Abstract

Gas reacting apparatus and method are described for wet mass transfer of solute gases from a gas stream with a liquid or slurry reacting medium capable of chemisorption of solute gases in the gas stream. The apparatus comprises an elongated conduit means and plurality of dual-fluid spray means coaxially spaced in series within the conduit means and countercurrently or cocurrently directed to the gas stream for spraying the liquid or slurry reacting medium into the conduit means to form a plurality of spray contact zones of uniformly-distributed fine droplets, which may be in individual gas-liquid contact zones, wherein intimate contact of high interfacial surface area between the sprayed liquid or slurry and the gas stream is effected to remove solute gases from the gas stream. Such individual gas-liquid contact zones may be separated by demisters which agglomerate and remove liquid droplets from the gas stream before it passes to the next zone, with a demister also being provided at the outlet.
