The invention discloses a scavenger composition for use in eliminating and/or reducing hydrogen sulphide and/or mercaptans in a fluid, particularly for reducing or eliminating hydrogen sulphide from gases and liquids, including gaseous and liquid hydrocarbons, and sewer gases, and more especially from natural gas and liquid hydrocarbon streams. The composition makes use of a primary scavenging agent and a scavenging accelerator additive, which also acts as a precipitation inhibitor. The composition involves the use of a 1,3-dioxolane alkyl, alkenyl and/or hydroxyl derivative as primary scavenging agent, and accelerator additives based on ketones, including α-diketones, cyclic ketones, saturated ketones and/or α-unsaturated ketones. |
