Title:
CARBON DIOXIDE CAPTURE PROCESS FOR COMBUSTION EXHAUST GAS LINKED TO DEHUMIDIFICATION PROCESS BY MEMBRANE DEHUMIDIFIER
Document Type and Number:
WIPO Patent Application WO/2023/277203
Kind Code:
A1
Abstract:
The present invention provides a carbon dioxide capture process for combustion exhaust gas to which a dehumidification process by a membrane dehumidifier is linked, the carbon dioxide capture process comprising: (I) a step for supplying combustion exhaust gas to a compressor; (II) a step for dehumidifying the compressed combustion exhaust gas by transferring same to a membrane dehumidifier; (III) a step for supplying the dehumidified combustion exhaust gas to a first stage separation membrane; (IV) a step for discharging carbon dioxide-removed gas from a first stage separation membrane exclusion unit and purging same to a discharge unit of the membrane dehumidifier; (V) a step for supplying, to a second stage separation membrane, the portion that passes through the first stage separation membrane; (VI) a step for concentrating carbon dioxide in the portion that passes through the second stage separation membrane; and (VII) a step for recirculating, as combustion exhaust gas, the portion that passes through the second stage separation membrane.
