A system for capturing C02 from a flue gas stream comprises: - a C02 absorber (18) comprising first and second absorption stages (54, 56), - first contacting means (58, 60) for contacting, in the first stage (54), the flue gas stream (FG) with a mixture of C02-lean ammoniated solution and recirculated C02- enriched ammoniated solution, - second contacting means (62, 64) for contacting, in the second stage (56), partly cleaned flue gas stream with the recirculated C02-enriched solution, - a device (66) for collecting the mixture of C02-lean solution and recirculated C02- enriched solution, - a pipe (20) for passing a first portion of the collected C02-enriched solution for regeneration, - a C02-lean solution pipe (34) for passing the C02-lean solution from regeneration to the first stage (54), and - a recirculation pipe (74) for passing a second portion of the collected C02-enriched solution to the second stage (56). |
