An increasing number of biomethane producers, whether they bring gas-to-grid or produce bioCNG or bioLNG, want to have effective carbon dioxide (CO²) management to maximise yield and minimise environmental impact. Pentair has launched a compact enclosed skid CO² recovery system that can be connected to any existing biogas upgrading plant.

Biogas produced through anaerobic digestion consists of roughly 55 per cent methane and 45 per cent CO². With conventional biogas upgrading techniques, the CO² by-product and with it a considerable amount of methane is expelled into the air and is lost. This means not only economic loss but also environmental damage.

Pentair CO² recovery systems allow plant operators to recover the CO² from the biogas stream, which minimises the plant’s overall CO² footprint, and allows for a wider choice in feedstock. The recovered CO² can be used in a variety of applications including as gaseous fertiliser in greenhouses or for the production of dry ice.

As the produced CO² complies with EIGA (European Industrial Gases Association) specifications, an additional option can be to sell the liquefied CO² to a third party.

pentair-2Pentair partners with a major industrial gas company and can assist plant operators in getting into contact. Some figures: For a CO² recovery system that is currently being implemented after an existing 2,000 Nm³ upgrader in Southern England, an estimated amount of 34 tons of liquefied CO² per day is planned to be sold to a gas company, which results in a significant additional revenue stream for the plant operator.

  • Eliminating any methane slip

Pentair’s technology even goes one step further. During the CO² recovery process, all impurities – including the ‘methane slip‘ that occurs with conventional biogas upgrading technologies are removed from the CO² and sent back to the biogas upgrading system.This results in significantly higher methane yield – for the above-mentioned project, an estimated 87,600 cubic metres per year which completely eliminates any methane slip. The portion of environmentally-harmful greenhouse gases released to the atmosphere is reduced to almost zero, which makes this technology a future-proof investment.

  • Stand-alone unit in an enclosed housing

With capacities of up to 1,000kg/h, the compact enclosed skid CO² recovery system for biogas upgraders is delivered as a stand-alone unit. Built according to customer specifications, yet standardised to a high degree, delivery and start-up of the system can be accomplished in just 16 weeks.

Through comprehensive lifecycle management including a global network of service engineers and an in-house CO² analysis service, Pentair ensures that the installation operates at optimal performance.

  • 25+ references in biogas upgrading

By partnering with Pentair plant operators can be assured of receiving the best solution for their specific biogas upgrading project. Pentair provides a wide range of solutions for biogas upgrading and CO² recovery – from standard biogas upgrading systems with membrane technology at its heart to custom-made solutions combining biogas upgrading and CO² recovery to stand-alone CO² recovery units.Since entering the biogas upgrading market in 2010, Pentair has experienced amazing success with its innovative technology.

To date, 25+ biogas upgrading projects have been realised in the Netherlands, Germany, France and the UK. Further projects are set to be completed in South Africa and the Philippines this year.
