gypsum hemihydrate production plant

This work aimed to investigate the feasibility of utilizing the lowquality desulfurization ash from semidry flue gas desulfurization by mixing with αhemihydrate gypsum, and then the environmental issues resulted from lowquality desulfurized ash from semidry flue gas desulfurization can be resolved, and both economic and ecological benefits are brought to the related industries.

question whether the FGD gypsum forming in this power plant could be used for the production of gypsum binder could be answered. The aim of the research is to determine an influence of technological parameters such as temperature and duration of isothermal curing to the crystals morphology and to the properties of αhemihydrate gypsum.
