Process technology specialist Topsoe has been selected to provide its HydroFlex technology for Swedish fuel company Preem’s renewable fuels plant near Lysekil.

The project involved a revamp of a major IsoCracker (ICR) unit at the Preemraff Lysekil refinery, Topsoe said on 23 January.

Scheduled to start up in 2027, the unit would produce 1.2M m³/year – 22,000 bpd (barrels/day) – of sustainable aviation fuel (SAF) and renewable diesel once operational, Topsoe said.

“The demand for sustainable aviation fuels is increasing rapidly, and we are already in dialogue with several major airlines. With this investment, Preem takes another … step in the transition from fossil to renewable production,” Preem director of sustainable development Peter Abrahamsson said.

Designed for the production of renewable jet fuel and diesel, Topsoe said its HydroFlex technology could be used to convert fats, oils and greases in both grassroots units and revamps for co-processing or stand-alone applications.

Headquartered in Denmark, Topsoe is a developer and supplier of decarbonisation technology, catalysts, and services for the energy transition sector.

In addition to the Preemraff Lysekil refinery, Preem has a refinery in Gothenburg – Preemraff Göteborg – and the two plants have a combined refining capacity of more than 18M m³/year.

The Stockholm-based company exports its products to the international market, mainly northwestern Europe.

The partnership built on years of cooperation between the two firms to produce renewable fuels, including at Preem’s refinery in Gothenburg, Topsoe said.

Preem has a long-term target of producing 5M m³/year of renewable fuels and achieving a climate neutral value chain by 2035.
