Abstract
A methane gas mitigation system includes an engine comprising a fuel intake configured to receive a gas fuel source and produce mechanical power based on the gas fuel source; a primary gas compressor mechanically driven by the engine and configured to compress a majority portion of field gas into compressed field gas, and vent a minority portion of the field gas as a vented field gas; a vented flow path configured to carry the vented field gas from the primary gas compressor; a secondary gas compressor arranged on the vented flow path and configured to compress the vented field gas to satisfy a gas pressure operating range of the engine; and an engine fuel rail coupled to an output of the secondary gas compressor and configured to provide the vented field gas, within the gas pressure operating range, to the fuel intake of the engine.
