With funding from EPRI and Public Service Electric and Gas (PSE and G), ADA Technologies has been operating a COHPAC (COmpact Hybrid PArticulate Collector) pulse-jet pilot plant at PSE and G's Hudson station in Jersey City, NJ to expand the application of COHPAC in anticipation of hazardous air pollutants (HAP) regulations. The pilot extracts a slipstream of flue gas from downstream of Hudson's full-scale ESP (a four-field Research Cottrell unit). A series of tests has been run over the past two and one-half years to evaluate the injection of dry sorbents upstream of the COHPAC pilot for removal of acid gases and mercury from the flue gas slipstream. The COHPAC baghouse subsequently removes the sorbent material from the flue gas. Gas samples were taken upstream of sorbent injection and downstream of the pilot to characterize the ability of the sorbents to remove targeted HAPs. The operation of the pilot was also monitored during testing to characterize the impact of sorbent injection on the performance of the baghouse. Data collected during 1998 are compared to data from 1997, when the pilot was operated at a higher air-to-cloth ratio.
