The objective of this work was to evaluate the performance of sodium c
ompounds in removing halogenated organic and halogenated inorganic spe
cies from gas streams. Tests were conducted which evaluated fluidized
bed, packed bed, and post-flame injection of sodium compounds as metho
ds for high-temperature scrubbing of halogenated compounds in the form
of sodium halides. Methyl chloride destruction at a given temperature
was promoted by the presence of sodium carbonate. Kinetic modeling of
methyl chloride decomposition supports these experimental results. La
boratory and pilot-scale testing demonstrated effective removal (99-99
.9 + %) of halogenated inorganic combustion byproducts using sodium ca
rbonate in packed beds and fluidized beds within reaction times (0.2-3
.0 seconds), temperatures (450-1,050 degrees C), and other conditions
which are in the practical range for application to waste incineration
.
