Recovery of carbon dioxide from combustion exhaust gas

摘要

A method for recovering carbon dioxide gas present in combustion exhaust gas. More specifically, the present invention solves problems associated with the absorption of carbon dioxide from combustion exhaust gas using a monoethanolamine solution. First, with the provision of storage units for the monoethanolamine solution which has absorbed carbon dioxide and for the monoethanolamine solution which has been regenerated, variations in power demand at power generation facilities are utilized effectively. Also, provided is a method of recovering carbon dioxide wherein a monoethanolamine solution is made inflammable. Further, the optimization of exhaust gas from which carbon dioxide is recovered is achieved.
