Trans Austria gas pipeline

from Wikipedia, the free encyclopedia

The Trans Austria Gas Pipeline (TAG) is a natural gas pipeline that runs from the Slovakian- Austrian border near Baumgarten an der March , where an underground storage facility is operated to compensate for fluctuations in delivery , through Lower Austria , Burgenland , Styria and Carinthia to the Italian-Austrian border near Arnoldstein leads. The natural gas, which comes from Russia , is mainly used to supply the northern Italian industrial areas, Austrian federal states and Slovenia.

background

The TAG consists of three lines with a length of approx. 380 km each. Two lines from the 1960s / 1970s (TAG I and TAG II) were supplemented by a third, the TAG Loop II, from January 1, 2007. The nominal operating pressure of all three lines is 70 bar. The diameter of the TAG I is 900/950 mm, the TAG II is DN 1050 and the TAG Loop II is 1000 mm. On October 1, 2008, the transport capacity was increased by around 10% by installing two more at Eggendorf in Lower Austria and Weitendorf in Styria between the three existing compressor stations in Baumgarten, Grafendorf near Hartberg and Ruden (Carinthia) .

Until September 2008 (as of November 2007) the following flow rates were possible and contractually awarded:

  • Infeed from Russia (takeover point at Baumgarten): 4.77 million m³ / h contractually defined cubic meters per hour [at 20 ° C and 1.01325 bar]
  • from it delivery:
    • to Italy (transfer point at Arnoldstein ): 3.96 million m³ / h
    • to Slovenia (junction at Weitendorf ; transfer point Straß ) via south-east pipeline (SOL): 0.45 million m³ / h
    • to Austria (various withdrawal points): 0.36 million m³ / h

According to TAG, monthly occupancy rates of 90 to 99% were achieved in the colder half of the year and 44 to 70% in the warmer half of the year.

The compressor stations are operated with natural gas engines. The agreed gas loss "LAUF" therefore also includes "fuel gas" for pumping. The gas quality (natural gas or biogenic) is agreed with a minimum of 85% methane, a maximum of 5% N 2 , a maximum of 2% CO 2 , a maximum temperature of 42 ° C and a suitable pressure range.

The TAG's direction of flow is typically south-west. Technically, however, the TAG can be operated bidirectionally, i.e. optionally in both directions.

The stations

The stations of the TAG in the south-west direction are according to TAG GmbH - status 2007/2015:

Since June 1, 2013, a geocache has been luring its hunters to the Weitendorf compressor plant.

  • TAG facilities and marks on the surface

  • Gate valve station in Hollenegg , Southwest Styria

  • Hollenegg gate valve station

  • The routes of the gas and oil pipelines are parallel in the Gleinztal near Unterbergla

  • Identification of the route of DAY II and III in the Gleinztal

  • DAY I at the upper glassworks, Soboth

Operator and owner

The TAG is operated by Trans Austria Gasleitung GmbH. Its shareholders are (as of November 2015) the Italian Snam with a stake of 84.47% (since December 19, 2014 - previously CDP GAS Srl) and Gas Connect Austria with a stake of 15.53%.
