The PowerDigest has been developed for feedstock with low dry matter. It is ideally suited for large cattle farms, as well as for the agro-industrial sector.
The PowerDigest consists of a concrete or steel tank with a gasholder on top to guarantee space saving and a compact design. Due to our long-shaft mixers, a good homogenization of the feedstock can be achieved, fostering the degradation of the biomass. Moreover, the PowerDigest includes an improved biological desulphurization solution which decreases significantly the H2S content, minimizing the amount of active carbon needed for downstream gas cleaning. Furthermore, its gravitational overflow helps to reduce electrical consumption.
Due to its high flexibility, it is possible to combine as many PowerDigest as needed to treat all the available feedstock. In addition, this plant can work with a CHP, a gas upgrading unit, or a boiler as downstream processing equipment without any complicated interfaces or gas losses. In our plants we reach average full-load hours of more than 94%. The equipment of the plant can be either placed in an operational building or be delivered in practical 20-foot containers to be just placed on site – a time saving option!
High reliability and easy maintenance
Only reliable plant components from reputable suppliers have been chosen for this plant. Special focus lies on the agitation technology, which is very efficient due to the use of strategically placed long-shaft mixers. The mixer engines are placed outside of the digester and are directly accessible, making maintenance of the system effortless.
