Jozewicz, W., C. Singer, R K. Srivastava*, AND P. E. Tsirigotis*. STATUS OF SO2 SCRUBBING TECHNOLOGIES. Presented at Mega Symposium, Atlanta, Georgia, 8/16-20/99.
Description:
The paper presents the extent of current sulfur dioxide (SO2) scrubber applications on electricity generating units in the U.S. and abroad. The technical performance of recent SO2 scrubber installations is discussed. Recently reported technical innovations to SO2 scrubbing technologies are also reviewed. Data on mercury removal achieved with scrubbers are presented and discussed. Current advances in scrubbing technologies to improve mercury capture are also presented. (NOTE: SO2 scrubbers may be used by some electricity generating units to meet the requirements of Phase II of the Acid Rain SO2 Reduction Program, which begins on January 1, 2000. Additionally, the use of wet scrubbers can result in reduction of fine particle precursor and mercury emissions from combustion units. It is timely, therefore, to examine the current status of SO2 scrubbing technologies).
