Process for removal of hydrogen sulfide in downhole oilfield applications

A method and system remove hydrogen sulfide from a sour liquid. In an embodiment, the method for removing hydrogen sulfide from a hydrocarbon containing fluid includes contacting a methylmorpholine-N-oxide solution with the sour liquid. The method also includes allowing the methylmorpholine-N-oxide...

Zusammenfassung:	A method and system remove hydrogen sulfide from a sour liquid. In an embodiment, the method for removing hydrogen sulfide from a hydrocarbon containing fluid includes contacting a methylmorpholine-N-oxide solution with the sour liquid. The method also includes allowing the methylmorpholine-N-oxide to react with the hydrogen sulfide to remove the hydrogen sulfide.
