The plant at Kollsnes was opened in 1996 and plays an important role in exports of gas to Europe from the Norwegian continental shelf, with approximately 40% of all Norwegian gas export going via this facility.
At Kollsnes the wet gas (NGL, natural gas liquids) is separated from the gas, and the resulting dry gas is compressed before large delivery compressors inject it into the pipeline systems which supply the gas to customers.
Kvitebjørn and Visund
In 1999 it was decided to bring the gas from Kvitebjørn ashore at Kollsnes, and the gas from this field has a composition that makes it suitable for processing into higher-grade products.
Following this decision, a new plant was built to extract wet gas from the rich gas from Kvitebjørn. The new plant ushered in a new era at Kollsnes when it went into operation on 1 October 2004. Since October 2005, gas from the Visund field has also been brought ashore at Kollsnes. With a capacity of 26 million Sm3 of gas per day and great flexibility, the new NGL facility can also refine gas from future fields as they are developed.
The Vestprosess pipeline connects the facilities at Kollsnes to those at Mongstad, where wet gas from Kollsnes is fractioned into propane, butane and naphtha.
