Emissions of dimethylformamide (DMF) from the Butacite® Tinting Process are reported as
both a Volatile Organic Compound (VOC) and as a Hazardous Air Pollutant (HAP). All
emissions of DMF are from the multi -stage horizontal spray water scrubber (BCD -DI) that
has a documented DMF control efficiency of 97%.
DMF Before -Control Emissions:
The before -control DMF emission rate is determined by the hours that each of the various
tinted bandwidths are produced during the year. The hours of production for a specific
bandwidth is then multiplied by the DMF emission factor for that bandwidth to determine the
before-contol quantity of DMF that would have been emitted from the tinting process. The
emitted DMF quantities for each bandwidth is then summed to obtain the total before -control
DMF emission quantity. That determination is shown in the preceeding Butacite® Tinting
Process DMF Emissions Report.
For 2004 , the before -control DMF emission to the scrubber was 30,557.9 pounds.
DMF After -Control Emissions:
Before -control DMF emissions = 30,557.9 pounds
DMF control efficiency of the Tinting water scrubber (BCD -DI) = 97%
After -control emissions utilizing the 97% control efficient water scrubber (BCD -DI):
After -control DMF emissions would be: 100% — 97% = 3% of the incoming DMF
Therefore, after -control emissions = 30,557.9 pounds
X 3%
916.7 pounds DMF
