TEST DESIGN FOR ENVIRONMENTAL TECHNOLOGY VERIFICATION (ETV) OF ADD-ON NOX CONTROL UTILIZING OZONE INJECTION
VanOsdell, D. W., J. R. Farmer, A. Trenholm, C. Clapsaddle, AND T G. Brna*. TEST DESIGN FOR ENVIRONMENTAL TECHNOLOGY VERIFICATION (ETV) OF ADD-ON NOX CONTROL UTILIZING OZONE INJECTION. Presented at Formum 2000 (Sponsor: Institute of Clean Air Companies), Rosslyn, VA, March 23-24, 2000.
The paper discusses the test design for environmental technology verification (ETV) of add-0n nitrogen oxides (NOx) control utilizing ozone injection. (NOTE: ETV is an EPA-established program to enhance domestic and international market acceptance of new or improved commercially ready technologies through independent testing which incorporates rigorous quality assurance (QA) procedures. Through ETV, potential purchasers and permitters are provided an independent and credible assessment of what they are buying and permitting). Operated by the Research Triangle Institute, the Air Pollution Control Technology (APCT) program is one of 12 ETV pilot programs. Add-on NOx air pollution control technologies are among those being verified, and the Low-temperature Oxidation (LTC) technology is the first NOx control technology planned for verification by the APCT program. LTC uses ozone injection into the gas phase of a combustion or chemical process waste gas stream to oxidize NOx molecules to higher order NOx, which can be removed by wet or semi-dry scrubbing. Ozone is produced on-site and on-demand from stored oxygen. As a low-temperature process, it can be installed as an end-of-pipe system. The LTO technology was jointly developed and patented by Cannon Technology and BOC Gases; LoTOx is BOC Gases' trademark for large-scale LTO applications.
