The oil refinery at Mongstad in western Norway is a modern highly-upgraded plant with an annual capacity of near 12 million tonnes of crude.
It is the largest facility of its kind in Norway, and medium-sized in European terms.
The refinery belongs to Mongstad Refining, which is owned 79% by Statoil and 21% by Shell.
Most crude oil refined at the plant comes from the Norwegian continental shelf. The principal outputs are petrol, diesel oil, jet fuel and other light petroleum products.
The heaviest components in the feedstock are used to produce such products as petroleum coke (petcoke), an important raw material for the anodes required by Norway’s aluminium industry.
Petrol production at Mongstad corresponds to 1.5 times Norwegian consumption.
Most of the refinery’s output is exported, particularly to continental Europe.
The oldest part of the Mongstad facility was constructed in the early 1970s. An expansion in 1989 increased annual refining capacity from 6.5 million tonnes of crude to 10 million. Because of the power plant, the capacity increased further up to near 12 million tonnes in 2011.
A new desulphurisation plant for diesel and gas oil was inaugurated at the complex in March 1996, with a facility for reducing the benzene content following in the autumn of 1997.
These installations ensure than the relevant products from Mongstad meet the latest European Union standards.
A desulphurisation plant for petrol completed in the spring of 2003 again allowed the refinery to meet new EU specifications from 2005.
Statoil also operates a crude oil terminal at Mongstad, with a storage capacity of 9.5 million barrels.
Mongstad ranks as Norway’s largest port in tonnage terms, and the second-largest European oil port after Rotterdam in the Netherlands.
