Patent
CA 2090963
The invention relates to a process and a corresponding plant for the purification of gases, in particular flue gases, using a foam-forming reaction medium with which dirty gas is contacted in a reaction chamber, in which the foam is broken after the reaction between dirty gas and the reaction medium, the reaction medium recovered by the breaking and the settling sludge are separately collected and the purified gas is withdrawn. This invention is intended to enable the substances removed from the gases to be purified to be separated, when dirty gas having a temperature of about 60°C is purified, by carrying out the defoaming in the reaction chamber, collecting dense foam formed by the defoaming and reaction medium mixed with water and gases beneath the dense foam, removing the dense foam and surface sludge from the reaction chamber by suction and holding them for gravity separation, carrying out a layering of the substances to be separated in a settling phase, and successively separating the individual layers.
