Schmack Carbotech’s innovative Pressure Swing Adsorption (PSA) technology will be used in a development that will enable the Swedish capital to produce pure methane (biomethane) from more biogas.

This will increase the proportion of biomethane, it uses by 50%, this will provide biofuel for vehicles currently powered by natural gas. The biomethane produced will be a high purity gas leaving the PSA with a methane content in excess of 97 per cent.
Fed by organic waste and waste kitchen oil, the plant, which will be located in Sofielund, Huddinge, will produce biogas with an annual energy yield of nearly 100 million kilowatt hours. That's enough to supply approximately 5,000 vehicles clocking up an average of 20,000 km per year each.
Part of the Viessmann Group, Schmack Carbotech’s Pressure Swing Adsorption (PSA) principle distinguishes itself from other technologies because of its favourably low energy consumption, efficient heat extraction and high methane yield, as the company’s International Business Manager, Eberhart Wusterhaus Gomez, explains:
“This important new contract at Sofielund brings to bear all of our 30 years ‘experience in the development, engineering and manufacturing of turnkey gas upgrading plants.“As industry pioneers and market leaders in biogas purification, we are very keen to play our part in delivering a low energy yet high yield technology that in this case fits in perfectly with the Swedish government’s long-term thinking to become the world’s first completely oil-free economy”.
Setting new standards in biogas process efficiency, Sofielund’s new plant will be equipped with a CNG station, a Carbotech PSA plant, off-gas cleaning with high heat recovery system combined with a peak load boiler. The plant will also benefit from ultra-reliable VOC and Hydrogen Sulphide removal, making Carbotech’s robust technology ideal to produce biomethane from biogas, sewage gas and landfill gas for grid injection and CNG vehicle fuel. As well as being a specialist in upgrading biogas plants, the Viessmann Group is actively implementing complete biogas turnkey solutions worldwide. Installations include award-winning biological technology, with special wet fermentation (from Schmack Biogas) and batch-dry fermentation (BioFerm technology) now integral parts of more than 300 cogeneration and biomethane plants in Europe and beyond. This includes Europe’s largest dry-AD-from-organic-waste plant, located in Fife, Scotland.
The Viessmann Group is a leading international manufacturer of heating technology systems. Founded in 1917, the family company has around 11,400 employees with group sales of EUR 2.1 billion. Viessmann has an international presence with 27 production companies in 11 countries, sales companies and representations in 74 countries and 120 sales branches worldwide. 55 percent of sales are generated abroad.
