Wärtsilä to extend existing biogas plant to produce 45 tons of bioLNG per day

Technology group Wärtsilä  has announced it will supply, install, commission and start-up the biogas upgrading and liquefaction units for a Swedish bioLNG plant.
The new plant is an extension of an existing biomethane and bioLNG plant supplied previously by Wärtsilä, and will bring the production of bioLNG from 20 to 45 tons per day.
The plant, located in Linköping, is owned by Tekniska Verken, a municipality-owned company.
The order with Wärtsilä was booked in Q4, 2023.
The Wärtsilä processing solution includes its patented VAC vacuum technology option in the upgrader, which offers greater flexibility for the heat supply to the upgrader. This allows the customer to supply the needed process heat from their own district heating network.
"By expanding our capacity for biomethane in both gaseous and liquid form, we are complementing our existing upgrading and liquefaction plant, as well as continuing to contribute in the journey towards our vision of becoming the world's most resource effective region.
"Our experience with the existing Wärtsilä plant has been positive, so we are looking forward to this extension project," said Anna Lövsén, CEO Svensk Biogas and Business Area Manager, Biogas, Tekniska Verken.
"Tekniska Verken is in the forefront of producing and promoting bioLNG in Sweden, and we are honoured to have been selected to further extend their existing plant.
"Our corporate policy is to enable decarbonised operations wherever possible, and we look forward to delivering another high performance process solution," commented Magnus Folkelid, sales manager biogas, Wärtsilä Gas Solutions.
The plant produces biomethane from organic waste, including food waste, and from the municipality's wastewater treatment residue.
The Wärtsilä equipment is scheduled to be delivered in December 2024, and the new plant is expected to become operational in the first half of 2025.
