The extracted air stream first enters the <br /> preheater burner chamber. The air stream from the preheater then enters <br /> the catalytic bed where oxidation of the hydrocarbon vapor occurs. <br /> The catalyst has a hydrocarbon destruction efficiency of at least 95% <br /> when the TVH influent concentration is above 1000 <br /> M. When the concentration is 1000 ppm or lower, the TVH destruction efficiency nisugo% <br /> or better.
