Wärtsilä combines gas units to create one-stop biogas solutions service

In Sweden, Wärtsilä Puregas Solutions has merged with Wärtsilä’s biogas liquefaction team, a unit with expert capabilities in liquefying upgraded biogas for end-customer use. Wärtsilä Biogas Solutions will now be better able to offer customers a one-stop-shop service for advanced biofuel production.

Wärtsilä has earlier provided the turnkey installation for the world’s largest bioLNG facility located in Skogn, Norway and will, by the end of the year, deliver two more bio-LNG plants to customers in Scandinavia. Interest from both the European and North American markets is high, and Wärtsilä anticipates continued strong growth in this sector.

Wärtsilä’s biogas upgrading plants utilise its in-house Puregas CA technology, a process that recovers more than 99.9 percent of the biomethane present in raw biogas. The process separates the CO2 from the biogas through chemical adsorption. The process is highly tolerant of variations in the raw gas composition resulting from changes in the feedstock.
