  • Systems and Methods for Utilizing Boil-Off Gas for Supplemental Cooling in Natural Gas Liquefaction Plants
    Publication number: 20230258400
    Abstract: Systems and methods for using a multi-stage compressor to increase the temperature and pressure of BOG sent to a heat exchanger for cooling a separate liquid refrigerant. The subsequent stage(s) of the multi-stage compressor further compress the BOG, which is then recycled to a liquefaction unit or used as fuel gas for one or more turbines.
