The combustion of flue gas from thermal power plants contains a lot of harmful substances, which will cause serious pollution to the environment when discharged into the atmosphere. FGD-Flue Gas Desulphurization is the removal of sulfide (SO2) from flue gas. Flue gas desulfurization equipment can remove most of the sulfides from the flue gas and meet emission standards to protect the environment.

Main desulfurization method

The wet process of fgd: flue gas is reacted by an absorbent contained in an aqueous solution, and the absorbent may be a material such as ammonia or sodium sulfite. However, lime or limestone slurry it is widely used as an absorbent. The flue gas contacts with lime or limestone slurry in the spray tower. The calcium in the slurry reacts with SO2 in the flue gas to generate gypsum. Meanwhile, other pollutants in the flue gas, such as dust, HF and SO3, are removed.

Application of high pressure pump in wet flue gas desulfurization

A large circulating pump circulates the limestone slurry to the tower. In addition, this process also requires these pump equipment: slurry circulation pump, gypsum slurry pump, water pump, defogger flushing pump, limestone slurry pump, pit pump, recovery pump, various lubricating oil pumps, hydraulic oil pump etc.
