Description:
The report gives results of performance tests to determine the fine particle collection of four novel scrubbers: a Lone Star Steel Steam-Hydro Scrubber, an Aronetics (Chemico) Two-Phase Jet Scrubber, an Entoleter Centrifield Scrubber, and a CEA Variable-Throat Venturi Scrubber. The energy consumption of the scrubbers ranged from about 3000 to 400,000 J/std cu m (dry). Collection efficiencies for 1-micrometer diameter particles ranged from about 75% for the collector operating with the lowest energy consumption to 99.995% for the highest. Fractional collection efficiencies were measured using a variety of inertial, optical, diffusional, and electrical methods for particle diameters of from about 0.01 to about 5 micrometers for each device tested. In addition, the overall collection efficiency was measured using either EPA Method 5 or 7. Two of the devices were controlling emissions from primary metallurgical processes; one, from an asphalt batching plant; and one, from a pulverized-coal-fired utility boiler.
