Process data
Measuring task:
Density measurement
Measuring point:
Pipeline
Measuring range up to:
0.3 m
Medium:
Lime milk
Process temperature:
-40 … +50 °C
Process pressure:
+1 … +3 bar
Special challenges:
Determining exact density of lime milk
Application
The flue gas enters the scrubbing tower (absorber) and cools down further. Here the lime milk (gypsum suspension) is sprayed into the flue gas to wash out the SO2 gas component. The sulphur dioxide is converted into calcium sulphite, which then falls into the absorber sump. To ensure effective flue gas desulfurization, the lime milk (gypsum suspension) must always have a certain density. Radiation-based measurement is used to ensure this.
