Abstract:
Apparatus and methods for controlling aerosol production during absorption in ammonia desulfurization, by removing sulfur dioxide in flue gas with an absorption circulation liquid containing ammonium sulfite, so as to control the aerosol production during absorption in ammonia desulfurization. Efficient desulfurization and dust removal may be achieved by staged solution composition control and reaction condition control. At the same time ammonia escape and aerosol production during absorption may be controlled. The flue gas may be subjected to preliminary temperature lowering and purification, and may be allowed to contact with an absorption circulation liquid and a fine particle washing circulation liquid sequentially. Levels of solution compositions and reaction temperatures may be controlled.

Claim (Index 141):
The method of  claim 134  wherein:\n the removing comprises spraying fine particle washing circulation liquid at two stages; and, \n at a stage of the stages, the spraying comprises spraying fine particle washing circulation liquid having:\n 0.1%-1% ammonium sulfite; and \n 5%-38% ammonium sulfate.
