Title:
DEVICE OF RECOVERING CARBON DIOXIDE, COMBUSTION SYSTEM, POWER GENERATION SYSTEM, AND METHOD OF RECOVERING CARBON DIOXIDE
Document Type and Number:
Japanese Patent JP2023033659
Kind Code:
A
Abstract:
To decrease energy consumption for recovering carbon dioxide.SOLUTION: There is provided a device of recovering carbon dioxide, comprising: a separation treatment unit separating carbon dioxide contained in raw material gas from the raw material gas by a membrane that allows carbon dioxide to permeate therethrough; a suction unit that sucks treated gas containing carbon dioxide separated from the raw material gas; a cooling unit disposed upstream of the suction unit to cool the treated gas using a coolant; a gasification unit that gasifies liquified gas using a coolant; and a circulation unit circulating the coolant between the cooling unit and the gasification unit so that the temperature of the coolant repeatedly rises by cooling the treated gas and falls by gasifying the liquified gas.SELECTED DRAWING: Figure 1
