Technology group - Wärtsilä 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 earlier by Wärtsilä and will bring the production of bioLNG from 20 to 45 tons per day.
VAC vacuum technology
The plant, located in Linköping, is owned by Tekniska Verken, a municipality-owned company and a pioneer in Sweden in biogas and bioLNG production. 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 district heating network.
Biomethane capacity expansion
We are complementing our existing upgrading and liquefaction plant, as well as continuing to contribute to the journey"
“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 to the journey towards our vision of becoming the world’s most resource-effective region,” said Anna Lövsén, CEO Svensk Biogas and Business Area Manager, Biogas, Tekniska Verken.
Anna Lövsén adds, "Our experience with the existing Wärtsilä plant has been positive, so we are looking forward to this extension project."
bioLNG
“Tekniska Verken is at the forefront of producing and promoting bioLNG in Sweden, and we are honoured to have been selected to further extend their existing plant,” commented Magnus Folkelid, Sales Manager Biogas, Wärtsilä Gas Solutions.
Magnus Folkelid adds, "Our corporate policy is to enable decarbonised operations wherever possible, and we look forward to delivering another high-performance process solution."
Circular business model
It is fully renewable and, depending upon the feedstock from which it is produced, can even be carbon-negative
The plant produces biomethane from organic waste, including food waste, and from the municipality’s wastewater treatment residue. The bioLNG is used as fuel for the transport sector and industry in Sweden.
At Tekniska Verken’s subsidiaries, Svensk Biogas bioLNG filling stations for heavy vehicles represent a circular business model. It is fully renewable and, depending upon the feedstock from which it is produced, can even be carbon-negative.
Wärtsilä scope features
The Wärtsilä scope features its Puregas biogas upgrading system Puregas CA, its Mixed Refrigerant (MR) biogas liquefaction solution, a 250 m3 storage tank, an export station, and a Boil Off Gas (BOG) module. The biogas upgrading system can also send biomethane to the local biogas grid.
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.
