Commercial experience has shown that fresh slurry pH as it enters the absorber should be in the range 5.5–6.0 for limestone systems (Wang et al., 2005). As the SO 2 is absorbed from the flue gas, the slurry becomes more acidic and the pH drops. The pH of the spent slurry as it leaves the absorber is in the range 4.0–5.0 for limestone …

What is limestone slurry pump? In the limestone-gypsum wet flue gas desulfurization process, limestone is used as desulfurization absorbent, and the function of limestone slurry pump is to send the limestone slurry in the preparation tank to the absorption tower. The pump is a single-stage single suction horizontal centrifugal pump. Control of ...

During the operation of the wet mill pulping system, the limestone slurry was pumped from the reservoir to the test section for real-time acquisition of ultrasonic signals. Eventually, the slurry flowed to the slurry tank at the bottom. For the pulse-echo mode, however, the ultrasonic probe was first placed in the water to obtain the …

Neither lime nor limestone dissolves well in water and therefore, both are pumped in slurry form to the scrubber tower. Lime slurry is more alkaline, having a pH of 12.5 while limestone slurry is roughly neutral. A lime based system will therefore add more lime when pH drops below 12 and a limestone based system will be controlled around 6. …
