摘要

Pollution control legislation is requiring that sulfur dioxide (SO_2) emissions from coal fired power generation be reduced (to prevent acid rain). Abatement strategies such as Flue Gas Desulfurization (FGD) often result in the SO_2 being converted into gypsum (CaSO_4 centre dot 2H_2O), resulting in increased production of synthetic gypsum (gypsum from sources other than naturally occuring deposits). Often this gypsum is suitable for utilization, with utilization potential being a function of local economic factors and gypsum quality. Increasingly, power utilities are concluding that the production of wallboard or cement grade gypsum is the best economic and environmental choice. This paper discusses the supply and demand of gypsum and the impact that the production of synthetic gypsum is currently having and may have in the future.
