ENV-10-04 FCCU Flue Gas Scrubbing for Particulate and Sulfur Dioxide Removal – A Tutorial

Description:

The Los Angeles Area Air Basin of Southern California is a nonattainment area for fine particulate matter less than 2.5 microns (PM2.5) [1]. The South Coast Air Quality Management District of California (SCAQMD, the District), the agency charged with developing, implementing, and enforcing air pollution control rules and regulations in the basin, must therefore adopt or modify the necessary regulatory framework to achieve compliance with the Federal PM2.5 standards. These efforts include reduction of direct PM2.5 emissions as well as PM2.5 precursors – sulfur oxides (SOx), oxides of nitrogen (NOx), ammonia (NH3), and volatile organic compounds (VOCs). Reductions of SOx and NOx have been identified as the most effective in achieving attainment status. SCAQMD has recently conducted a study concerned with SOx emission reductions at a number of industrial sources within its jurisdiction, including fluid catalytic cracking units (FCCUs) at petroleum refineries.
