 This unit is a tightly closed 300-gallon mixer, with a batch weight of 3107 pounds. Cover openings for bulk liquid fill lines and the mixer shaft are mimimal. Bulk filler addition is via closed hopper.  The mixer is continuously swept with nitrogen at a rate of about 60 dscfm. The paste had a monomer content of 17.4% wt styrene as run.

Method: VOC emission test, per protocol approved by Ohio EPA. Mixer was deemed to meet Method 204 and was assumed to capture 100% of emissions.

Agency Witness: Christine McPhee, North East District Office, Ohio EPA,  330-425-9171

Test Description: The test was conducted 9/18/97, and consisted of three runs of the same resin formulation. Styrene was the only VOC emitted.

Emission Factor: 0.0002492 lb OC emitted / lb OC available (average of three runs)
Assuming an uncovered emission factor of 0.01, pollution prevention by installation of this cover reduced styrene emissions by 97.51%.
