 매몰된 배관에서의 가스 누출 거동 분석과 가스 확산 및 지연점화에 따른 플래시 화재의 피해 거리를 예측하여, 사고 영향을 감소할 수 있도록 대피거리의 산정 등에 의한 비상조치계획을 세워 안전관리 활동에 도움이 되고자 한다.
