ABSTRACT:
A process for the agglomeration of flue gas desulfurization dust is disclosed comprising the steps of introducing flue gas desulfurization dust as feed material into a conventional, high-intensity mixing device and admixing with water to form spheroidal agglomerates ranging in size from a Tyler number of about 40 mesh to about 1/2 inches in size. The agglomerates are either dried to ambient temperature, or by dusting them with a portion of the dry feed material, and recovered. The process can effectively agglomerate any calcium- and sulfur-containing flue gas desulfurization dust by adjusting the amount of water added and providing for the proper amount of mixing energy and duration. The mixing device can be selected from any one of a group of conventional, high-intensity mixers consisting of, but not limited to, a pin mixer, paddle mixer, plow mixer, pan pelletizer and disc pelletizer. An agglomerate produced in accordance with the present invention is a free-flowing, non-dusting, non-hygroscopic product of desirable size having application as a soil additive which can be spread easily in agricultural type spreaders.
