摘要: The invention provides a method for absorbing carbon dioxide from a gas stream containing carbon dioxide and dioxygen (O2), the method comprising contacting the gas stream with a liquid absorbent comprising i) at least one amine of Formula (I), and ii) at least one aliphatic amine. The compound of Formula (I) is selectively degraded by the O2 to form a degradation product comprising at least one imine of Formula (II). In the amine of Formula (I) and the imine of Formula (II), each Ar is independently an aromatic group and each R is independently selected from hydrogen, an organyl group and NH2.

摘要: An absorption column 1 for separating CO
2 and a second acid gas from a gas stream, the column comprising a first and second section (4, 5) for the absorption of CO
2 and the second acid gas; a solvent inlet in the second section for the addition of liquid stream 3 including an absorbent liquid for CO
2 and the second acid gas; a gas inlet (21) in the first section for the addition of a gas stream (2) containing CO
2 and the second acid gas; a gas outlet (15) in the second section of the column; a first solvent outlet (22) for the removal of at least a portion of the solvent (6) from the second section of the column and a second solvent outlet (23) for solvent stream (11) from the first section of the column; and a liquid flow distributor arrangement (8) to allow a portion of the solvent to flow from the second section of the column to the first section. A method of operating the apparatus and method of solvent extraction is also disclosed.摘要翻译: 用于从气流中分离CO 2和第二酸性气体的吸收塔1,该塔包括用于吸收CO 2和第二酸性气体的第一和第二部分(4,5); 用于添加包括用于CO 2的吸收液体和第二酸性气体的液体流3的第二部分中的溶剂入口; 第一部分中的用于添加含有CO 2和第二酸性气体的气流(2)的气体入口(21) 柱的第二部分中的气体出口(15); 用于从塔的第二部分除去至少一部分溶剂(6)的第一溶剂出口(22)和用于来自塔的第一部分的溶剂流(11)的第二溶剂出口(23); 以及液体流量分配器装置(8),以允许溶剂的一部分从塔的第二部分流动到第一部分。 还公开了一种操作溶剂萃取装置和方法的方法。
