Case study highlighting the benefits of monitoring and control for improving the performance of an anaerobic digestion plant.
The biogas / biomethane plant is located in an arable region approximately 40km to the east of Vienna in the federal state of Lower Austria in the eastern part of Austria. The biogas plant is operated as a co-digestion plant and utilizes organic waste material to a high extent for the production of a high-quality biogas. The plant has been commissioned in the year 2004 and initially produced electric power and heat for the local district heating grid using CHP-gas-engines. In the year 2007 the biogas plant has been complemented by the erection and commissioning of a biogas upgrading plant producing biomethane for natural gas grid injection. A part of this gas is consumed in the local low-pressure grid; the remaining part (especially in summer and during the night) is compressed to 60bar and injected into the regional high-pressure gas grid. The manufacturer of the upgrading system was Axiom Angewandte Prozesstechnik GmbH, the complete biogas / biomethane production facility is operated by Biogas Bruck/Leitha GmbH.
