Coal fly ash separation plants to be built
Apex Bulk Technologies, Inc. announces a multi-year
agreement with Tribo Flow Separations, LLC of Lexington, Kentucky to design and build dry combustion fly ash separation plants in North America to recover saleable products for use in concrete. Dr. John Stencel of Tribo Flow Separations has performed extensive work on separating unburned carbon in the fly ash from coal fired electric utilities resulting in seven US and International patents.
Fly ash with high carbon or LOI (Loss on Ignition) content is usually sent to a landfill or an impoundment. As a consequence, any economic value that the fly ash has is lost and a long-term financial and environmental burden is taken on by the company owning the impoundment. Furthermore, over time the landfill will become completely filled with the fly ash and additional space will have to be engineered to accommodate continued disposal. Under certain circumstances ash impoundments have been known to rupture, potentially causing catastrophic damage to
humans, plants and animals.
