  • Method of utilizing energy of high pressure condensate
    Patent number: 4555310
    Abstract: A method of utilizing the energy of a high pressure condensate stream including passing steam at an elevated pressure in indirect heat exchange with a material to be heated, collecting a condensate product condensed from the steam of the heat exchange step at an elevated pressure, passing the condensate directly to a steam stripping step at essentially the same pressure at which the condensate was collected and reducing the pressure of the condensate while simultaneously contacting the condensate with a material to be stripped in the stripping step.
