In the low temperature liquefied gas storage tank for storing plural liquefied gases such as oxygen and nitrogen and supplying the gases to medical institutions and various factories, the space for the construction site can be reduced, and the isothermalization of each liquefied gas is carried out. We plan and preserve reliable gas supply by the demand line.n n n The inner tank 4 is disposed in the outer tank 2 in a plurality of upper and lower stages via the heat insulating layer 3 to effectively use the paper.n n n In addition, the liquefied gas LG 1 , which is a high boiling point of the upper inner tank 4a, is cooled by supplying the liquefied gas LG 2 , which is a low boiling point of the lower inner tank 4b, by the heat exchanger 11, and The internal pressure is stabilized to suppress the fluctuation of the internal pressure caused by the fluctuation of the consumption of gas G 1 with respect to the demand line in the upper inner tank 4a, thereby making it possible to maintain the stable supply. |
