Clear liquor scrubbing with anhydrite production. Third quarter 1996 technical progress report
This project is part of PETC`s Advanced Power Systems Program, whose mission is to accelerate the commercialization of affordable, high- efficiency, low emission, coal-fueled electric generating technologies. A process concept - Clear Liquor Scrubbing with Anhydrite Production - was proposed and accepted by PETC as a Phase I project in its Mega-PRDA program. The project integrates three process operation - chloride control upstream of the flue gas desulfurization (FGD) system, a clear liquor process for enhanced SO{sub 2} removal performance, and production of anhydrite (anhydrous calcium sulfate) rather than calcium sulfite or gypsum (calcium sulfate dehydrate). the first step in the project was to perform batch and flow-through experiments in the laboratory to confirm theoretical calculations and preliminary laboratory results concerning anhydrite formation. these laboratory experiments were designed to prove that anhydrite can be produced under conditions that can be reasonably achieved in a process external to an FGD system. Since gypsum is the kinetically favored sulfate species at typical FGD conditions, parameters needed to be identified so that production of reasonably pure anhydrite at reasonable rates could be demonstrated prior to further development of the anhydrite process at the pilot scale. This quarterly technical progress report communicated the important findings of the project during the July-September 1996 calendar quarter.
