Deliverables: Comprehensive and unambiguous quantification of the speciated emissions concentrations from elevated flares as a function of … ¾ flare gas composition ¾ flare/wind momentum flux ratio ¾ steam rate Comprehensive and unambiguous quantification of flare/wind low momentum flux ratio inefficiencies ¾ Downstream "best practice" no flaring purge and pilot only operation ¾ Upstream field flare operation Comprehensive and unambiguous quantification of oversteaming inefficiencies ¾ Downstream operations Identification of measurable operating parameter based "Best Practices" to ensure high efficiency operation of upstream and downstream elevated flares Principal Investigators John Pohl Peter Gogolek Bob Schwartz Jim Seebold Virginia Polytechnic Institute and State University John Zink Company LLC Natural Resources Canada CANMET Energy Technology Centre Chevron(Ret) Effect of Wind ... ?
