A comparison of in situ vitrification and rotary kiln incineration for soils treatment.
In the hazardous waste community, the term "thermal destruction" is a catchall phrase that broadly refers to high temperature destruction of hazardous contaminants. Included in the thermal destruction category are treatment technologies such as rotary kiln incineration, fluidized bed incineration, infrared thermal treatment, wet air oxidation, pyrolytic incineration, and vitrification. Among them, conventional rotary kiln incineration, a disposal method for many years, is the most well established, and often serves as a barometer to gauge the relative success of similar technologies. Public sentiment on environmental issues and increasingly stringent environmental regulations has, over time, spurred design and development of innovative thermal treatment processes directed toward reducing harmful emissions and residuals that may require further treatment or disposal. In situ vitrification (ISV), a technology that combines heat and immobilization, is one such innovative and relatively new technology. This paper presents a comparison of ISV and rotary kiln incineration for soils treatment in the areas of process performance, process residuals, process limitations, applicable or relevant and appropriate (ARARs) regulations, criteria and limitations, and costs.
