Preem ascertains position as one of the world’s prime producers of green diesel

Preem is yet again at the forefront of environmental and technological advancement on a global scale. Based on Swedish innovations, Preem has reconstructed a substantial part of one of the company’s two refineries in Sweden into a fully-integrated green refinery, producing a new type of MK-1 (MK-1 is rated as first-class environmentally friendly diesel) based solely on renewable sources.

Being the largest oil company is Sweden, Preem plays an important role in creating solid grounds for sustainable development. Preem’s refining capacity exceeds a yearly 18 million m3 crude oil. The two refineries in Gothenburg and Lysekil are among the most modern, environmentally-friendly in Europe and the world.

From crude oil to a wide focus on renewables
By reconstructing parts of the refinery based in Gothenburg into a production unit for green diesel, Preem stresses its ambitions further. “This is a natural step for us in achieving our long-term ambition integrating more renewable sources into our main produce”, Thomas Ögren, Communications Manager at Preem, explains. He continues:
“This is also as far as we know the first crude oil refinery in the world being converted into a bio-refinery. Renewable products are integrated at the very core of the production process. We are currently primarily using bi-products generated from the Swedish forestry industry. Other biodegradable products and plant-based oils such as rapeseed oil can also be used to manufacture the new green diesel”.
Preem is the main supplier of MK-1 diesel in Sweden. MK-1 has a sulfur content of less than 5 ppm (parts per million), significantly lower than the maximum European tolerance of 50 ppm. By introducing green diesel Preem has established a unique standing point. The ambition is to develop this strategy further, and Preem has made other significant investments to promote environmental sustainability.

Maintaining sustainable collaborations
Preem has in close collaboration with Volvo Lastvagnar and Chemrec AB established the first station for BioDME at Kungens kurva, Stockholm. BioDME generates up to 95 per cent fewer emissions in comparison to standard diesel types. “This is our first step with BioDME. In the near future, additional stations are planned for Gothenburg, Jönköping and Piteå”, Ögren reveals.
Preem also maintains long-term collaborations with Chalmers University of Technology, Gothenburg, promoting new innovations and research within the area of environmentally-friendly fuels.
“We have recently renewed our contract with Chalmers, stating that we will continue to work closely over the next three years in the process of developing new techniques for more efficient ways of using energy-generating resources”, Thomas Ögren concludes.
