Beschreibung
Zusammenfassung:A process for simultaneously dissolving iron sulphide and killing or inhibiting bacteria comprising the steps of continuously adding or shot dosing to a hydrocarbon-containing system, an aqueous fluid comprising a formulation comprising tris(hydroxymethyl) phosphine or tetrakis (hydroxymethyl) phosphonium salt. L'invention concerne un procédé de dissolution de sulfure de fer et de destruction ou d'inhibition simultanée de bactéries, comprenant les étapes consistant à ajouter en continu ou à doser par intermittence, à un système contenant des hydrocarbures, un fluide aqueux comprenant une formulation contenant de la tris(hydroxyméthyl)-phosphine ou un sel de tétrakis(hydroxyméthyl)-phosphonium.
