The invention relates to equipment intended for storage of liquefied gas, and can be used in the fuel and energy industry, for example, gas-filling stations.

In the prior art it is known storage for liquefied gas containing underground sprinkled tank [B. C. Rachevsky, S. M. Rachevsky, I. I. Radzik. Storage of liquefied hydrocarbon gases. M.: Nedra, 1974, pages 128-136]. The specified repository consists of a ground cylindrical tank having a filling soil not less than 0.2 m above the fluid level in the tank and not less than 6 m from the tank wall to the edge of the surfacing. The tank consists of a cylindrical body and two Ellas the measuring means. And for selection and input of liquefied gas is the same pipe.

To obtain the desired technical result in the above solution prevents the high metal structure, due to the need of a large number of pipelines, which in turn, lowers industrial safety equipment. Moreover, the size of the mound requires quite a large area.

The selection of liquefied gas through the pipe 6 selection of liquefied gas. To do this, the pipe 13 to the vapor phase, for example with the aid of the compressor in the upper part of the cavity of the tank 1 creates excessive pressure because the area of the nozzle 13 located inside the tank 1, is located above the maximum level of the liquid phase of the liquefied gas. During operation of the tank 1 near the bottom of the tank can accumulate various impurities.
