In Sweden, Alleima will supply Preem with heat exchanger tubes to be used in the conversion of the Lysekil refinery from fossil to renewable fuels. The investment is an important part of Sweden’s green energy transition and will make Preem the largest producer of renewable jet fuel in northern Europe. The redevelopment of Preem’s IsoCracker plant (ICR) in Lysekil started late 2024. Once completed, it will produce 1.2 million cubic meters of renewable fuels annually and reduce fossil carbon dioxide emissions at user level by 2-3 million tons annually. “Reducing greenhouse gas emissions is one of the great challenges of our time. I am therefore proud that Preem is now making the biggest change in the company’s history. We are doing this by converting the diesel plant at the refinery in Lysekil. When the conversion is complete, we will be Scandinavia’s largest producer of renewable jet fuel,” said Tommy Johansson, project manager for the ICR project at Preem. The changeover means that Preem will no longer use fossil raw materials such as crude oil, but renewable raw materials instead. To make this possible, advanced technology is required, not least in the pre-treatment unit (PTU) that is to be built. The raw materials will be pre-treated and purified at high temperatures before being used in the production of renewable fuels such as Hydrotreated Vegetable Oil (HVO), the diesel made from vegetable oils or plant products and SAF, the company said.
