Title:
CARBON DIOXIDE RECOVERY SYSTEM AND CARBON DIOXIDE RECOVERY METHOD
Document Type and Number:
WIPO Patent Application WO/2024/090105
Kind Code:
A1
Abstract:
This carbon dioxide recovery system comprises: a carbon dioxide extraction device that bonds carbon dioxide included in exhaust gas discharged from a combustion device to an absorption liquid or an adsorption material; a separation device that separates a carbon dioxide gas from the absorption liquid or the adsorption material, the separation device including a heater that heats the absorption liquid or the adsorption material through heat exchange with a heat medium; and a liquefaction device that liquefies the carbon dioxide gas. The liquefaction device includes: a compressor that compresses the carbon dioxide gas; a heat exchanger that performs heat exchange between the heat medium introduced into the heater and the compressed carbon dioxide gas; a cooler that performs heat exchange between the compressed carbon dioxide gas and a first cooling/heating medium and cools the carbon dioxide gas; and a liquefier that performs heat exchange between the carbon dioxide gas, which has passed through the heat exchanger and the cooler, and a second cooling/heating medium and liquefies the carbon dioxide gas.
