The Kalundborg refinery in Denmark is owned by Equinor Refining Denmark A/S. It is Denmark's largest oil refinery, processing about 5.5 million tonnes of crude oil and condensate per year. The plant has a tank capacity of some 800 million litres. Equinor, formerly known as Statoil, purchased the refinery from Dansk Esso A/S in 1986.

How to find us in Denmark

The oldest parts of the refinery were put into use in 1961, and the plant has been gradually developed since then. In 1995 a condensate distillation plant was added, enabling the refinery to receive a large amount of condensate, a light crude. It was thus possible to produce high value products.

Equinor Refining Denmark A/S produces gas, naphtha, petrol, diesel, fuel oil and heavy fuel, and the primary markets besides the Danish market are Scandinavia and northwest Europe.

The refinery mainly processes various crude oils and condensate from the Norwegian continental shelf, but also receives crudes, e.g., from West Africa.

All crude oil and condensate are transported to Kalundborg by tankers, and most of the completed products are also transported by sea. There are a total of about 625 shipping arrivals per year, and Equinor Refining Denmark A/S therefore has a harbour in connection with the plant.
