Thermo Fisher Measures Mercury from the Beginning to end of the Cement Process, Highlighted at ACHEMA 2012
Thermo Instruments is measuring mercury from the beginning to the end of the cement process. The mercury in the raw limestone is measured with X-ray spectrometry. The stack gas mercury is measured by the Thermo mercury CEM system. Cement plants are forced to use the limestone in the vicinity of the plant as a raw material. Transportation costs are too high to consider imports from other areas. The amount of mercury in the limestone varies greatly from one locality to another. When the limestone is heated virtually, all the mercury is vaporized and would exit in the stack except for capture in the air pollution control equipment. At the ACHEMA show in Frankfurt, Germany last week, we learned about the extensive use of Thermo XRF spectrometers in cement plants. Here is the unit on display with the characteristics of the instrument explained by Franz Mollekopf.
