  • Flue gases: Gypsum dewatering in desulphurisation

    IntroductionGypsum Dewatering Process StageMachines For Dewatering GypsumConclusionsWet scrubber processes are most commonly used for flue gas desulphurisation (FGD). As well as SO2 and SO3, HCl and HF, fine particulate matter and some air-borne toxins can be removed simultaneously . Wet FGD technologies can be grouped into those that use calcium-based sorbents, magnesium-, potassium- or sodium-based sorbents, ammonia, and seawater. In particular, limestone-based gypsum processes dominate for large scal在filtsep上查看更多信息预计阅读时间:10 分钟

  • Preparation of α High-Strength Gypsum from FGD

    This paper introduced the characteristics of α high-strength gypsum preparation from FGD gypsum by autoclaved semi-dry process. The compositions of the product in different stages of the reaction and the effects of crystal modifiers on the morphology of the α-HH crystals were examined and compared. The properties of α-HH and the feature of hydration products of α-HH were investigated.
