Title Pressure-assisted flare emissions testing
Date 2007
Description Due to increased concern regarding air emissions of highly-reactive volatile organic compounds (HRVOC) in the Greater Houston area, emissions from various sources in the area are now subject to much more scrutiny by the Texas Commission on Environmental Quality. One potential source of emissions is from flares whose design and operation is addressed by the EPA through the Federal Code of Regulation 40-CFR Section 60.18. In particular, this standard sets forth the relationship between volumetric heating value of the flare gasses and the maximum allowable exit velocity. Depending on the specific flare type and gas heating value, maximum allowable exit velocities are generally limited to less than about 400 feet per second. This code was originally developed around non-assisted, air-assisted, and steam-assisted flare technology. Pressure assisted flares are not specifically addressed by the regulation. Pressure assisted flares often operate with an exit velocity of about Mach 1.0, which is much higher than allowed by 40-CFR-60.18. In partnership, John Zink and Dow set out to demonstrate that the destruction efficiency for pressure assisted flares is equal to or better than other flare types, even though the exit velocity is higher. Several different pressure assisted flare burners were tested using various gas mixtures, and the emissions from the flames were captured and measured.
