The biogas Upgrading Unit through amines, designed by us, is located downstream of the membrane unit and is suitable for implementation also on farms as it has a low level of danger, with a practically zero environmental impact, as well as being easily manageable by unskilled operators.
Our amino process, able to extract practically the entire CO2 content from biogas (passes from 40% to less than 50 parts per million), also captures H2S, so that sweetened biomethane is not a corrosive gas but, on the contrary, it is possible to use ordinary carbon steel or all at most Aisi 304 for its technological installations.
Downstream of our upgrading process, which we reaffirms, it includes the necessary membranes and filters inside, it is possible to install any type of plant to obtain liquid biomethane or it is possible to put it into the network, fill it up in cylinders or, more simply, use it directly in the breeding.
The amines can be used for a long time and, finally, regenerated using an external service.
