Finnish shipping technology group Wartsila has merged its Puregas Solutions and biogas liquefaction teams to form a new Biogas Solutions unit that will offer its customers a ‘one-stop-shop service’ for advanced biofuel production.
Wärtsilä Biogas Solutions, a unit with expert capabilities in liquefying upgraded biogas for end-customer use, offers products for biogas upgrading to biomethane, and the liquefaction of biomethane into bioLNG.
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.
Wärtsilä’s biogas upgrading plants utilize 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.
