Limestone scrubbing is the method of choice for coal-fired plants, yielding efficiencies of 90% - 98%. SO2 is neutralized by direct contact with limestone slurry in an absorption tower. Slurry is produced by crushing limestone in a ball mill and mixing it with water. During this slaking process, conversion to calcium hydroxide is achieved.The limestone slurry preparation system is for common use of 2 sets of FGD device.The limestone slurry preparation system is designed per uncer COAL E operation situation in scope. The limestone is transported by truck to grinding shop within desulphurization island. With particle size under 20mm, the limestone goes into limestone silo ...
