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). |
