ABSTRACT:
Processes and oxidizing agents for oxidizing sulfide ion found in sour water to innocuous, soluble sulfur species are provided. The processes basically comprise contacting the sour water with a nitrogen halogenated triazine or a nitrogen halogenated derivative thereof for a period of time sufficient to convert the sulfide ion to sulfate ion. The processes are particularly useful for removing sulfide ion from oil field produced waters, particularly waters associated with secondary recovery or enhanced oil recovery operations.
