Volatilization Modeling of Semivolatile Organic Compounds During Solidification Processes


Technical information is provided on the effects of temperature elevation on increasing the volatility of semivolatile organic compounds (SVOCs) in stabilization media. A chemical diffusion model was developed (1) to establish a technical basis for determining maximum treatment temperatures above which SVOCs should not be exposed during solidification processes to reduce the potential for unacceptable releases; and (2) to prescribe types of binders with sufficiently low heat output to stabilize organics that have potential for volatilizing with moderate heating, and to recommend against use of others that may not maintain the mixture at sufficiently low temperatures. A non-steady-state model for linear diffusion in the aqueous and vapor phases was used because the SVOC dynamics of diffusion are controlled by resistances in both pore water and air. The results of volatilization calculations performed are presented.
