METHOD OF AND DEVICE FOR STORING NATURAL GAS Russian patent published in 2005 - IPC

FIELD: gas industry.

SUBSTANCE: invention relates to method of storing natural gas for satisfying peak requirements. According to invention, hermetic sleeve, diameter 10-12 m and 400-600 m long, is made of sheet reinforced polyethylene, thickness 0.3-0.5 mm. High-pressure reinforced hose is fitted at one end of sleeve. Flattened sleeve is lowered to bottom of sea or lake to depth of 2-4 km, with laying of high-pressure hose along bottom to beach or floating station. Sleeve is covered by rope net, and granite stones are placed at sides to equalize buoyancy force. Gas under pressure of 200-400 atm is pumped into sleeve to turn it into cylindrical reservoir-storage, capacity of -60 thousand cubic meters. Reservoir is enclosed by rope net to prevent floating up. Gas is consumed from storage by natural forcing by bottom pressure of water. Proposed device for storing natural gas consists of compressing and transfer station, high-pressure pipeline, elastic reservoir, rope net and granite ballast. Compressing station is installed on the beach or afloat on sea or lake surface and is connected at bottom by high-pressure pipeline with elastic storage-reservoir enclosed by rope net and arranged at depth of 2-4 km.

EFFECT: possibility of storing gas compressed to 400 atm in modular thin walled reservoirs.
