samples were collected to analyze the Hg mass balance. The total Hg concentrations in the raw mill electrostatic precipitator (ESP) input of the two plants were 155.70 and 64.62 µg Nm–3, respectively, which were higher than those at any other sampling point. Approximately 97.5 and 86.5% of the Hg in the raw mill ESP input at Plants 1 and 2,

Mercury species, mass flows and processes in a cement plant

Aug 01, 2010  The annual mercury mass balance and hourly partial mass balance were calculated from selected sets of data. With the data used the difference between inputs and outputs was 11–45%. A better match was obtained with direct mode data. Emission in the annual mass balance was in the range of 40–70% of inputs and cement clinker contributed 10%.
