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.

Abstract: A method and apparatus for treating waste gas for an solvent-based carbon capture unit. The process involving the use of a dry sorbent injection (DSI) unit to remove sulfur compounds and fine particulate matter from flue gas are described. The treated flue gas is used to preheat the rich solvent stream from the carbon capture unit. Flue gas from an FCC regenerator, for example, is used to make superheated steam and saturated steam. The process allows for increased thermal energy recovery, decreased water utility and increased equipment reliability.

Abstract: Processes and apparatuses converting poly- and perfluoroalkyl substances (PFAS). An oxidation reaction zone, preferably a thermal oxidizer, is utilized to oxidize the PFAS into anionic fluoride species. A treatment zone is utilized on at least a portion of the oxidation zone effluent before the oxidation zone effluent is vented or otherwise released to the atmosphere. The treatment zone may include a dry sorbent injection zone; a selective catalytic reduction zone, a wet scrubber zone; a carbon bed; an ion exchange zone; or any combination thereof.

Abstract: Processes and apparatuses for converting PFAS. PFAS are heated and introduced to a reactant which will convert the PFAS. The PFAS may be in a stream that is a PFAS enriched stream formed by desorbing the PFAS from an adsorbent which removed the PFAS from a contaminant stream. An effluent from the PFAS conversion reaction is treated in a treatment zone and a treated effluent may be released to the atmosphere.
