Abstract:
1. A method for reducing noxious sulfur species in a pipeline transmitting a bi-phasic fluid comprising the step of: administering, to a liquid-liquid bi-phasic fluid being transmitted through a pipeline, an effective amount of a composition comprising: where the bi-phasic fluid includes an aqueous phase, an organic or oil phase and noxious sulfur species are found in both phases, where the water soluble sulfur scavenger component is adapted to partition into the aqueous phase, where the oil soluble sulfur scavenger component is adapted to partition into the organic or oil phase and into organic layers that form and build up on interior surfaces of the pipeline and where the effective amount is sufficient to separately and simultaneously reduce concentrations of noxious species in both phases and in the layers that form and build up on interior surfaces of the pipeline and where the emulsified oil soluble sulfur scavenger reduces formation of the layers and build up on interior surfaces of the pipeline.
