Fgd residues: a commercial opportunity
- Conversion Systems, Inc., Horsham, PA (US)
This paper focuses on actual operating experience in the handling and processing of ash and FGD by-products by Conversion Systems at the Orlando Utility Commission Stanton Energy Center at Orlando, Florida. The discussion discloses how the Poz-O-Tec stabilization technology, the most widely used disposal technology for wet FGD sludge, has been modified and improved to maximize the by-product recycling and produce the most cost effective disposal option. Recently, CSI has directed 100% of the Stanton Facility FGD stabilization production into the generation of the commercial aggregate called Poz-O-Lite Aggregate. This aggregate product is used in the manufacture of concrete block, replacing ordinary crushed stone. CSI has been able to develop this reuse application using the low permeability and superior strength of the stabilized material. The utility also benefits from the stabilized material which is not recycled as it offers opportunity for co-disposal of other combustion residues from some of the utility's oil fired plants in cells that are lined and then capped with the stabilized material. In summary, virtually all production of the by-products, from combustion or flue gas desulfurization at the Stanton Energy Center are now being used for commercial application, except that specifically required as liners for the disposal of other materials on site.
