Description:Emissions of VOC's are subject to control by the EPA both because VOC's are regarded as ozone precursors and because many specific VOC's are hazardous air pollutants (HAP's) under the Clean Air Act Amendments. A number of industries generate offgases with both fine particulate matter and VOC's and require emission control technology for both. The research in this program expands on the successful Phase I proof-of-principal testing of a novel catalytic filter for simultaneous removal of VOC's and particulate matter. The overall objective of the Phase II program is to develop improved catalytic filters which have the performance required for industrial acceptance of the technology. Specific product development technical objectives include the following (at a space velocity of 40,000 hr-1; and operating temperature of about 550?F; and a pressure differential of less than 15 inches water):
- VOC removal efficiency of 95% or greater for a variety of organic vapors, including chlorinated hydrocarbons.
- Substantially complete particulate removal efficiency (>99.9%); and
- Ability to maintain clean catalytic filter pressure drop over repetitive filtration cycles.
- Demonstration of a catalytic filter at an asphalt concrete plant for a 4-6 week period; and
- Development of system installation and operating costs and comparison with costs for conventional technology.
