Trans Austria Gas Pipeline
The Trans Austria Gas Pipeline (TAG ) is a natural gas pipeline that of the Slovak- Austrian border at Baumgarten an der March, where to compensate for supply variability an underground storage is operated by Lower Austria, Burgenland, Styria and Carinthia to the Italian- Austrian border at Arnold Stone leads. The Russian-born natural gas is primarily used to supply the northern Italian industrial districts. But Austrian federal states and Slovenia are supplied.
Background
It consists of a bundle of three cables with a length of about 380 km. Two lines from the 60s ( DAY I and DAY II) from 1 January 2007 by a third, the TAG Loop II adds. The rated working pressure of the three wires is 70 bar. The diameter of the DAY I is 900/950 mm, TAG II has DN 1050 and the TAG Loop II 1000 mm diameter. On 1 October 2008, the transport capacity was increased by about 10%, by two more will be added in Eggen village in Lower Austria and wide village in Styria between the three then existing compressor stations in Baumgarten, Count bei Hartberg and Ruden (Carinthia ).
By September 2008, the following flow rates are now possible and contract awarded ( as of Nov 2007):
- Supply from Russia ( crossover point at Baumgarten ): 4.77 million m³ / h contractually defined cubic meters per hour [ at 20 ° C and 1.01325 bar]
- From delivery: to Italy (transfer point at Arnold Stein): 3.96 million m³ / h
- Slovenia ( turn at wide village; transfer point Murfeld ): 0.45 million m³ / h (from there, via SOL Southeast line of OMV )
- To Austria (different sampling points): 0.36 million m³ / h
According to TAG month workloads were from 90 to 99 % during the colder half of the year and 44-70 % achieved in the warmer over the last three years.
The compressor stations are operated with natural gas engines. In the agreed gas loss "RUN " is therefore also " fuel gas " for the pump included. The quality of gas (natural gas or biogenic) agreed with at least 85 % methane, more than 5 % N2, at most 2% CO2, more than 42 ° C temperature and with an appropriate pressure range.
The pipeline transportation share of total tonne-kilometer transport volume in Austria is high compared to other countries. Transport Discussion cling him almost always, as often ship and rail traffic off the road or cycling and walking, as they are not motorized.
