Title:
CARBON DIOXIDE SEPARATION AND RECOVERY SYSTEM, AND CARBON DIOXIDE SEPARATION AND RECOVERY METHOD
Document Type and Number:
WIPO Patent Application WO/2024/058048
Kind Code:
A1
Abstract:
This carbon dioxide separation and recovery system comprises: an adsorption module in which a first liquid phase region and a first gas phase region are divided by a plurality of first hollow fiber membranes; a desorption module in which a second liquid phase region and a second gas phase region are divided by a plurality of second hollow fiber membranes; a liquid supply device that communicates with the first liquid phase region; a target gas supply device that communicates with the first gas phase region; a liquid communication path that is connected to the adsorption module and the desorption module and that communicates between first liquid phase region and the second liquid phase region; and a gas recovery path that communicates with the second gas phase region. Each of the plurality of first hollow fiber membranes and each of the plurality of second hollow fiber membranes comprises a dense layer that is not porous, and a porous layer positioned on the inside of the dense layer that is porous.
