  • Publication number: 20240085102
    Abstract: A system and method for recovering high-quality biomethane (RNG) from biogas sources is provided. The gas stream is compressed and liquids are separated from the gas stream at elevated pressure and reduced temperature. The compressing is performed using a plurality of compressors operating in parallel with common control set points. The system and method improve upon conventional practices and yield a biomethane product which meets strict gas pipeline quality specifications. Additionally, the system and method are an improvement to the overall methane recovery efficiency for biogas processing facilities.

  • Publication number: 20240085103
    Abstract: A system and method for recovering high-quality biomethane (RNG) from biogas sources are provided. The system and method improve upon conventional practices and yield a biomethane product which meets strict gas pipeline quality specifications. An online sample is captured of a gas stream in near real-time at a pressure swing adsorption vessel, and the online sample is analyzed to detect the presence of one or more targeted products such as CH4, CO2 or N2. The system and method are an improvement to the overall methane recovery efficiency for biogas processing facilities, specifically with regard to PSA control to prevent over or under saturation of the PSA media.
