Compressor station

A compressor station (including compressor station ) is an investment in a gas pipeline in which a compressor compresses the gas again to compensate for pressure losses.

The natural gas is conducted from the gas fields after preparation via pipeline to consumers. Remember Dines it is at high pressure and due to the loss of flow reduces the pressure in the pipeline. Therefore, it is necessary to compress the gas in the compressor stations.

Construction of a compressor station

  • Prime mover; This drives the compressor, has as an energy source in most cases natural gas, consisting of small units ( less than 1 MW engine power) mainly in a (piston ) gas engine, and for larger more from a gas turbine ( 1 to 30 MW engine power). Almost always there are two or more prime movers at a compressor station ( see N 1 redundancy )
  • Since 2010 and 2011 respectively centrifugal compressor run with gearless, oil -free magnetic bearings, electric motor drive quieter than conventional gas turbines in Neustift / Oberkappel (WAG West-Austria -Gas-Pipeline ) and Baumgarten (Lower Austria, three each with 6 MW).
  • Waste heat recovery; the prime mover. Today, this is not provided at each compressor station, but at TAG - compressor station in Weitendorf such a system of OMV Gas & Power is in operation at the system uses the heat and from up to 16 MW of electrical power is generated without producing additional CO2.
  • Transmission unit; this compensates for the speed of the engine to the compressor.
  • Compressor; this sucks the gas from the pipeline, and feeds it thickens again.
  • Cooler; during compression the gas is heated and has to be cooled on the one hand hot gas has a lower density and thus a higher pressure loss, on the other hand, the high temperature damage to the moisture isolation of the pipeline.

The compressor stations, so for example, on the Trans- Austria gas pipeline, about 100 km are located. The demand for natural gas for driving the compressor stations is strongly dependent on the operating condition and the design of the pipeline system, since the pressure loss is the square of the flow velocity. In the overload operational status of the pipeline of up to 1% of the transported amount per 100 km; in the full load condition around 1% per 250 km, whereas in the 10% part load condition only 1% for approximately 10000 km ( typical numbers).

Small plants have in buildings the size of a prefabricated garage space, large plants occupy a facility the size of a factory building.

Examples

  • Stutensee - Blankenloch
  • Großenkneten
  • Roth town, station of the Central European Gas Pipeline ( MEGAL )
  • Waidhaus, import point of the Central European Gas Pipeline ( MEGAL )
  • Mittelbrunn, station of the Trans -Europe natural gas pipeline
  • Sidon in the Ore Mountains
  • Baumgarten an der March, the station for several major pipelines, including West-Austria -Gas-Pipeline (WAG)
  • Mallnow, import point of JAGAL, operated by WINGAS
  • Reckrod, intersection of STEGAL and MIDAL WINGAS
  • Gernsheim, the MEGAL station consisting of four units. These units consist of a compressor manufacturer C65 Solar Turbines and as a direct drive to a gas turbine of the type titanium 130 (2x) or Mars (2 x ) of the same manufacturer. The line pressure is increased from 58 bar to 74.5 bar.
  • Wardenburg, station of the Northern German Gas - Transversal ( NETRA )
