The worlds largest bioLNG plant, featuring Puregas Solutions technology, has been officially opened by Norwegian Prime Minister, Erna Solberg. The biogas upgrading and liquefaction plant was installed at the Norske Skog Skogn paper mill. The plant will convert the cleaned biogas from fishery waste and residual paper mill slurry into liquid bioLNG fuel.
The plant, which will upgrade up to 3,000Nm3/h of raw biogas to Renewable Natural Gas (RNG), will be part of the largest biogas liquefaction plant in the Nordic Countries producing fuel for public transport vehicles. Construction was managed by the Scandinavian Biogas subsidiary Biokraft AS.
“We are extremely proud to be involved in this project. Our unique CApure process is ideally suited to Liquefaction Projects as we are able to reduce the CO2 content of the biomethane to below 50ppm, making liquefaction possible”, said Sven Fischer, Key Account Manager bioLNG, Puregas Solutions.
The CApure process recovers over 99.9% of the biomethane present in the raw biogas by separating the CO2 from the biogas through a process of chemical adsorption. The selective organic solvents used in this process are so efficient that the product gas can contain over 99% biomethane. The biomethane can be directly injected in to the gas grid, compressed to produce bioCNG or liquefied for bioLNG. It’s also possible to capture the CO2 from the plant and use this for commercial purposes.
