An apparatus for cleaning gas, the apparatus comprising:
- a chamber that includes:
- a gas input;
- a first liquid spray array;
- a second liquid spray array;
- and
- a demister;
- the first liquid spray array and the second liquid spray array being located at different locations within the chamber;
- a first source of ammonia bearing liquid having a conduit to the first liquid spray array;
- 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.
