Accurate pH Measurement in Limestone Scrubber

A pH sensor in a recirculating tank is used to control feed of the solid lime or limestone. Neither lime nor limestone dissolves well in water and therefore, both are pumped in slurry form to the scrubber tower. In this process, it is important to promote the reaction of calcium (Ca) and to achieve a target desulfurization rate.
