GAS-FILLING COMPRESSOR PLANT FOR CHARGING VEHICLE CYLINDERS WITH COMPRESSED NATURAL GAS Russian patent published in 2003 - IPC

FIELD: stationary gas filling stations. SUBSTANCE: proposed gas filling plant contains device to take off gas from mainline, compressor installed in production bay and gas storage accumulator. Gas accumulator communicates with compressor and gas dispensing column mounted in the shed. Gas accumulator is made of coil-type through-pass pipeline mounted on roof of production bay and/or on roof of shed. Said coil is connected with compressor and dispensing column and is furnished with cutoff devices at initial and final sections to prevent getting of gas into coil if leakage appears. Volume of coil exceeds summary volume of gas cylinders of most loaded vehicle, and length of through-pass pipeline exceeds, by the order of magnitude, the summary length of vehicle cylinders. EFFECT: improved safety of accumulators owing to distributor of accumulated energy, better cooling of gas, reduced service expenses. 1 dwg
