Abstract

이 논문에서는 특례기준에 따라 국내에서 최초로 제작하고 검사한 LNG 탱크 컨테이너를 이용하여 육상 및 해상 운송 시연사업을 하고, 탱크 컨테이너를 운송할 때 탱크 컨테이너 내부에 충전된 LNG의 압력변화와 탱크 컨테이너의 실제 압력유지기간을 측정하였다. 탱크 컨테이너 내부의 압력은 충전 직후에는 급속하게 상승하고, 탱크 컨테이너를 이동할 때 급속히 하강하나, 일정시간이 경과한 후에는 기액평형상태 그래프의 온도-압력 변화와 일치함을 확인하였다. 또한, 탱크 컨테이너의 실제 압력유지기간은 특례기준에서 규정한 20일 이상을 만족함을 확인하였다. Internal pressure variation analysis and actual holding time test on ISO LNG tank containers which were made in Korea for the first time according to the special notification of ISO tank container manufacture have been conducted during the transport demonstration projects of the tank containers by tractor, train and ship. The internal pressure of the LNG tank container increased rapidly after LNG filling and dropped during moving the container. However, it was stabilized as time passed and followed the liquid-vapor equilibrium graph. In addition, actual holding time of the tank container was more than 20 days which was satisfied with the special notification of LNG tank container manufacture.
