Title (EN) METHODS AND COMPOSITIONS FOR PREVENTION OF FOULING IN CAUSTIC TOWERS
(FR) PROCÉDÉS ET COMPOSITIONS POUR LA PRÉVENTION DE L'ENCRASSEMENT DANS DES TOURS CAUSTIQUES
Abstract:
(EN) Provided are methods and compositions for inhibiting carbonyl based fouling materials of basic wash systems. Said methods comprise contacting the hydrocarbon stream that is or will be subjected to said wash systems with water soluble or water dispersible copolymers. Said copolymers comprise repeat units of ethylenically unsaturated monomers such as acrylic acid with other repeat units such as alkyl acrylates, allyl ethers, ethoxylated allyl repeat units, etc. In other embodiments, a third repeat unit is present and may comprise a hydrophobic moiety such as a styrene repeat unit.
(FR) L'invention concerne des procédés et des compositions pour inhiber l'encrassement à base de carbonyle de matériaux de systèmes de lavage basiques. Lesdits procédés comprennent la mise en contact du flux d'hydrocarbures qui est ou sera soumis auxdits systèmes de lavage avec des copolymères solubles ou dispersibles dans l'eau. Lesdits copolymères comprennent des motifs récurrents de monomères éthyléniquement insaturés, tels que l'acide acrylique, avec d'autres motifs récurrents, tels que des motifs récurrents de type acrylate d'alkyle, allyléther, allyle éthoxylé, etc. Dans d'autres modes de réalisation, une troisième motif récurrent est présent et peut comprendre un fragment hydrophobe, tel qu'un motif récurrent de styrène.
