Natural gas compressor station for exploiting sour gas fields with declining gas pressures. The Hespenbusch compressor station increases the operating pressure of the natural gas to be conveyed to the processing plant in Grossenkneten.

The aim of the project was to keep the production rate of the depleted sour gas fields of Harpstedt, Neerstedt, Brettorf, Brinkholz, Döttlingen, Varnhorn, Rechterfeld, Quaadmoor and Wöstendöllen stable in times of declining pressures.

Technical data:

• Compressor type: 2 turbo compressors (1 ND and 1 HD compressor), parallel
• Compressor drive: electric motor with frequency converter
• Power: 2 x 7 MW (output at the compressor drive shaft: max. 5.5 MW each)
• Throughput: 35,000 - 180,000 Nm³/h
• Suction pressure: 10 - 38 bar
• Discharge pressure: 77 - 80 bar
• Pipeline - suction side: 3 pipelines with diameters of 16", 17", 20"; discharge side: 1 pipeline with a diameter of 16"
