Zusammenfassung:A method of treating produced water on offshore platforms and onshore facilities is described. The method can be applied to or integrated into other already-installed processes and/or technologies for the treatment of produced water, being characterized by the combined addition of anionic surfactant and cationic polyelectrolyte for the destabilization and flocculation of oily emulsions characteristic of produced water, preliminarily to the separation steps (hydrocyclones and/or flotators). The different points and alternatives of reagent injection combinations are adaptable to equipment and units already in operation.
