ADSORPTION SYSTEM OF REVERSIBLE ACCUMULATION OF VAPORS OF LIQUEFIED NATURAL GAS Russian patent published in 2022 - IPC F17C5/02 F17C11/00 F17D1/02 

FIELD: gas industry.

SUBSTANCE: invention relates to the field of storage of natural gas in a combined state: liquefied and adsorbed. The system includes a liquefied natural gas tank, a cryogenic liquefied natural gas extraction pump, a liquefied natural gas vapor storage adsorber filled with adsorbent, a liquefied natural gas regasification unit, liquefied natural gas vapor utilization lines, gas delivery to the consumer, natural gas extraction from the storage adsorber. The storage adsorber of liquefied natural gas vapors filled with adsorbent is connected to the liquefied natural gas reservoir through the liquefied natural gas vapor recovery line and the check valve of the liquefied natural gas vapor recovery line. With the consumer, through the natural gas extraction line from the storage adsorber. The storage adsorber contains an internal heat exchanger connected to the gas supply line to the consumer through the first and second shut-off valves of the storage adsorber heat exchanger. The internal heat exchanger of the storage adsorber is located in the gas supply line to the consumer after the cryogenic liquefied natural gas extraction pump and before the liquefied natural gas regasification unit. The natural gas extraction line from the storage adsorber contains a filter. The gas supply line to the consumer contains a bypass line with a shut-off valve bypassing the storage adsorber and shut-off valves for supplying liquefied natural gas to the heat exchanger of the storage adsorber.

EFFECT: increase in the efficiency of adsorption accumulation of vapors of liquefied natural gas.
