Abstract
A system for removal of carbon dioxide from a process gas includes an absorption arrangement arranged to allow contact between the process gas and an ammoniated solution within the absorption arrangement such that at least a part of the carbon dioxide of the process gas is captured by the ammoniated solution. The absorption arrangement is arranged to, with regard to the ammoniated solution, only accommodate ammoniated solution without solids. A first heat exchanger is arranged to cool the ammoniated solution including captured carbon dioxide after it has exited the absorption arrangement. A separator is arranged to remove at least a part of any solids in the cooled ammoniated solution. A second heat exchanger is arranged to heat the ammoniated solution after it has exited the separator and returned to the absorption arrangement.
