The Statoil refinery at Kalundborg in Denmark refines crude oil and condensate (light oil) to petrol, jet fuel, diesel oil, propane, heating oil and fuel oil.
Countries around the Baltic represent the principal market for products from the refinery.
Annual production capacity at Kalundborg is close to 5.5 million tonnes of oil products, depending on the type of feedstock.
The oldest part of the refinery was built in 1961. After an expansion in 1995, it can accept a larger proportion of condensate. That in turn allows it to produce petrol with a lower content of benzene, a carcinogen.
Deliveries of petrol with only 1% benzene to the Danish market started in 1997.
The refinery began to produce agricultural fertiliser in 2000, utilising a completely new facility designed in cooperation with Denmark’s Haldor Topsøe Ltd.
This plant converts sulphur and nitrogen from the desulphurisation process for oil products into liquid ammonium thiosulphate (ATS).
The result has been a substantial reduction in emissions of sulphur and nitrogen oxides from the refinery.
Built at a cost of DKK 400 million, the Synflex facility came on stream in the summer of 2002 with an annual capacity of about one million tonnes of sulphur-free diesel oil (defined as 10 parts per million of sulphur, or 0.001%).
Kalundborg also delivers petrol and diesel oil with less than 50 ppm (0.005%) of sulphur.
The refinery primarily processes various crude oils and condensates from the North Sea, which are brought in by ship.
Condensate comes chiefly from the Sleipner area via Statoil’s gas processing plant at Kårstø north of Stavanger.
Kalundborg cooperates with other local industrial companies over exchanging energy and on commercial exploitation of each other’s used coolant water and waste products.
Termed an industrial symbiosis, this collaboration was rewarded with the Danish Environmental Prize in 1991.
