Abstract: There is described a process for treatment of a fluid comprising an oxidizable contaminant. The process comprises the step of contacting the wastewater with a combination of: (i) a sulfide, (ii) a complex of Fe(III) and a chelating agent, and (iii) an oxidant. It has been discovered that of treatment of a fluid containing an oxidizable contaminant employing iron(III)-chelates as the Fenton catalyst may be significantly improved by including a sulfide in the reaction scheme. As described herein, by employing sulfide ion, the present inventors have been able to: (i) increase the rate of iron recycling from minutes or hours to a few seconds, and (ii) destroy benzene in an oil and gas refinery (OGR) wastewater in less than one minute. It is believed that these findings in OGR wastewater can be extended to other fluids containing other oxidizable contaminants.

Abstract: Described is a process for treatment of a fluid comprising an oxidizable contaminant selected from one or both of a sulfide and a thiol, the process comprising the step of contacting the fluid with a first complex of ferric iron and a polyphosphate to oxidize the oxidizable contaminant and generate a second complex of ferrous ion and the polyphosphate.
