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 1):
A method of ammonia-based oxidative desulfurization comprising:\n directing a current of sulfur dioxide containing gas through a vessel; mixing, in an ammonia-mixing chamber, a liquid and an ammonia source to produce a first ammonia-containing liquid that has a first pH; contacting, in an oxidation chamber, an oxygen-containing gas with a second ammonia-containing liquid that has a second pH that is lower than the first pH; spraying the first ammonia-containing liquid in the vessel against the current; after the spraying the first ammonia-containing liquid, recirculating the first ammonia-containing liquid to the ammonia-mixing chamber; spraying the second ammonia-containing liquid in the vessel against the current; after the spraying the second ammonia-containing liquid, recirculating the second ammonia-containing liquid to the oxidation chamber; and transferring material between the oxidation chamber and the ammonia-mixing chamber through a balance hole defined in a partition between the oxidation chamber and the ammonia-mixing chamber.
