ABSTRACT:
Wet air preferably from a liquid ring pump is dehumidified by the use of a desiccant liquid absorber. The heat released by condensation of water vapor in the absorption liquid will be taken up by the air. The air is further heated by water vapor produced by regenerating the absorption liquid. According to a preferred embodiment of the invention, the source of the wet air is a suction box in the forming section, couch roll or pick-up roll of a paper machine and the hot air is used as pocket ventilation air in the dryer section of the paper machine.
