27. A method of removing CO2 from a flue gas stream containing carbon dioxide, the method comprising the steps of:
-
contacting a first ionic solution flow with a flue gas stream to remove a first portion of CO2 from the flue gas stream; contacting a second ionic solution flow with the flue gas stream to remove a second portion of CO2 from the flue gas stream; contacting a third ionic solution flow with a flue gas stream to remove a third portion of CO2 from the flue gas stream; and cooling the third ionic solution flow so as to minimize ammonia slip from the ionic solution. - View Dependent Claims (28, 29, 30, 31, 32, 33)
