Netherlands-based Pentair Haffmans, a wholly owned subsidiary of gas technology specialist for the food and beverage industry Pentair, has commissioned its first biogas to biomethane upgrading installation in Scandinavia. The plant is installed at the Norske Skog Saugbrug paper mill in Halden, Norway which was officially inaugurated April 3 by H.M King Harald of Norway.

– The new installations for biogas and nano-cellulose combine new technology and expertise into new, green businesses in synergy with current paper production. The new initiatives will deliver new revenue, jobs, and products at the same time as they are profitable. Saugbrugs is now almost a fully renewable factory both in terms of raw materials, energy, and finished goods. We are proud that we are well on the way to becoming a zero-emission company, said Kjell-Arve Kure, CEO of Norske Skog Saugbrugs AS in a statement.

Connected to the mill’s existing biochemical wastewater treatment plant (WWTP), the biogas plant uses the residual sludge. Pentair Haffmans supplied a multi-stage membrane-based biogas upgrading system with a raw gas capacity of 600 Nm3/h that is upgraded to approximately 490 Nm3/h of biomethane. The biomethane is compressed to compressed biomethane (Bio-CNG) and supplied to industrial gas distributor AGA where it is used to fuel a fleet of 70 buses and trucks in the region.

According to Pentair Haffmans, the compact structure biogas upgrading system was a major advantage for easy transport and installation. All components were preassembled on cubic steel skids and were converted into a weather-proof building on-site by attaching sidewalls and ceiling panels. The installation is accessible from all sides and even with the compact design, there is adequate space to make modifications, repairs or overhauls.

Since entering the biogas upgrading market in 2010, the company has over 40 biogas upgrading projects that have been completed or are under installation. These are located in the Netherlands, Germany, France, the UK, South Africa, the Philippines, and the USA whereas the Saugbrugs installation in Norway marks Pentair’s first project in Scandinavia.
