Abstract: A method is provided for reducing the amount of hydrogen sulfide and organic sulfides present in streams, such as natural gas streams, by scrubbing the stream with a composition containing (i) an aqueous phase containing a reaction product resulting from the reaction between an aldehyde, such as formaldehyde, and a first amine, such as monoethanolamine or aminoethylpiperazine, and (ii) an organic phase containing at least a second amine, such as butylamine, pentylamine or hexylamine, to produce: (1) a stream having a diminished amount of sulfide contaminants and (2) a sulfided reaction product, such as trithiane. The sulfided reaction product is solubilized into the organic phase (which precludes the formation of solids), and this resulting sulfided reaction product-containing organic phase is separated from the aqueous phase. The sulfided reaction product-containing organic phase may be used as a corrosion inhibitor, and the composition has reduced foaming characteristics during the scrubbing step.
