Abstract

A method for eliminating or substantially reducing emission of amines (amineslip) and alkaline degradation products to the atmosphere from a plant for COcapture from a flue gas, where the COis captured by counter-current flow to an absorbent in an absorption zone, the absorbent comprising an aqueous solution of one or more amine(s), to give a COlean flue gas that is released into the surroundings, and a COrich absorbent that is regenerated in a regeneration column to give a COrich gas that is treated further, and regenerated absorbent that is recycled to the absorption zone, wherein the COlean flue gas is washed with an acidic aqueous solution to remove or substantially reduce the amount of amine(s) and alkaline degradation products thereof in the gas, is described.
