Abstract

The invention relates to a method and to a system for gas scrubbing of aerosol-containing process gases using an amine-containing solvent as scrubbing agent, which is brought into contact with the process gas in an absorber column (9) and which is regenerated in a desorber column (13) and after cooling is delivered to the absorber column (9) again. The water vapor concentration of the process gas which is not saturated with water vapor is increased with water before the gas scrubbing in the absorber column (9), preferably to a degree of saturation of >0.8, such that water is condensed out of the gas phase on aerosol particles contained in the process gas, and in a following method step the aerosol particles which have grown in size are precipitated out of the process gas before the gas scrubbing.
