Description:
The paper gives results of a review of commercially available flue gas desulfurization (FGD) technologies that have an established record of performance. Data on worldwide FGD applications reflect that wet FGD technologies have been used at most of the installations. Among the worldwide FGD technology installations completed through 1998, most (522 out of 668) consist of wet FGD systems. The sulfur dioxide (SO2) removal performance of scrubbers has been reviewed. Data reflect that most wet limestone and lime spray drying installations appear to be capable of about 90% SO2 removal. Advanced state-of-the-art wet scrubbers can provide SO2 removal in excess of 95%. A review of recently reported advancements in SO2 scrubbing technologies is presented. Some of these advancements have been aimed at improving the performance and cost-effectiveness of established processes. Examining the cost of limestone forced oxidation (LSFO) applications was particularly interesting since this technology represents the bulk of the Acid Rain SO2 Program Phase I retrofits. A recent cost estimating model, CUECost, can provide the published LSFO costs within +/- 10%.
