<p>A spray dryer absorber (308) is operative for removing gaseous pollutants from a hot process gas and comprises at least two dispersers (314, 316, 318, 320, 321 ). Each such disperser 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). At least one specific disperser (314) is operative for providing the hot process gas passing through that specific disperser (314) with a rotary movement in a direction (FC), which is opposite to the direction (FCC) of the rotary movement of the respective portion of the hot process gas dispersed by at least one other disperser (316) being located closest to that specific disperser (314).</p> |
