Verfahren zum Einspeisen von in einer Kavernenspeicheranlage gespeichertem Gas in ein Verbrauchernetz sowie Anordnung zum Durchfuehren eines solchen Verfahrens

摘要

The subject of the invention is represented by a process and a layout for feeding gas stored in a cavern storage facility into a consumer network, in which a high feed-out rate for removal of gas over a protracted period of time can be achieved by means of a multistage procedure by prescribing specific supply line paths between the individual storage caverns and the consumer network to be supplied and by coordinating removal of gas from the individual storage caverns at an originally high storage pressure to a minimum residual pressure which is still below the operating pressure in the consumer network, by means of suitably controlled shut-off valves in the connecting supply line system between storage caverns and consumer network, the only ancillar equipment provided being a compressor station also required for feeding gas into the storage caverns. The gas fed out may also be subjected during its passage through the connecting supply line system to heating by delivery of external heat and to drying to remove the residual moisture content.
