The paper discusses combining experimental results from a pilot-scale rotary kiln incinerator simulator with a theoretical model in order to explore the potential of minimizing transient emissions through changes in kiln rotation speed and temperature, steady state oxygen enrichment, and oxygen enrichment in a dynamic mode. Results indicate that transient organic emissions can 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 implemented carefully. Transient emissions of organics occur from rotary kiln incinerators when drums containing liquid wastes bound on sorbents are introduced in batches. Physical processes controlling the release of waste from the sorbent material are greatly affected by the rotation speed and temperature of the kiln. Local partial pressure of oxygen influences the rate of oxidation of the puff formed inside the kiln. These physical and chemical phenomena can be used to control transient emissions by oxygen enrichment, where it is done in either a steady or a dynamic mode.
