    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.
