  • Cryogenic air separation process with excess turbine refrigeration
    Publication number: 20070095100
    Abstract: A process for carrying out cryogenic air separation wherein liquid oxygen is pressurized and vaporized against condensing feed air to produce oxygen gas product wherein excess plant refrigeration is generated such that the aggregate warm end temperature difference of the process exceeds the minimum internal temperature difference of the primary heat exchanger by at least 2K.
    Type: Application
