SUBJECT Vent Sampling
The Organics Classifier Scrubber Vent has been recharacterized for chlorinated hydrocarbon emissions.
The vent was characterized in May, 1982 and was found to be a continuous emission source with a flow rate of =46 ft3/min emitting 650-1200 lb/day chlori nated hydrocarbons. The nitrogen pad pressure was 2.5 in. Ha0 and the water seal pressure was 3.0 in. Ha0. The vapor pressure due to the light chlorinated hydro carbons in combination with the nitrogen pad pressure was enough to overcome the water seal resulting in a continuous flow through the vent. The AP was increased to 1.5 in. Ha0 by increasing the water seal to 4 in. Ha0.
The procedure of recharacterization was to sample the vent while tar buggies and vacuum trucks were dumping into the classifier, and during periods where no "dumping" was taking place. In order to sample during all operating conditions, the vent was sampled as the sludge built up to capacity which normally takes three to four weeks.
The minor changes made on the system have significantly reduced chlorinated hydrocarbon emissions.
Attached is a series of analyses and a graph of velocity data gathered during dumping operations.
It is strongly recommended that tar buggy operators and labor personnel wear respiratory protection in the area.
