The approach pursued by Owens-Corning Fiberglas (OCF), under the Ohio Coal Development Office sponsorship, was to control NO[sub x], particulates and SO[sub x] in one unit by using a catalyst-coated fabric. Owens-Corning Fiberglas Corporation (OCF) has demonstrated the feasibility of controlling particulates and nitrogen oxide emissions with such a fabric on a bench-scale level. In this process, NO[sub x] emissions can be reduced by 90%. Ammonia is injected in the flue gas; in the presence of a catalyst, it reacts at 650[degrees]F with the nitrogen oxide to form nonpolluting nitrogen and water. The fabric is made of S-glass that can readily operate at the required temperature; the catalyst is coated on the fabric, using a proprietary process developed by OCF. Small scale tests had shown that the use of a glass fabric to support the catalyst permits extremely efficient use of the catalyst (10 to 100 times more efficient than present SCR technology). SO[sub x] was eliminated by alkali injection. Combining filtration, NO[sub x] and SO[sub x] reduction in one operation would be significantly more economical than using a filter bag or electrostatic precipitator, an SCR unit, and a desulfurization system.
