- a first chamber that includes;
a gas input;
a first liquid spray array; and
a second liquid spray array;
the first liquid spray array and the second liquid spray array being located at different locations within the chamber;
a second chamber including an oxidizing chamber;
a first source of ammonia bearing liquid having a conduit to the first liquid spray array; and
a second source of ammonia bearing liquid having a conduit to the second liquid spray array;
wherein the first source and the second source are configured so that the first source produces ammonia bearing liquid that has a different sulfur absorbing capacity than that produced by the second source; and
