Title (EN) ACRYLAMIDE REMOVAL FROM AQUEOUS FLUID BODIES
(FR) ÉLIMINATION D'ACRYLAMIDE À PARTIR DE MASSES DE FLUIDE AQUEUX
Abstract:
(EN) This invention is a method for removing acrylamide from large bodies of water or from other acrylamide-containing aqueous fluids. The acrylamide- containing water or aqueous fluid is treated with a peroxygen that is preferably persulfate, hydrogen peroxide or activated peracetic acid. The invention is particularly useful for treatment of acrylamide-containing aqueous fluids associated with oil and gas drilling and recovery applications and includes aqueous well treatment fluid compositions comprising an acrylamide-derived polymer and a peroxygen compound capable of generating free radicals, useful in slickwater well treatment applications.
(FR) Cette invention porte sur un procédé pour l'élimination d'acrylamide à partir de masses importantes d'eau ou d'autres fluides aqueux contenant de l'acrylamide. L'eau ou le fluide aqueux contenant de l'acrylamide est traité par un composé peroxygéné qui est de préférence un persulfate, du peroxyde d'hydrogène ou de l'acide peracétique activé. L'invention est particulièrement utile pour le traitement de fluides aqueux contenant de l'acrylamide associés à des applications de forage et de récupération d'huile et de gaz, et comprend des compositions fluides aqueuses de traitement de puits renfermant un polymère issu de l'acrylamide et un composé peroxygéné apte à produire des radicaux libres, utiles dans des applications de traitement de puits d'eau de nappe.
