FIELD-SCALE ROTARY KILN INCINERATION OF BATCH LOADED TOLUENE SORBENT .1. DATA-ANALYSIS AND BED MOTION CONSIDERATIONS

In this study, a field-scale rotary kiln incinerator was used for expe riments on the processing of toluene contaminated sorbent contained in plastic packs. The incinerator was probed with instruments in several different locations. The result obtained in this study agree in many ways with previous studies on xylene and dichloromethane in the same i ncinerator. The species and temperature stratification observed near t he kiln exit is consistent with previous observations. The moderate mi xing induced by turbulence air addition is similar to that observed du ring the xylene and dichloromethane studies. The bed motion was differ ent from that of previous experiments, and this difference affected th e measured responses. Additional instrumentation has provided a cleare r view of the processes occurring ring within the incinerator and thro ugh the entire system. The second paper in this series will expand upo n the analysis of this data. Mass balances will be performed on the sy stem, the evolution rates of toluene will be calculated, and the chara cteristic times for the toluene evolution will be determined.
