At Mongstad, Statoil is now involved in an oil refinery, an NGL processing plant (Vestprosess), a crude oil terminal, a cogeneration plant and the world's largest technology centre for CO2 capture from flue gases. In terms of tonnage, the port at Mongstad is also the second largest oil and product port in Europe after Rotterdam, with around 1700 dockings per year. A number of other operations have been set up in the Mongstad industrial area, of which the largest is the supply base at Mongstad South. Almost 2000 people are employed here, and around 1100 of them are connected to the operations in which Statoil is involved as a shareholder.
Refinery (Mongstad Refining DA)
The refinery is the largest of the two refineries in Norway, with a capacity of almost 12 million tonnes of crude oil per year. The production at Mongstad far exceeds total operating consumption in Norway and around half goes for export. The plant also produces petroleum coke, which is used for anodes in the aluminium industry. Mongstad Refining DA is 100% owned by Statoil, which is also the operator.
Crude oil terminal (Mongstad Terminal DA)
The crude oil terminal is an important tool for Norwegian exports of crude oil. A large proportion of all Statoil-produced oil on the Norwegian continental shelf, including the State share, is held at the Mongstad terminal for export to customers in North America, Europe and Asia. Oil for the Mongstad terminal comes in mainly through two pipelines from Troll B and Troll C and connected oil fields, and underground storage caverns can store up to 9.44 million barrels. The oil from the Johan Sverdrup field will be brought ashore at Mongstad when production starts towards the end of 2019. MTDA is jointly owned by Statoil (65%) and the Norwegian State (35%), and Statoil is the operator.
Natural gas liquids (NGL) come into Mongstad in pipelines from Kollsnes via Sture. The Vestprosess plant adds value by splitting NGL into naphtha, propane and butane. Naphtha is mainly used for petrol production at the refinery, while propane and butane are shipped out to specialised petrochemical facilities all over the world. Vestprosess is owned by the State (41%), Statoil (34%), ExxonMobil (10%), Shell (8%), Total (5%) and ConocoPhillips (2%), and Statoil is the operator.
Mongstad cogeneration plant
The combined heat and power plant at Mongstad started production in December 2010. The plant was part of the Energiverk Mongstad project, which also laid a gas pipeline from Kollsnes to Mongstad and upgraded the refinery's processing facility. The cogeneration plant is now 100% owned by Statoil, which is also the operator.
The cogeneration plant supplies the refinery at Mongstad with electricity and heat (steam), and under a contract with the holders of the Troll licence, also supplies electricity to the Troll A platform and to the gas processing plant at Kollsnes via the grid.
The purpose of the Energiverk Mongstad project is to enhance the energy efficiency of the Mongstad refinery and improve security of supply for electricity in the region. At maximum utilisation, the cogeneration plant has the capacity to supply 280 megawatts (MW) of electricity and around 350 MW of heat.
The plant consists of two gas turbines, each connected to its own generator for electricity production. Each of these has a separate section to recover flue gas heat. A steam turbine and generator have also been installed. The high-temperature energy obtained from the flue gas is used to heat crude oil which is processed at the refinery. It is also used to produce high-pressure steam which is used as an energy carrier in the processing facilities at Mongstad.
CO2 Technology Centre Mongstad
Mongstad also houses the world's largest technology centre for the development and testing of technologies for CO2 capture. The facility went into operation in i 2013. It is owned and operated by Gassnova (75.1%), Statoil (20%), Shell (2.44%) and Sasol (2.44%).
