Title (EN) PARAFFIN SUPPRESSANT COMPOSITIONS AND METHODS
(FR) COMPOSITIONS DE SUPPRESSION DE PARAFFINE ET PROCÉDÉS
Abstract:
(EN) Disclosed herein are paraffin suppressant compositions, and methods of making and using them. The compositions comprise a paraffin inhibitor, a hydrocarbon-soluble hydrotrope equivalent, and optionally one or more additional paraffin dispersants. When added to hydrocarbon media such as crude oils to form crude oil compositions, the suppressant compositions inhibit the precipitation of paraffin waxes in the crude oil compositions. The suppressant compositions, added to hydrocarbon media such as hydrocarbon solvents or crude oils, exhibit reduced precipitation, gelling, and/or crystallization of paraffin inhibitor from the hydrocarbon media, when the media are subjected to sustained temperatures between 4C and -60C.
(FR) L'invention concerne des compositions de suppression de paraffine ainsi que des procédés de préparation et d'utilisation de celles-ci. Ces compositions comprennent un inhibiteur de paraffine, un équivalent hydrotropique soluble dans les hydrocarbures, et éventuellement un ou plusieurs dispersants de paraffine supplémentaires. Lorsqu'elles sont ajoutées à des milieux hydrocarbonés tels que les pétroles bruts pour former des compositions de pétroles bruts, ces compositions de suppression inhibent la précipitation de cires de paraffine dans les compositions de pétroles bruts. Ces compositions de suppression, ajoutées à des milieux hydrocarbonés tels que les solvants hydrocarbonés ou les pétroles bruts, permettent d'obtenir une précipitation, une gélification et/ou une cristallisation réduite de l'inhibiteur de paraffine dans les milieux hydrocarbonés, lorsque ces milieux sont exposés à des températures prolongées comprises entre 4 °C et -60 °C.
