United States Environmental Protection Agency Air and Energy Engineering Research Laboratory Research Triangle Park, NC 27711 Research and Development EPA/600/SR-93/212 February 1994 v?EPA Project Summary Evaluation of the Polyad®FB Air Purification and Solvent Recovery Process for Styrene Removal Larry Felix, Randy Merritt, and Ashley Williamson EPA's Control Technology Center ini- tiated a project to evaluate the Polyad® fluidized-bed (FB) solvent recovery sys- tem for controlling styrene emissions from an operating shower stall/bathtub manufacturing plant. The Polyad® FB system employs macroporous polymer particles as an absorbent that continu- ously migrates from an absorption sec- tion to a desorption section where the particles are regenerated and the sol- vent is condensed and recovered. The Polyad® FB pilot unit was evaluated on a styrene-contaminated exhaust air stream from a gel coat spray booth at Eljer Manufacturing Company in Wil- son, NC. Inlet and outlet styrene con- centrations were measured on the Polyad® FB unit using Total Hydrocar- bon Analyzers. The Polyad® FB unit displayed the capabilities of control- ling greater than 95% of the styrene being emitted to the atmosphere. Sys- tem capital cost and applicability to a facility similar to Eljer were also evalu- ated. This Project Summary was developed by EPA's Air and Energy Engineering Research Laboratory, Research Tri- angle Park, NC, to announce key find- ings of the research project that is fully documented in a separate report of the same title (see Project Report ordering information at back). p Printed on Recycled Paper ------- L.
