The present invention relates to a C02 removal system (1) for removing C02 from a C02 rich gas stream, said system comprising: a C02 capture arrangement (2) configured to receive the C02 rich gas stream and contacting the gas stream with an ammoniated solution stream to produce a C02 lean gas stream; and a chiller arrangement ( 3 ) comprising: a first heat exchanger ( 7 ) configured to receive the C02 rich gas stream and chill the gas stream by means of heat exchanging with circulating cooling medium, and a second heat exchanger ( 8 ) configured to receive circulating cooling medium, and chill the circulating cooling medium by means of heat exchanging with the C02 lean gas stream; wherein parts of the first ( 7 ) and second ( 8 ) heat exchangers are comprised in first and second cooling medium loops for the circulating cooling medium, wherein the second cooling medium loop is configured for a lower flow rate than the first cooling medium loop. |
