Abstract
A method for reducing the amount of hydrogen sulfide present in liquid hydrocarbon media while minimizing the amount of corrosion in processing equipment contacting the liquid hydrocarbon media. The method includes neutralizing a glyoxal solution and dispersing the neutralized glyoxal solution in the liquid hydrocarbon media. The neutralized glyoxal solution is dispersed within the liquid hydrocarbon media not more than 10 days after the glyoxal solution has been neutralized. A hydrogen sulfide scavenging composition and method for making are also provided.
