FACTS Kollsnes Processing Plant Like an oasis, the processing plant lights up the coastal landscape in late summer evenings. The Kollsnes processing plant plays a key role in the transport of large quanti- ties of gas from fields in the Norwegian sector of the North Sea to customers in Europe. Gas from Kollsnes accounts for around 40 per cent of all Norwegian gas deliveries. The enormous quantities of gas in the Troll field started it all. Today, Kollsnes processing plant acts as goes further treatment and is fractioned Troll is the very corner- a centre for processing of gas from the into propane, butane and naphtha. stone of Norwegian Troll, Fram, Visund and Kvitebjørn fields.
