Recent advances in flue gas desulfurization gypsum

01/12/2019 Flue gas desulfurization gypsum (FGDG) is an industrial by-product generated during the flue gas desulfurization process in coal-fired power plants. Due to its abundance, chemical and physical properties, FGDG has been used in several beneficial applications. However, during the past decade, the rate of beneficially used FGDG has gradually decreased, while its production has drastically

BUILDING MATERIALS MADE FROM FLUE GAS DESULFURIZATION

Flue gas desulphurization (FGD) materials are produced in abundant quantities by coal burning utilities. Due to environmental restrains, flue gases must be “cleaned” prior to release to the atmosphere. They are two general methods to “scrub” flue gas: wet and dry. The choice of scrubbing material is often defined by the type of coal being burned, i.e. its composition. Scrubbing is

Gypsum as an Agricultural Amendment: General Use Guidelines

Flue gas desulfurization (FGD) gypsum is created in limestone-forced oxidation scrubbers that remove sulfur dioxide from the flue gas stream after coal combustion. In general, a wet scrubbing process first exposes the flue gases to a slurry of hydrated lime. Capture of SO₂ by the lime slurry initially forms calcium sulfite (CaSO₃•0.5H₂O).
