Abstract
The invention provides a scrubbing column for cleaning gas streams laden with absorbent residues, for example with methanol, and also with solid particles, for example with fuel dust. The gas scrubbing is effected by means of a random packing disposed in the lower region of the scrubbing column and the gas scrubbing of the gas stream laden solely with absorbent residues but not with solid particles by means of a structured packing disposed in the upper region of the scrubbing column. The use of the scrubbing column according to the invention in the integrated plant system between a gasification plant and a plant for gas scrubbing which is operated by the Rectisol process, for example, offers particular advantages with regard to its industrial employability owing to the possible connections described, which bring synergies for efficient operation of the integrated plant system.
