Mercury species, mass flows and processes in a cement ...

01/08/2010  Many mercury loops were found in the cement clinker production process. Consequently mercury mass flows inside the process were largely increased due to constant Hg recycling. The emitted mercury mass flow was in the range of 0.1–2.4 g/h, while the internal flows could be up to 20 g/h on one line with some even higher peaks. Maximum mercury ...

Mercury species in flue gases at characteristic parts of the process were measured as total Hg(t), particulate Hg(p), elemental Hg 0 (g) and reactive Hg 2+ (g) mercury. Based on the results of measurements, mercury mass flows and mass balances of the whole and in certain parts of the process were evaluated. It was shown that the process comprises many mercury cycles which are

Mercury species, mass flows and processes in a cement plant

The aim of the study was to evaluate the behaviour of mercury in the cement clinker production process. Simultaneous measurements of mercury in all important materials and gas streams were performed in three sampling periods on about 300 solid samples and about 80 samples taken from gas streams. Mercury species in flue gases at characteristic parts of the process were measured as total
