Absorbedor secador de pulverizacion para eliminar contaminantes gaseosos de un gas de proceso caliente, reduciendo el riesgo de formacion de grandes agregados, que comprende una camara secadora y un numero par de dispersadores, por lo menos cuatro, en el techo de esta, para dispersar el gas de proceso alrededor del atomizadores respectivos, estando equidistantes de la periferia; metodo asociado

Absorbedor secador de pulverización para eliminar contaminantes gaseosos de un gas de proceso caliente, que comprende una cámara secadora y al menos dos dispersadores en el techo de ésta, para dispersar el gas de proceso alrededor del atomizadores respectivos, estando equidistantes de la periferia; método. A spray dryer absorber (8) is operative for removing gaseous pollutants from a hot process gas and comprises a plurality of dispersers (14, 16, 18, 20). Each such disperser (14, 16, 18, 20) is operative for dispersing a portion of the hot process gas around a respective atomizer (24), and for providing the respective portion of the hot process gas with a rotary movement around the atomizer (24). The spray dryer absorber (8) comprises an even number of dispersers (14, 16, 18, 20), such even number being at least 4. Each disperser (14) is operative for providing the hot process gas passing through that specific disperser (14) with a rotary movement in a direction (FC), which is opposite to the direction (FCC) of the rotary movement of the respective portions of the hot process gas dispersed by the two dispersers (16, 20) being located closest to that specific disperser (14).
