Natural gas reservoir Haidach successfully put into service
On 3 July 2007, Chemieanlagenbau Chemnitz GmbH (CAC) handed over the largest natural gas reservoir in Austria and second largest reservoir in Central Europe to its operator! The unit has been designed, erected and commissioned within a record time of just two years by order of Rohöl-Aufsuchungs AG.
The scope of services of CAC included basic and detail engineering, procurement (on behalf and for account of the customer), supervision of construction and erection as well as commissioning. In the 1st expansion stage, the reservoir has a gas storage capacity of 1.2 billion m³ with a gas throughput of up to 500,000 m³ / h.
The storage system is characterised by a high degree of automation and comprises such essential components as a compressor station, gas-drying unit and facilities for separating liquids and solids from the gas stream.
The operation of the reservoir takes place largely without any attendance and is monitored by a control centre. This and plant pressures up to 180 bar necessitate compliance with highest safety and environmental standards.
The commissioning of this reservoir represents a significant milestone in the efforts made to ensure a reliable energy supply in Europe. It is planned to expand the reservoir in a 2nd expansion stage. All essential requirements existing in regard of this expansion have already been taken into account. Once this second expansion stage has been completed in April 2011, the reservoir will be able to store up to 2.4 billion m³ natural gas.
