Air Control Techniques, P.C. has developed a photochemical system to
destroy tetra-octa substituted polychlorinated dibenzo-p-dioxins and
polychlorinated dibenzofurans (dioxin-furans) in industrial gas
streams. The system operates by accelerating naturally occurring
chemical reactions to ensure that the dioxin-furan concentrations are
minimized prior to release from the stack. The necessary equipment can
be retrofitted into existing air pollution control systems.
Photochemical control systems should be installed only after means
to suppress dioxin-furan formation by gas stream temperature reduction
or raw material substitution determined to be infeasible or
economically unreasonable. Air Control Techniques, P.C. can help
industrial clients determine when dioxin-furan control can be achieved
solely through these process modifications and when supplemental
control using photochemistry is needed.
