摘要
A system (1) for removing carbon dioxide (CO2) from a gas stream by bringing the gas stream into contact with a circulating ammoniated solution stream such that CO2 is absorbed in said ammoniated solution, characterized in that the system comprises a membrane purifier (17), said membrane purifier having a first compartment (18) and a second compartment (19), wherein said first and second compartment are separated by a semipermeable membrane (20), a method for removing carbon dioxide (CO2) from a gas stream by bringing the gas stream into contact with a circulating ammoniated solution stream such that CO2 is absorbed in said ammoniated solution, said method comprising the step of separating trace components from a circulating solution using a semipermeable membrane, and the use of a membrane purifier having a first and a second compartment, wherein said first and a second compartments are separated by a semipermeable membrane, for reducing the trace component and/or water content of a circulating solution stream in a method or system for removing carbon dioxide (CO2) using a circulating ammoniated solution.
