Abstract
Emission rates of ethyl-alcohol (64175) from a candy glazing operation were determined and expressed as emission factors. Candy was processed in a row of 24 open faced rotating pans, each with a capacity of about 250 pounds of candy per batch with a typical batch cycling time of 20 minutes. Over a 2 day period, 12 1 hour processing periods were monitored. Analysis of the glaze composition by weight percentage, gave 55% ethyl-alcohol on June 13 and 58% on June 14. The average concentration of ethyl-alcohol 1.5 meters in front of the line was above 1000 parts per meter. The average emission rates for 12 periods were 38.4 kilograms/hour (kg/hr), 42.5kg/hr, and 49.6kg/hr for three different forms of the ethanol mass balance around the space. The authors conclude that the emissions from the glazing operation could be reasonably predicted using a completely mixed mass balance model. The emission factor of ethyl-alcohol was in the range of 294 to 500 grams/batch, and this range was in agreement with the emission factor estimated from the composition of the glaze mix and the amount of glaze mix added.
