Enactment of the Clean Air Act Amendments and passage of state legislation leading to more stringent nitrogen oxides (NO.) regulations have fueled research and development efforts on the technologies for the combined control of sulfur dioxide (SO[sub 2]) and NO[sub x]. The integrated removal of both SO[sub 2] and NO[sub x] in a single system can offer significant advantages over the use of several separate processes, including such factors as reduced system complexity, better operability, and lower costs. This paper reviews the status of a number of integrated flue-gas-cleanup systems that have reached a significant stage of development, focusing on post-combustion processes that have been tested or are ready for testing at the pilot scale or larger. A brief process description, a summary of the development status and performance achieved to date, pending commercialization issues, and process economics (when available) are given for each technology.
