The heart of the CT121 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.

Absorbent preparation and dosing; Removal of SOx (HCl, HF) Dewatering and conditioning of the product; In this method, limestone (CaCO3) or quicklime (CaO) can be used as the absorbent. The selection of an additive which can be added dry or as a slurry is made on the basis of projectspecific boundary conditions.
Dec 01, 2018· This wet FGD unit was designed by IHI Corporation (Japan) with desulfurization efficiency over 96% for two pulverized coal boilers in that petrochemical company, and it mainly consisted of five systems including limestone preparation system, boiler air and gas system, absorption system, gypsum dewatering system, and waste water treatment 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 .
In air pollution control industry, power plant desulfurization is a hot topic. There are many different kinds of power plant desulfurization methods. For most of the popular methods need to use limestone powder, the preparation of lime powder is very important.
If required, classifier grits can be evacuated for another classification in a downstream Pfeiffer separator and separated into limestone sands ( to mm) in screening machines. Pulverized limestone is used above all as filler and for flue gas desulfurization. Limestone sand is used in building materials.
