COMPOSITION AND METHOD FOR SCAVENGING SULFIDES AND MERCAPTANS

This invention relates to a composition comprising 1.) a metal carboxylate, wherein the metal M is selected from the group consisting of Ag, Cn, Hg, Pb, Sn, Ni, Co, Ca, Fe, Zn and Mn, those metals being present as ions in a +2 or +3 charge state, and wherein the carboxylate anion is derived from a hydrocarbyl monocarboxylic acid having 5 to 20 carbon atoms, or a mixture of such acids, 2.) a solvent selected from the group consisting of water, glycol ethers having from 4 to 15 carbon atoms, alkyl alcohols having from 1 to 10 carbons, and aromatic hydrocarbon solvents having from 6 to 30 carbons, and 3.) an emulsion breaker which is a polymeric nonionic surfactant.
