Correcting the gas and particle partitioning of PCDD/F congeners in the flue gas of an iron ore sinter plant

► We propose a new approach to correct gas/particle partitioning of flue gas PCDD/Fs. ► Validity of correction is assessed by examining the removal efficiencies of APCDs. ► After correction, PCDD/Fs in the flue gas is dominated by the gas-phase. ► After correction, the removal efficiencies of installed APCDs become more reasonable.
