  • LPG is a substance that requires a lot of attention because it can cause fatal damage to people and environment when an accident occurs. LPG is frequently accidents in transportation facilities as well as fixed facilities, among which LPG tank lorries are the most frequent accidents. When the LPG tank is evacuated, the LP gas leaks into two phases, leaks mostly to the gas and leaks to some liquid. At this time, the leaked gas will also sink downward because it is heavier than air, and if it continues to leak, it may form an explosion and explode by the ignition source. The purpose of this study is to present the evacuation distance by analyzing the effect distance of the LPG liquefied petroleum gas in the event of explosion. As a result of calculation of the scattering radius of the fragment, the cylinder fragment was scattered up to 561 m. Therefore, it is appropriate to set the distance to be escaped when the LPG tanker leaks to 561m or more.

  • 지난 30년간의 LPG(Liquified Petroleun Gas)자동차의 사용으로 현재 전국에는 600여 곳의 LPG자동차 충전소가 운영되고 있다. LPG자동차의 운행대수에 비하면 충전소의 수가 절대적으로 부족하고, 또한 LPG자동차의 보급확대를 위해서는 충전소 확충이 절대적으로 필수적이다. 그러나 최근의 부천의 가스충전소 폭발사고, 아현동 도시가스 밸브기지 폭발사고와 같은 대형가스 폭발사고의 여파로 충전소 설치 부지확보에 큰 어려움을 격고있다. (중략)

  • Demand of LPG and LNG will increase continuously due to high calories, clearness, and convenience for usage. These gases are used widely for power plants, industrial plants, and domestic fuel. But accidents related with gas are increasing in proportion to increment of gas usage. Especially LPG has high ignitability due to weak dispersion to air and accumulation at low place because LPG is heavier than air. There are many hazards during transportation as well as production, storage, and usage of LPG. Commonly, tank lorry is used for inland transportation of LPG. If tank lorry were to raise leakage incidents and then LPG released during transporting, the accidents cause serious effects on the environment as well as human damage of surrounding area. In this study, therefore, hazards which cause LPG of tank lorry to leak during transportation were identified and risk of LPG transportation was assessed quantitatively. Also, the result of this study might be a useful measure for predicting damage and preparing safe transportation strategies of LPG tank lorry.

  • 도심지내에 위치한 부천 LPG충전소 사고 조사를 통하여 가장 피해효과가 큰 탱크로리 폭발에 따른 결과를 분석하였다. 분석범위는 BLEVE 현상에 의한 방출열과 과압이 충전소 주변에 위치한 구조물이나 인체에 미치는 영향을 대상으로 실제 현장조사를 통하여 수집된 피해결과와 이론적인 모델(PHAST-Process Hazad Analysis Software Tools) 분석 결과를 비교하였다. 부천 LPG 충전소 폭발 사고의 피해효과는 방출열의 경우 두 가지 모두 큰 차이를 보이지 않았으나 과압의 경우, 실제 피해는 이론적 모델 분석결과의 약 15%정도에 해당하는 축소된 거리에서 나타났다. 또한 충전소 인근에 위치한 구조물에 대한 피해효과는 부분적으로 과압에 의한 균열 및 붕괴 현상보다는 열 효과에 의한 콘크리트 강도 저하와 성상변화가 크게 나타났다.

  • In order to investigate the damage mechanism of the coupler transferring LPG, microstructural observation and chemical analysis of the couplers operated for the long time in the LPG stations and virgin 6/4 forged-brass corrosion-tested were conducted. Their microstructure was consisted of two phases that bright $\beta$ precipitates were irregularly dispersed in $\alpha$ matrix. The chemical compositions of oxide layer on the surface of the used coupler were composed of S, C, O, Al, Si, etc. as well as Cu and Zn. In environmental corrosion tests of both $10\%$ HCl and Mattsson solutions, no apparent deviations in mechanical impact strength of forged-brass was observed. While, in U-bend stress corrosion cracking specimen, some microcracks were observed.

  • The advancement of industry have increased domestic energy demands and energy facilities such as storage facility, compressed gas pipe, station, and tank lorry. Also, concern about environment have diversified energy source to clean energy such as LNG. In these major energy facilities, major accident can happen to result in fire, explosion, toxic release and etc. In addition, it may cause chain accidents to the adjacent energy facilities. In this research, safety assessment was performed through the consequence analysis of LPG liquefied petroleum gas) station, gasoline station and LNG(liquiefied natural gas) station. The obtained result will be helpful to make a safety guideline of the LPG/LNG station built adjacent to the gasoline station.
