Title:
METHOD AND DEVICE FOR RECOVERING CARBON DIOXIDE
Document Type and Number:
WIPO Patent Application WO/2017/159017
Kind Code:
A1
Abstract:
Provided is a carbon-dioxide recovering device including: a separating device SP that separates carbon dioxide from a gas by utilizing adsorption and desorption of carbon dioxide due to pressure changes with respect to an adsorbent, and that discharges a residual gas from which carbon dioxide has been removed; a drying device DR that has a moisture adsorbent for drying the gas to be supplied to the separating device; a regenerating system RG that supplies the residual gas discharged from the separating device to the drying device so as to serve as a regenerating gas for regenerating the moisture adsorbent in the drying device; and a supplement system SU that supplies a supplement gas to the residual gas from the outside in accordance with the flow volume of the residual gas discharged from the separating device so that the flow volume of the regenerating gas reaches a predetermined volume. The regenerating gas, heated by means of heat exchange between the gas and the regenerating gas, is supplied to the drying device.
