StateMaster - Encyclopedia: Flue gas desulfurization. Flue gas desulfurization is technology that employs a sorbent, usually lime or limestone, to remove sulfur dioxide(SO2) from the gases produced by burning fossil fuels.This is not a problem in a kraft pulp mill for example, where this can be a source of makeup chemicals to the recovery cycle.
The Phoenix System is the result of time-tested operational installations of Flue Gas Desulfurization (FGD) process. Using the latest technology coupled with our application experience, this approach provides a greater process-oriented solution than simply re-deploying outdated equipment to new tasks.
Limestone/ gypsum dry process/ semi dry process/ wet process desulphurization is a process to desulfurize flue gas. It has the advantages of mature technology, low investment, high efficiency, low operating cost, and is suitable for large capacity units. It is the most widely used desulfurization process in the world. ... Ball Mill. Get Price.
The flue gas desulfurization technology is more mature. Therefore, for a long time in the future, China's national conditions and technical conditions have decided that the key and effective means to control sulfur dioxide emissions from thermal power plants is flue gas desulfurization. ... Ball Mill; HGM Three-ring Grinding Mill;
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.
