Abstract

산소나 질소등 복수액화가스를 저장해서, 그 가스를 의료기관이나 각종 공장등에 공급하기 위한 저온액화가스 저장탱크에 대해, 그 건설용지의 스페이스 절약화를 도모할 수 있고, 각 액화가스의 등온화를 도모하여, 그 수요선으로 확실한 가스공급을 보전한다.
외측탱크(2)내에 상하 복수의 단으로 내측탱크(4)를 단열창(3)을 개재하여 배설하여 용지를 유효하게 이용한다.
또한 상부의 내측 탱크(4a)고비들점인 액화가스(LG1)를 열교환부(11)에 의하여 하부의 내측탱크(4b)의 저비등점인 액화가스(LG2)의 공급에 의하여 정온화시키는 것과 그 내부압력을 안정시켜, 상부의 내측탱크(4a)에서의 수요선에 대해 가스(G1)의 소비량 변동이 따르는 내부압력의 변동을 억제해서, 그 안정공급을 보전가능하게 한다.
