An improved method for removing sulfur oxides from a hot gas by introducing the gas into a first compartment of a spray drying reactor chamber for settleable particulate removal, by then directing the gas to a second compartment of the reactor chamber wherein the gas is contacted with an atomized alkali slurry for sulfur oxide removal by formation of a dry mixture of sulfite and sulfate compounds, by removing a portion of the dry mixture from the gas in the second compartment and by passing the gas from the second compartment to a dry particle collection zone for removal of substantially all of the remaining gas entrained dry mixture.
