Abstract

In the atomization absorption of a gas or gases in chemical reactions with an atomized, liquid solution and/or suspension of a reagent, in which the gas or gases possibly mixed with a neutral gas are fed through a reaction zone in which an atomization of the solution and/or the suspension occurs, the adsorption is performed in at last two successive stages each with its discrete reaction zone, in which atomization of the solution and/or suspension takes place. A more effective reaction is thereby obtained between gas and reagent, resulting in a reduced consumption of chemicals compared to absorption processes that are performed in only one stage. In a preferred embodiment of the apparatus, the absorption process takes place in two serially linked stages each with its reaction chamber 302, 303 with associated gas distributor 305, 315, and liquid atomizer 307, 317, the reaction chambers 302, 303 and their gas distributors 305, 315 and liquid atomizers 307, 317 associated with the two stages being arranged coaxially one above another in such a way that the bottom of the reaction chamber 302 belonging to the first upper stage forms the gas distributor 315 for and ceiling of the lower reaction chamber 303 belonging to the second stage. This method of construction significantly reduces the capital expenditure and space occupied by the apparatus. A branch line 322, which opens out in proximity to the gas distributor 315 for the second reaction chamber 303 can be brought from the gas distributor 305 for the first reaction chamber 302. A proportion of the untreated gas can thereby be led outside the first reaction chamber 302 to the second reaction chamber 303 with a view to controlling and optimizing the process parameters in the two reaction chambers. <IMAGE>
