Availability guarantees of individual component parts of the biogas plant will not provide expected long term returns alone, particularly if the entire facility is not integrated to work as one. A biogas plant is the sum of several critical components, each interdependent, and the performance of the plant is driven by how well those components interface.
Wartsila Biogas Solutions work with our customers to ensure our offering optimises performance across the entire biogas plant.
The Puregas CA process includes a unique heat recovery option. Energy is recovered from the biogas upgrading process and fed into the anaerobic digestion by pre-heating the substrate. Compared with other biogas upgrading techniques, CApure heat recovery reduces the need for electric power, which can reduce energy cost by up to 50%.
Additional value can be derived from the pure CO2 stream produced as is it removed from the biogas. This CO2 can be captured and used for propagation in glass houses, as a cooling agent or in general industrial applications.
