A lime based system will therefore add more lime when pH drops below 12 and a limestone based system will be controlled around 6. Unless one or the other is added, the SO ... Lime / Limestone Wet Scrubbing System for Flue Gas Desulfurization Application Data .
The limestone desulfurization used is gypsum desulfurization, limestone is made into lime powder by limestone Gold Ore Refining Process Equipment, and then water is added to make the slurry pumped into the absorption tower to fully contact with the flue gas, and the calcium carbonate in the slurry and the lower part of the tower are blown in.
A comparison of system characteristics between seawater FGD and wet limestone FGD is given in Table 4. The comparison is based on a 600-MWe power plant utilizing coal having 1% sulfur. Based on the information presented in Table 4, it is obvious that the seawater FGD system is technically and economically better than the wet limestone system.
Limestone FGD New Technology Connection of water from the water supply system to the desulfurization Island has two, all the way to industrial water, the other way is the main circulating water industrial water users: mist of water, gypsum is washed with water circulating water main users: the limestone slurry preparation water, flue gas heat exchanger flushing .
Advantages of the Marsulex Ammonium Sulfate System The system is designed with standard conventional critical equipment redundancy similar to that of limestone based systems. This similarity upstream of the centrifuge allows flexibility to operate the flue gas desulfurization system with either limestone or ammonia as a reagent.

The heart of the CT-121 FGD process is the unique Jet Bubbling Reactor (JBR). All necessary steps for SO 2 absorption, oxidation, neutralization and crystallization occur simultaneously in the JBR. The flue gas is dispersed into the scrubbing liquid through multiple gas sparging tubes, creating small bubbles which are broken by the liquid's motion.
