Abstract The SOx NOx ROx Box™ (SNRB) process, or the Babcock & Wilcox patented hot catalytic scrubbing baghouse, is an advanced air pollution control system for the combined removal of sulfur oxides (SOx), nitrogen oxides (NOx), and particulates emitted from fossil-fired boilers or processes. The key to the SNRB process is a high-temperature baghouse in which simultaneous SOx, NOx, and particulate removal occurs. SOx removal is accomplished by injecting a dry sorbent such as hydrated lime or sodium bicarbonate into the flue gas. NOx removal is accomplished in part by ammonia injection with a selective NOx reduction catalyst. Finally, the particulates and spent SOx sorbent are collected in a high-temperature baghouse. The SNRB process offers the advantages of high removal levels of SOx, NOx, and particulate with only a single major component - a high-temperature baghouse. Additional benefits include the simplicity in handling of dry materials, increased catalyst life, and the potential for improving the boiler/turbine cycle efficiency. Babcock & Wilcox (B&W) is currently being funded by the U.S. Department of Energy (DOE) and the Ohio Coal Development Office (OCDO) under the DOE Clean Coal 2 program to demonstrate the feasibility of the SNRB process in a 5 MWe field demonstration. This paper describes the SNRB technology, provides an update of the project status, presents some results from recently completed pilot tests, and describes the field demonstration design and testing plans at the R.E. Burger station of Ohio Edison.
