Method for removing CO2 from coal-fired power plant flue gas using ammonia as the scrubbing solution, with a chemical additive for reducing NH3 losses, coupled with a membrane for concentrating the CO2 stream to the gas stripper
A method for removing and capturing carbon dioxide from a fluid stream includes the steps of exposing the fluid stream to an aqueous scrubbing solution that removes and holds carbon dioxide from the fluid stream, passing the aqueous scrubbing solution through a membrane in order to separate excess water from the scrubbing solution and increase the concentration of carbon dioxide in the scrubbing solution, heating the scrubbing solution having an increased concentration of carbon dioxide so as to release carbon dioxide gas and recycling the scrubbing solution. A carbon dioxide capture apparatus includes a carbon dioxide scrubber, a membrane downstream from the scrubber for separating water and concentrating carbon dioxide in a scrubbing solution and a stripper vessel.
