| Abstract | Disclosed is a method of removing carbon dioxide from a process gas, the method comprising: contacting an ammoni ated Solution with the process gas in an absorption arrange ment 101, the ammoniated solution capturing at least a part of the carbon dioxide of the process gas, wherein the molar ratio, R, of ammonia to carbon dioxide in the ammoniated Solution is controlled such that substantially no precipitation of solids occurs within the absorption arrangement 101; allowing ammoniated solution including captured carbon dioxide to exit the absorptionarrangement 101; cooling the ammoniated Solution that has exited the absorption arrangement, wherein at least a part of the captured carbon dioxide is precipitated as Solid salt, separating at least a part of the precipitated Salt from the ammoniated solution; heating the ammoniated solu tion from which the at least a part of the precipitated salt has been separated. Such that Substantially no Solids are present in the heated ammoniated solution; and allowing the heated ammoniated solution to re-enter the absorption arrangement 101. Disclosed is also a system for removal of carbon dioxide from a process gas. |
