Abstract
The use of a dialdehyde (e.g. glyoxal) and a nitrogen-containing scavenger (e.g. a triazine) when injected separately in media containing hydrogen sulfide (HS) and/or mercaptans to scavenge HS and/or mercaptans therefrom gives a synergistically better reaction rate and overall scavenging efficiency, i.e. capacity, over the use of the dialdehyde or the nitrogen-containing scavenger used alone, but in the same total amount of the dialdehyde and nitrogen-containing scavenger. The media may include an aqueous phase, a gas phase, a hydrocarbon phase and mixtures of a gas and/or hydrocarbon phase with an aqueous phase.
