Superior cost-effectiveness in flue gas desulfurization via high-volume, high value byproduct generation
Current worldwide advancements in application and commercial operation of ammonia-base flue gas desulfurization, (FGD), in electric utility service, motivated in part by significant revenues from ammonium sulfate output, are detailed. This new direction in FGD process selection and in the design of flue gas cleaning installations achieves major performance advancements herein reviewed. Attractive cost effectiveness, achieved in the face of substantial capital cost, is quantified. Favorable process economics, superior to that of all available alternatives for high-capacity, high-sulfur, powerplant service, is made possible through substantial value added in conversion of ammonia reagent consumed to agglomerated byproduct, principally ammonium sulfate. This low-nitrogen-content compound, the poor man's fertilizer of times past, is now in great and growing demand for use as sulfur blending stock in worldwide, commercial NPKS, (nitrogen/phosphorus/ potassium/sulfur), chemical fertilizer manufacture.
