NOx, SO3 in the spotlight at NETL's 2006 environmental controls conference
As emissions caps drop, technological solutions must become increasingly effective and efficient. Researchers, equipment vendors, and plant operators are exploring alternatives to SCR and SNCR, with a view to reducing the overall costs of NOx reduction. They've also achieved 95% to 99% removal of SO3, with no visible plume opacity.
