Abstract
Processes and apparatuses converting poly- and perfluoroalkyl substances (PFAS). An oxidation reaction zone, preferably a thermal oxidizer, is used to oxidize the PFAS into fluoride species. A reaction zone having at least one reactor containing a solid reactant for neutralizing the fluoride species is provided. The solid reactant is also configured to degrade any PFAS remaining in the effluent from the oxidation zone. A cooling zone, for example, a quench zone may be between the reaction zone and the oxidation zone. The PFAS may be liquid PFAS that is injected into the thermal oxidizer.
