5 Chemistry of desulfurization (cont'd) The net result is the transformation of CaCO3 to calcium ions (Ca++), the release of carbon dioxide and production of HSO3 CaCO3 + 2 SO2 + H2O Ca++ + CO2 + 2 HSO3– The carbon dioxide bubbles up as a gas, while HSO3 – remains in the water solution (if the temperature is not too high – see final note below).

The equipment can produce water resistant and highstrength gypsum hollow wall panel and gypsum block by using natural gypsum, desulfurization gypsum or phosphogypsum and solved the technical problems of low strength and poor water resistance of gypsum products. Perfermance Function of Annual Capacity 1,000,000㎡ Gypsum Wall Panel Production
Thus, parameters as desulfurization efficiency, pH value and γ will be selected as factors for gypsum slurry quality monitoring. When dealing with these online data of desulfurization system, it is necessary to handle incremental clustering analysis for gypsum slurry quality monitoring in this paper. 3. Methods
The Process of Desulfurization Gypsum Production Line of Our Company Our technicians started to research the phosphogypsum treatment process and equipments since 2002. In 2003, it was put into appliion and production in Shandong Jinxin Corporation. In 2004, the first Phosphogypsum Production Line
Flue gas desulfurization Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO 2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators.
Gypsum Wall Panel Production Line The equipment can produce water resistant and highstrength gypsum hollow wall panel and gypsum block by using natural gypsum, desulfurization gypsum or phosphogypsum and solved the technical problems of low strength and poor water resistance of gypsum
A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

Are flue gas desulfurization (FGD) systems reliable and operable for scrubbing stack gas effluents from the combustion of high sulfur coal of the eastern United States? It is important to consider this question both in light of the recent large increase in knowledge of FGD technologies and also with
Flue Gas Desulfurization. Appliion. Wet flue gas desulfurization or scrubber systems are an excellent way of reducing the sulfur dioxide emissions caused by coal combustion boilers. The flue gas discharged from the boiler is fed into the absorber. In the absorber, a mixture of water and pulverized limestone is sprayed on the flue gas.
