Zusammenfassung:	A process and apparatus for neutralizing hot acid gases is disclosed. Prior to neutralizing the gas, it is introduced into a zone, e.g., a cyclone to establish an upwardly, generally spiral gas stream. This gas motion permits removal from the gas of larger particles which concentrate at the cyclone wall by centifugal forces. The upwardly-moving gas stream which may or may not have a spiral motion is contacted with an upwardly-moving spray of a basic neutralizing liquid or slurry under conditions such that the spray droplets moderately overcome gravitational forces such that they experience a sufficiently long residence time in the cyclone to be evaporated to dryness. The product gas from the cyclone then can be treated further to remove small particles and salt product.
