Potential Production and Marketing of FGD Byproduct Sulfur and Sulfuric Acid in the U.S. (1983Projection).

摘要

The report updates to 1983 a 1978-base,computerized marketing evaluation of sulfur and H2SO4as flue gas desulfurization (FGD) byproducts from U.S. coal-burning power plants. Least-costs of compliance were calculated using comparisons of clean fuel with 50cents and 70cents/million Btu premiums,limestone scrubbing,and scrubbing systems with byproduct sulfur and H2SO4production. Market potential of sales to sulfur-burning H2SO4plants was also determined. At the 50cent premium, H2SO4production was the least-cost method at five plants,four of which had combined sales of 800,000tons/yr. At the 70cent premium, H2SO4production was the least-cost method at 26plants, 7of which had sales totaling 1.2million tons. New boilers coming online by 1983accounted for 60% of the sales. Market potential was relatively insensitive to sulfur price. Sulfur production was not selected at any plant,but reduction of total FGD costs by 3-25% would make it competitive with sulfur delivered from Port Sulphur at 16plants with a total production of 266,000tons. Results indicate the need of a longer time projection and continued updating of the model data bases.
