Zusammenfassung:	A system for removing carbon dioxide from a flow of gas having carbon dioxide therein is featured. The system includes a first venturi eductor and first reactor which receive the flow of gas having carbon dioxide therein and a flow of a first alkaline solution at a first predetermined pH range. The first venturi eductor and reactor mix and provide reaction time for the flow of gas having carbon dioxide therein and the flow of the first alkaline solution to induce a reaction of the carbon dioxide with the first alkaline solution to form a solution having metal bicarbonate therein. A second venturi eductor and reactor mix the flow of the partially treated gas with the flow of the second alkaline solution and provide reaction time to react a majority of the remaining carbon dioxide with the second alkaline solution to form a solution having metal carbonate therein.
