Title
(EN) CONTAMINANT REMEDIATION WITH FUNCTIONALIZED (METH)ACRYLIC POLYMER OR COPOLYMER MACROPARTICULATES AND SYSTEMS RELATED THERETO
(FR) ÉLIMINATION DES CONTAMINANTS À L'AIDE DE MACROPARTICULES D'UN POLYMÈRE OU D'UN COPOLYMÈRE (MÉTH)ACRYLIQUE FONCTIONNALISÉ, ET SYSTÈMES ASSOCIÉS
Abstract
(EN)
Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile. An internal cavity may be formed when functionalizing the (meth)acrylic polymer or copolymer in the presence of a hindered amine base. When appropriately functionalized, the macroparticulates may be used to sequester a contaminant from a substance in need of contaminant remediation, such as produced water or flowback water from a wellbore job site. Reclaimed water obtained from the macroparticulates may be utilized to form a treatment fluid. The macroparticulates may be located within a continuous flow line, particularly within a removable cartridge, to promote removal of at least one contaminant from a substance in need of contaminant remediation. The substance in need of contaminant remediation and/or the macroparticulates may be visually or spectroscopically interrogated to determine whether the macroparticulates have become saturated with contaminant.
(FR)
L'invention concerne des macroparticules qui peuvent être formées par un auto-assemblage au moins partiel par réaction d'un polymère ou d'un copolymère (méth)acrylique contenant un époxyde avec un composé portant un nucléophile azoté. Une cavité interne peut être formée lors de la fonctionnalisation du polymère ou du copolymère (méth)acrylique en présence d'une base amine à encombrement stérique. Lorsqu'elles sont convenablement fonctionnalisées, les macroparticules peuvent être utilisées pour isoler un contaminant provenant d'une substance ayant besoin d'une élimination des contaminants, telle que l'eau produite ou l'eau de reflux provenant d'un chantier de puits de forage. L'eau régénérée obtenue à partir des macroparticules peut être utilisée pour former un fluide de traitement. Les macroparticules peuvent être situées à l'intérieur d'une trajectoire continue, en particulier à l'intérieur d'une cartouche amovible, afin de favoriser l'enlèvement d'au moins un contaminant à partir d'une substance ayant besoin d'une élimination des contaminants. La substance ayant besoin d'une élimination des contaminants et/ou les macroparticules peuvent être interrogées à l'œil nu ou par spectroscopie, afin de déterminer si les macroparticules se sont ou non saturées en contaminant.
