FIELD: machine building.
SUBSTANCE: proposed system comprises buried tank 1 with liquefied hydrocarbon gas equipped with automatic control and safety system 9, pipeline of liquefied gas vapor phase composed of internal gas discharge pipe 2, buried gate valve 3 to shutoff soil evaporator in repair, steam superheating pipeline 4 composed of helical horizontal pipeline arranged under the depth of seasonal soil frost penetration, box-type gas control station 5 and low-pressure regulator 6 accommodated therein. Note here that said station 5 is equipped with low-pressure vapor phase gas line.
EFFECT: ruled out formation of liquefied hydrocarbon gas hydrates in pressure regulator orifices.
