The paper discusses the test design for environmental technology verification (ETV) of add-on nitrogen oxides (NOx) control utilizing ozone injection. 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 (LTO) technology is the first NOx control technology planned for verification by the APCT program. LTO 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.
