AUTOMATIC GAS DISTRIBUTION STATION Russian patent published in 2023 - IPC F17D1/04 

FIELD: gas distribution systems.

SUBSTANCE: invention relates to gas distribution systems that can be used in automatic gas distribution stations (AGDS), as well as to the production of liquefied natural gas (LNG). The AGDS contains a gas switching unit from the main gas supply line to the automatic gas distribution station to the main, reserve and bypass lines by means of electric shut-off and control valves of the switching unit. The main and reserve lines include purification units, heat exchangers with coolant heating units and reduction modules, combined into a low pressure line, equipped with a gas commercial metering module at the outlet to the consumer. The bypass line is connected through an electric shut-off and control valve, filter and pressure regulator to the low pressure line and contains an expander connected to the bypass line between the filter and the gas pressure regulator through an additional electric stop and control valve and a gas flow meter. The output from the expander is connected to the LNG collection tank through a valve and a connector for the possibility of connecting and disconnecting this tank for transporting it to the LNG consumer.

EFFECT: expanding the functionality of AGRS.
