Title: CARBON DIOXIDE RECOVERY METHOD AND RECOVERY APPARATUS
Abstract:
The carbon dioxide recovery apparatus according to the present invention has a drying device DR having a moisture absorbent for drying a gas, and a separation device SP for separating carbon dioxide from the gas dried by the drying device and discharging a residual gas from which the carbon dioxide is separated. The recovery apparatus furthermore has an introduction part ID for introducing a regeneration gas from outside for regenerating the moisture absorbent, a regeneration system RG capable of supplying one of the regeneration gas introduced from the introduction part and the residual gas discharged from the separation device to the drying device, and a switching mechanism for switching supplying by the regeneration system between the regeneration gas and the residual gas in response to regeneration of the moisture absorbent.
