Description:
Transient emissions of organics can occur from rotary kiln incinerators when drums containing liquid wastes bound on sorbents are introduced in a batch-wise fashion. Physical processes controlling the release of waste from the sorbent material are greatly affected by the rotation speed of the kiln and the kiln temperature. Local partial pressure of oxygen influences the rate of oxidation of the puff formed inside the kiln. These physical and chemical phenomena can be exploited to effect control of transient emissions by oxygen enrichment, where this is accomplished in either a steady or a dynamic mode. Experimental results from a pilot-scale rotary kiln incinerator simulator were combined with a theoretical model in order to explore the potential of minimizing transient emissions through changes in kiln rotation speed, kiln temperature, steady oxygen enrichment, and oxygen enrichment in a dynamic mode. Results indicated that transient organic emissions could indeed be minimized by changes in these kiln operating parameters, but because of the complex interactions of physical and chemical processes controlling emissions, the appropriate abatement procedures must be carefully implemented.
