Kårstø gas processing plant

Kårstø processing plant north of Stavanger plays a key role in the transport and treatment of gas and condensate (light oil) from central parts of the Norwegian continental shelf.

This facility separates the rich gas arriving in the Statpipe and Åsgard Transport pipelines into its various components. It also handles unstabilised condensate piped from the Sleipner area.

These flows yield methane, ethane, propane, iso and normal butane, naphtha (natural gasoline) and stabilised condensate.

Dry gas – methane and some ethane – is transported on through Statpipe dry gasand Europipe II, while the natural gas liquids and condensate are exported by ship.

Kårstø ranks as one of the world’s largest producers of liquefied petroleum gases – propane and butanes – and this LPG is shipped to customers world-wide.

Propane is stored in two large artificial rock caverns with a combined capacity of 250 000 m3. Ethane, normal and iso butane, naphtha and stabilised condensate are held in tanks.

First gas reached the complex on 25 July 1985 through a pipeline from the Statfjord field in the North Sea, and the first dry gas was piped on to Emden in Germany on 15 October that year.

Kårstø runs primarily on fuel gas. Five of its nine compressors use this energy source, while the remaining four are electrically powered.
