the waste from one medium to another; incineration generates chlorinated products of incomplete combustion as well as NOx, and the other oxidation technologies consume appreciable energy. Therefore, several technologies have emerged for providing de-
composition of CVOCs into innocu-
ous compounds, while at the same time potentially reducing operat-
ing costs. The purpose of this test-
ing program is to systematically evaluate emerging technologies for the abatement of atmospheric emissions of CVOCs. Classes of technologies and the outfits re-
sponsible for their development (in

parenthesis) include: (1) free-radi-
cal oxidation processes, such as high-energy corona (PNL), cold plasma (LANL), Xenon Flashlamps (Purus), photocatalytic oxidation (NuTech and the University of Wisconsin), and ozone-enhanced oxidation process (Ultrox); (2) car-
bon regeneration processes, such as desorption and regeneration process (NuCon), and (3) catalytic oxidation (Johnson & Matthey's Allied Signal). Although this report highlights the high-energy corona and VOC recycle/recovery, several other technologies are being de-
monstrated and data will be avail-
able towards the end of FY94.
