    • A method for removal of CO2 from a flue gas stream, comprising the steps of : a) contacting (101) a flue gas stream comprising CO2 (102) with a first absorption liquid comprising NH3 (103) such that the flue gas stream is depleted in CO2; b) contacting (106) the flue gas stream depleted in CO2 (105) of step a) with a second absorption liquid (107) such that NH3 from the flue gas stream is absorbed in said second absorption liquid to form a flue gas stream depleted in CO2 and NH3 (109); c) separating (110) NH3 from the second absorption liquid such that a gas stream comprising NH3 (114) is obtained; d) contacting (113) said gas stream comprising NH3 separated in step c) with a third absorption liquid (115) such that NH3 is absorbed in said third absorption liquid. A system for removal of CO2 from a flue gas stream, the system comprising: a CO2 absorption stage; an NH3 absorption stage; and a reabsorption stage.
    • 一种用于从烟道气流中去除CO 2的方法,包括以下步骤:a)使包含CO 2(102)的烟道气与包含NH 3(103)的第一吸收液体接触(101),使得废气流被耗尽 在二氧化碳 b)将耗尽步骤a)的CO 2(105)的烟气流与第二吸收液体(107)接触(106),使得来自烟道气流的NH 3被吸收在所述第二吸收液体中以形成废气流 在二氧化碳和NH3(109); c)从第二吸收液体分离(110)NH 3,从而得到包含NH 3(114)的气流; d)使包含在步骤c)中分离的NH 3的所述气流与第三吸收液体(115)接触,使得NH 3被吸收在所述第三吸收液体中。 一种用于从烟道气流中除去CO 2的系统,该系统包括:CO 2吸收阶段; NH3吸收阶段; 和再吸收阶段。
