Can you recommend combustion equipment options for a 1,000 scfm off gas stream from a WWTP dissolved nitrogen flotation (DNF) unit? This inermittent stream (as little as 30 minutes/day) is saturated with water vapor at approx 100°F and also includes up to 30 lb/min organics (approx 15% by volume), mostly BTXE (benzene, toluene, xylenes, and ethylbenzene) and MTBE (methyl tert-butyl ether). The required efficiency is greater than 95%. Note, the DNF unit is covered and operates under a nitrogen blanket.
Have an insight or suggestion?

Re: Efficient combustion equipment options18 October 2006 at 1:29pmThe most appropriate solution to this problem is a catalytic thermal oxidizer which can oxidize the organics to CO2 and H2O at at temperature of about
450-500°F. Fuel costs will me minimal and the catalytic thermal oxidizer will be able to achieve the 95% removal efficiency required. Another solution is a carbon adsorption unit. It is a simpler device to operate.
