Separation Technologies (ST) has commissioned its first industrial scale plant engineered to reclaim fly ash from coal ash impoundment basins. A pilot facility at the Talen Energy Brunner Island Steam Electric Station in York Haven, Pa. combines the Titan America LLC subsidiary’s new proprietary drying and screening system with longstanding electrostatic separation equipment for removing unburned carbon from coal ash. The processes and technologies, debuting in tandem, yield ProAsh, ST’s established ASTM C618 concrete-grade fly ash product; and EcoTherm, an improved material with fuel value plus chemistry suitable for cement production.
Separation Technologies’ reclaiming process at the Talen Energy Brunner Island station entails screening (above) and drying (below) impounded ash, then conveying to an electrostatic separator (bottom) for grading ProAsh Class F fly ash and EcoTherm. The latter can serve as an economical alternative to bauxite and other silicon dioxide, aluminum
Separation Technologies starts new fly ash reclamation process 24 February 2021
Separation Technologies (Titan Cement group) has commissioned the world s first industrial-scale fly ash drying and electrostatic separation plant to reclaim fly ash from nearby coal ash basins.
Located at Talen Energy s Brunner Island Steam Electric Station, the pilot facility combines Separation Technologies’ new proprietary drying and screening system and electrostatic separation for removing unburned carbon from fly ash for use in concrete construction. Removing the unburned carbon improves the performance of the fly ash in concrete and transforms it from an unusable waste product into a desired and marketable building material. The Separation Technologies’ fly ash reclamation process results in the branded products of ProAsh
