Definitions

  • the invention relates to a method and apparatus for storing fuel gas, in particular methane (natural gas), as well as, for example, from the WO 03/07991 are known.
  • the natural gas demand of private and industrial consumers is characterized by seasonal and daily fluctuations.
  • Natural gas storage facilities are operated to compensate for the fluctuations in consumption.
  • To cover the peak consumption in particular to cover the high natural gas demand for heating purposes at low winter temperatures correspondingly high capacities are provided in gas transmission networks municipal gas supplier.
  • large underground natural gas storage facilities for buffering consumption peaks such as tube storage and ball container are known.
  • the capacities of the latter gas storage are limited to several hours Eintechnisch- or Aus Grandezeit and therefore suitable only to compensate for daily consumption fluctuations.
  • the specific investment costs of such gas storage are high.
  • the supply of natural gas is therefore burdened with a relatively high transport or performance price.
  • conventional gas storage relatively large volumes and thus a lot of space.
  • the present invention has for its object to provide a method and an apparatus that allow a more cost-effective gas supply, especially natural gas supply.
  • the invention has for its object to provide a method and an apparatus that allow space-saving gas storage.
  • the invention proposes a method for storing fuel gas, in particular natural gas (methane), in which compressed fuel gas supplied by means of a supply line, in particular natural gas, is divided by means of a dividing device into a first partial gas stream and at least one second partial gas stream, in which the first partial gas stream is expanded by means of at least one working machine, in particular an expansion turbine, wherein the first partial gas stream is previously heated by means of at least one heat exchanger so that this partial gas stream after relaxation in the at least one working machine a temperature still above 5 ° C, preferably greater than or equal to 8 ° C, in which the second partial gas stream is compressed by means of at least one compressor driven by the at least one working machine, heat dissipated in the second partial gas stream by its compression being removed and being used to heat the first Gas partial flow is used in the at least one heat exchanger, in which the compressed, cooled by heat removal second partial gas stream is so far relaxed that at least 10%, preferably more than 50% of the second partial gas stream incurred in the liquid state, and in which
  • the first partial gas stream is preferably introduced into a municipal supply network.
  • the device according to the invention accordingly comprises a dividing device for dividing compressed, supplied by a supply line fuel gas, in particular natural gas, in a first partial gas flow and at least one second partial gas flow, at least one working machine, in particular an expansion turbine, for relaxing the first partial gas flow, at least one compressor for compressing the second partial gas flow, wherein the compressor is driven by the at least one working machine, at least one heat exchanger, which transfers heat, which arises in the second partial gas flow by the compression thereof, to the first gas partial flow before its expansion in the at least one working machine, at least one expansion device for relaxation and at least partial liquefaction of the compressed, cooled by heat removal second partial gas flow, and at least one heat-insulated container for storing fuel gas liquefied by means of the expansion device.
  • a dividing device for dividing compressed, supplied by a supply line fuel gas, in particular natural gas, in a first partial gas flow and at least one second partial gas flow
  • at least one working machine in particular an expansion turbine
  • the compressor for compressing the second partial gas
  • heat exchanger can also be used in the present context, the term "heat exchanger”.
  • An essential feature of the invention is the use of one or more heat exchangers to use the heat generated in the one partial gas flow during the compression, for the heating of the other, relaxing gas partial flow, and the drive of the at least one compressor by the at least one Working machine, by means of which said partial gas stream is expanded.
  • part of the pressure energy of the compressed fuel gas supplied via the supply line (high-pressure line) is used for the further compression and liquefaction of a partial gas stream.
  • the coupling according to the invention of the at least one compressor with the at least one working machine (for example expansion turbine) which relaxes the other partial gas stream does not require any additional drive energy, which is economically advantageous.
  • Another economic advantage of the invention is that it does not require any additional heat energy, which is usually required to heat (heat) natural gas as it is being expanded from a high pressure supply line to medium or low pressure for further distribution to prevent possible icing of the expansion plants due to the Joule-Thompson effect.
