Wärtsilä Gas Solutions launches tech to purify and liquefy CO2 from biogas upgrading
Traditional biogas upgrading plants have been based on the ‘catch and release’ of the carbon dioxide. Instead of releasing the carbon dioxide to atmosphere, Puregas BC utilises the best available technologies for purifying and liquefying carbon dioxide. The solution turns biogas, an already circular, zero carbon footprint fuel, into a carbon negative solution. With Wärtsilä Gas Solutions Puregas CA biogas upgrading system, the Puregas BC solution eliminates the already minimal (less than 0.1%) methane emissions, as any methane slip can be routed back to the upgrader.
In addition to the environmental benefits, the solution also offers a new commercially profitable revenue stream for the plant owner, as the captured carbon dioxide is purified to food and beverage grade, and/or storage grade. Upcoming regulations for e-fuels production is requiring bio CO2 as feedstock, making the Puregas BC solution an ideal fit.
