Sweden's largest transportation fuel producer, Preem AB has, together with global refinery technology provider Haldor Topsoe A/S, concluded the hydrotreater revamp of Preem’s Gothenburg refinery. The duo has achieved 85 percent co-processing of renewable feedstock and continues to advance the field of renewable fuel production.
At its Gothenburg refinery, Preem uses tallow and raw tall diesel, a refinery ready bio-feedstock produced from the pulp industry by-product crude tall oil (CTO), as the main feedstocks.
This is the second revamp of the hydrotreater, following a revamp in 2010 that upgraded the unit to co-process 30 percent renewable feedstock using Haldor Topsoe’s HydroFlex technology.
The unit was one of the first in the world capable of processing renewable feedstock.
This second revamp with Preem demonstrates our leading capabilities to enable our customers to use renewable feedstocks to produce a cleaner diesel product. We are pleased to support Preem in their ambitious 2030 goal to produce even more renewable fuels in order to reduce carbon emissions, said Amy Hebert, Chief Commercial Officer at Topsoe.
The revamp of the refinery is a significant step in a long-term plan for Preem with the goal to produce five million m3 of renewable fuels by 2030. This means reducing carbon emissions by 12.5 million tonnes.
The revamp means that Preem has increased Sweden’s domestic production of biofuels and thereby is contributing to the ongoing shift from fossil fuels to renewables. This takes us one more step towards our goal of producing five million cubic meters of renewable fuels by 2030, said Aad van Bedaf, EVP Refining at Preem.
Collaborating on Lysekil refinery revamp
Preem and Topsoe are also collaborating to revamp the Synsat unit at Preem’s Lysekil refinery. This unit will benefit from Topsoe’s HydroFlex technology to produce clean renewable diesel based on various renewable feedstocks, including rapeseed oil.
The unit is scheduled to be fully rebuilt by 2024. The revamp will support Preem with 950 000 m3 per annum of renewable diesel securing 40 percent co-processing.
As part of the revamp, the Synsat unit will be prepared to process 100 percent renewable feedstock.
