Show 3.0 Results All test modes produced satisfactory results. No sludge balls were produced. The sludge dispersed itself well in all cases. All test runs were spiked with 2% carbon tetrachloride, 2% chloroform, and 6% methanol. Carbon tetrachloride was chosen as a spike because it currently tops the EPA I s list of most difficult compounds to destroy. Chloroform was chosen because it can be detected on the same VOST sample train and is a possible product of incomplete combustion for our waste mix. Methanol was chosen because of its relative abundance in our waste. A destructon removal efficiency of 99.9999% was achieved on carbon tetrachloride for every run, and a destruction removal efficiency of 99.999% was achieved for chloroform on all runs. The ORE for methanol was not able to be calculated. Run 3A produced carbon monoxide spikes; a direct result of batch feeding solids. The rolling hour average emission of carbon monoxide however did not exceed 25 ppm. The expectation of a high particulate carryover rate was fulfilled in all tests. Roughly fifty one percent of the particulate generated was carried overhead. Table III shows the particulate emissions rates for all tests. TABLE III TOTAL PARTICULATE EMISSIONS IN LBS/HR RUN 1A RUN 1B RUN 2A RUN 2B RUN 3A 5.43 2.71 3.30 2.99 2.66 The initial high value of 5.43 lbs/hr particulate emissions could possibly be attributed to non-steady state conditions. Run 3A , the last run, produced the lowest particulate emissions rate, roughly eight percent below the average rate of runs 1B, 2A, 2B, and 3A. Whether this indicates increased particulate retention in the kiln is indeterminate. If the decrease is indicative of increased particulate retention in the kiln, then there are two possible ramifications. One possibility is that the packaged waste helped to bind the fines produced in the sludge drying and 6 |
