Abstract
A biogas collection and purification system that includes a plurality of sources of biogas and a network of conduits configured to convey the biogas from the sources to a central processing facility for processing the biogas into methane. The central processing facility removes impurities to convert biogas to biomethane and may include an H2S removal stage; an activated carbon scrubber; a gas drier; and a carbon dioxide removal stage. The facility also has a biomethane gas compressor configured to deliver the biomethane for use in power plants, for CNG production. Ancillaries to the system include fuel cells for direct electricity generation from biogas/biomethane.
Claims20
A system for managing biogas production, the system comprising:
- a central processing facility configured to process biogas to form processed biogas;
- a network of biogas aggregation conduits fluidically coupling a plurality of remote biogas sources to the central processing facility, wherein the network of biogas aggregation conduits supply the biogas to the central processing facility;
- a controller configured to determine a predicted amount of biogas available at each of a plurality of remote biogas sources and biogas hold-up present in the network of biogas aggregation conduits;
- a processed biogas compressor configured to supply an amount of the processed biogas to one or more targets based on the predicted amount of biogas available.
