Theoretical Estimation of Incinerability of Halons and Hydrochlorofluorocarbons

摘要

Theoretical calculations are given for design of thermal destruction conditions for multi-halogenated organicncompounds. Arrhenius parameters and equations were used to calculate relative incinerability of three bromofluorocarbonsn(halon 1301, halon 1211, and halon 2402) and two hydrochlorofluorocarbons (HCFC-22 andnHCFC-123) that are not in the U.S. Environmental Protection Agency Thermal Stability-Based Ranking of HazardousnWaste Incinerability. Halons and HCFCs evaluated in this report have Incinerability Indices that ranknbelow Class I. Thus, they may be disposed of in incinerators that have proven destruction and removal efficiencyn>99.99% for at least one Class I principal organic hazardous constituent. A discussion of thermal destructionnmechanisms of these compounds is given. Thermal destruction may result in products of incomplete combustionnthat exhibit ozone-depleting or global-warming potential. Additional theoretical and possibly experimentalnevaluations will be required to address these issues.
