<p>PURPOSE:To remove the water content and prevent the water content from storing in an adsorbent by cooling raw material-mixed gas, and then passing a rotating continuous regenerating dehumidifiaction device, and using non- adsorption gas exhausted at the time of pressure vibration type gas adsorption separation as the gas for regeneration of said dehumidification device. CONSTITUTION:When carbon dioxide gas is recovered out of raw material-mixed gas having water content by the pressure vibration type gas for the adsorption separation process, the water content in the raw material mixed gas is removed. At this time, non-adsorption gas heated by a heat exchanger 2 is introduced into a regeneration zone of a rotating continuous regeneration humidification device 6 to be used for removing the water content adsorbed to a meter of said dehumidification device 6. Also, dust in the exhaust gas is removed in a water washing column 3 and cured therein. After that, cooling dehumidification is carried out in a cooling device 7 and a cooling device 8 using chiller water, and the exhaust gas is introduced to a dehumidification zone of the rotating continuous regeneration dehumidification device 6, and carbon dioxide gas is separated and recovered efficiently. Thus, the storing of water content in the adsorbent is not generated.</p> |
