Abstract:
Apparatus and methods for desulfurization of a sulfur-oxide containing gas by treatment with ammonia containing liquids. The apparatus and methods may utilize two distinct circuits of two different ammonia containing liquids which are applied in two distinct chambers. The gas may be cooled prior to entry into the circuits. There may be fluid communication between the two circulation circuits.

Claim (Index 45):
An apparatus for removing sulfur from a gas stream, the apparatus comprising:\n a first sprayer circuit configured to spray a first liquid countercurrent to the gas stream, the first sprayer circuit including:\n a first sprayer assembly; and \n an ammonia-mixing chamber including:\n an ammonia input port; \n a first-liquid return port; \n a first-liquid supply port configured to supply first liquid to the first sprayer assembly; and \n a surface that defines a balance hole that places material from inside the ammonia-mixing chamber in diffusive communication with material from outside of the ammonia-mixing chamber; and \n \n a second sprayer circuit configured to spray a second liquid countercurrent to the gas stream, the second sprayer circuit including:\n a second sprayer assembly downstream, relative to the gas stream, from the first sprayer assembly; and \n an oxidation chamber having:\n a gas input configured for contacting an oxygen-containing gas with an ammonia-containing liquid in the oxidation chamber; \n a second-liquid return port configured to receive second liquid after the second liquid is sprayed; and \n a second-liquid supply port configured to supply second liquid to the second sprayer assembly.
