Claim 0:
1. A biogas collection and purification system, the system aggregating biogas from a plurality of remote sources and treating the biogas to produce biomethane, the system comprising:
a network of conduits configured to convey biogas from the plurality of remote sources of the biogas based on a detected availability of biogas at each of the respective remote sources;
a biogas compressor located at each of the plurality of remote sources, each of the biogas compressors controlledly supplying biogas to a collection header of the network of conduits;
a central processing facility receiving the biogas conveyed in the network of conduits from the plurality of remote sources of biogas via a feed biogas compressor of the central processing facility, the central processing facility processing the biogas into biomethane, the central processing facility having:
a biogas hydrogen sulfide removal stage;
an activated carbon scrubber;
a carbon dioxide removal stage;
a cooler positioned between the activated carbon scrubber and the carbon dioxide removal state, wherein the cooler is configured to lower a temperature of the biogas, and
a processed gas compressor positioned downstream from the carbon dioxide removal stage and configured to compress the biomethane;

wherein a central controller receives input data, including data about gas availability at the remote sources, and the central controller controls the biogas compressors at each remote facility, the feed biogas compressor of the treatment facility, and the processed gas compressor.
