Definitions

  • the droplet separators are cooled. If the product temperature is above the liquefaction temperature of these cooled surfaces, the outflowing steam can condense on the cold surfaces and, if so desired, can drip back into the product to be cooled as condensate.
  • the evacuation of the system is controlled so that no water vapor flows to the zeolite bed during this phase. According to the invention, the further flow of the water vapor is prevented by an air cushion in the zeolite bed.
  • the evacuation is controlled according to the invention in such a way that the pressure in the vacuum chamber decreases continuously, but the expansion of the gas cushion in the zeolite bed is retained. A boundary layer a few centimeters wide forms between the flowing water vapor and the blocking gas cushion.
