The present invention relates to a hydrogen sulfide scavenging additive composition for scavenging sulfur-containing compounds comprising hydrogen sulfide and mercaptans, in particular for scavenging hydrogen sulfide from hydrocarbons, wherein the additive composition comprises a significantly reduced amount of nitrogen-based sulfides Hydrogen scavenger, and the required amount of the additive composition is also significantly reduced, and wherein the additive composition is capable of scavenging sulfur-containing compounds not only at room temperature, but also at higher temperatures, and contains at least the following substances A combination of: (A) at least one nitrogen-based hydrogen sulfide scavenger; (B) at least one aliphatic tertiary amine, wherein the nitrogen-based hydrogen sulfide scavenger comprises a triazine-based hydrogen sulfide scavenger. In one embodiment, the present invention also relates to a method of scavenging hydrogen sulfide from hydrocarbons, and in another embodiment, the present invention relates to a method of scavenging hydrogen sulfide from hydrocarbons using the additive composition of the present invention. In yet another embodiment, the present invention relates to a composition for scavenging hydrogen sulfide from hydrocarbons, the composition comprising (i) a hydrocarbon; and (ii) an additive composition for hydrogen sulfide scavenging. |
