<p>A carbon dioxide capture and sequestration process includes a first stage of scrubbing a gas stream containing carbon dioxide with a solution comprising normal ammonium carbonate that is able to absorb the carbon dioxide whereby the carbon dioxide reacts with the ammonium carbonate to produce a solution comprising ammonium bicarbonate. In a second stage, a reactive slurry consisting of a metal silicate rock together with the ammonium bicarbonate solution is passed through a reactor that is controlled so as to promote the reaction between the bicarbonate and the silicate rock to produce metal carbonate and silica.</p> |
