Abstract
In flue gas desulfurization, sorbent promoters are recovered by mixing collected particulates with water to form a slurry. The slurry is dewatered and wet solids are disposed. The recovered material contains water soluble desulfurization promoters and is reinjected in a flue gas desulfurization humidification system. The recycle allows recovery of water soluble promoters and reduces consumption. In addition, for promoters having undesirable disposal characteristics, the system improves the disposal characteristics of the waste solids.
