摘要： The invention solves the problem of energy-free compensation of fluctuations in gas demand in natural gas networks by means of a compression-storage-expansion installation by using a reciprocating compressor (5) driven by gas taken from a medium or high pressure transmission pipeline.
The compression-storage-expansion installation may additionally have a gas liquefaction module based on gas expansion (14) and at least one low-temperature tank (17) and a liquid gas evaporator (19).
Moreover, it may have measuring-distribution sets for delivering compressed and/or liquefied gas as respectively CNG (12) and/or LNG (20) fuel to the external customers.
