Kollsnes

Kollsnes is a natural gas processing plant operated by Equinor on the southern part of the island of Oøy in Øygarden Municipality in Vestland county, Norway. It processes the natural gas from the Troll, Kvitebjørn, and Visund gas fields. Kollsnes has a capacity of 143,000,000 m3 of natural gas per day.

Operation
At Kollsnes, the Natural gas liquids (NGL) are separated out of the gas. The dry gas is compressed and then shoved by large compressors out in the pipe systems that transport it to the customers. In 1999, it was decided that the gas from Kvitebjørn was to be landed at Kollsnes. The consistency of the gas from the field made it well suited to be reprocessed to upgraded products. The new plant that was built cost NOK3 billion, with operations starting on 1 October 2004. Starting in October 2005, the gas from Visund is also landed at Kollsnes. With a capacity of 25,000,000 m3 gas per day and large flexibility, the new NGL plant can process gas from new fields that would be built.

Though the Vestprosess gas pipeline, the plant at Kollsnes is linked to the plants at Mongstad, where the NGL from Kollsnes is fractioned into propane, butane, and naphtha. The gas from Kollsnes is transported through the four pipe systems Statpipe, Zeepipe, Europipe I, and Franpipe to continental Europe and supplies Austria, Belgium, France, Germany, the Netherlands, Spain, and the Czech Republic with gas. The pipes are owned by Gassled, operated by Gassco while the technical responsibility is handled by Equinor.

Power Consumption
In 2009, the electric power consumption of the plant was 2000 GWh per year. This had increased from 1000 GWh per year in 1996.
