refining and marketing

Sulphur-free diesel
The refinery delivers ”eco-diesel” in all qualities, including almost sulphur free ”eco-diesel” with less than 0.001 percent sulphur content.

Environmental performance
The refinery unfortunately had three discharges of oil to the ground due to the internal reporting demand of one barrel (160 litres) in 2008. All other discharges to water and air were within the limits determined by the State Pollution Agency (SFT). The yearly report on the environment and social responsibility gives details on emissions and the environmental work at the refinery.

Inspection and rehabilitation of pipe systems on quay and tank park
A comprehensive work program including risk assessment, inspection and rehabilitation of the pipe systems has been ongoing since 2001. The cost of the program is estimated at more than NOK 75 million.

Energy and climate gases
International comparisons show that the ExxonMobil refinery at Slagentangen is one of the most efficient refineries in the world in terms of efficient use of energy. Since the early 1990s, the refinery has implemented internal measures to save energy, and the use of energy today is 25% more efficient than it was in 1990. The reason why CO2 emissions nevertheless have increased during this period, is mainly due to new environmental requirements to products, i.a. increased desulphurization. Furthermore, the refinery has increased its processing capacity for crude oil.
