Description

Here, "desulfurization slag" refers to a solid by-product generated and discharged when removing sulfides from flue gas or other gases using wet or dry desulfurization processes in coal-fired power plants, metallurgical, chemical or other industrial processes, with calcium sulfate and calcium sulfite as the main constituents and small amounts of unreacted absorbent and impurities. After such desulfurization slag has lost its original process function or been discarded, following dewatering, stabilization and impurity removal it can enter the recovery and reuse processes as a building-material raw material, cement admixture or soil amendment material.

Process Description

The "desulfurization residue" here refers to the solid by-products produced and discharged when wet or dry desulfurization processes are used to remove sulfides in flue gas or gas during coal-fired power plants, metallurgy, chemical industry or other industrial processes. The main components are calcium sulfate, calcium sulfite and a small amount of unreacted absorbent and impurities. After this type of desulfurization slag loses its original process function or is discarded, it can be reused as building materials, cement admixtures or soil improvement materials after dehydration, stabilization and impurity removal.
