Gypsum from Power Plants: An Antidote to Algal Blooms
As a plentiful power plant by-product, flue gas desulfurization gypsum offers great potential to improve water quality and protect aquatic ecosystems by reducing phosphorus runoff from fertilized fields, an EPRI study reveals. Such runoff can degrade surface water quality and cause algal blooms. These have led to the temporary loss of drinking water in Toledo, Ohio and the …

Detailed modelling of a flue-gas desulfurisation plant
This paper presents a CFD model for a flue-gas desulfurisation plant, and its application to an operating plant. The FGD plant is of the wet-scrubber type, with co-current and counter-current sections. The sorbent used is limestone, and, after cleaning the flue gases, the limestone slurry is collected in an oxidation tank for the production of gypsum. . The model …
