Title (EN) DECREASED PRESENCE OF AMINE-DERIVED CONTAMINANTS IN- AND/OR DEGRADATION OF AMINE SOLVENT SOLUTIONS
(FR) DIMINUTION DE LA PRÉSENCE DE CONTAMINANTS ISSUS D'AMINE DANS DES SOLUTIONS DE SOLVANT À BASE D'AMINE ET/OU DE LA DÉGRADATION DE CELLES-CI
Abstract:
(EN) An amine solvent solution that is useful in absorbing acid gases from a liquid or gas feed stream may have an amine additive added thereto. Additionally or alternatively, the amine additive may be added to a liquid or gas feed stream. The addition of the amine additive decreases the presence of amine-derived contaminants and/or degradation of amine in the amine solvent solution. As such, the amine solvent solution is available for effective reuse in treating the liquid or gas feed stream and there may be a decrease in the corrosion within an amine treating system.
(FR) Une solution de solvant à base d'amine qui est utile dans l'absorption de gaz acides à partir d'un écoulement de charge liquide ou gazeuse peut avoir un additif amine ajouté à celui-ci. De plus ou en variante, l'additif amine peut être ajouté à un écoulement de charge liquide ou gazeuse. L'ajout de l'additif amine diminue la présence de contaminants issus d'amine et/ou la dégradation d'une amine dans la solution de solvant à base d'amine. En tant que telle, la solution de solvant à base d'amine est disponible pour une réutilisation efficace dans le traitement de la charge liquide ou gazeuse et il peut y avoir une diminution de la corrosion à l'intérieur d'un système de traitement d'amine.
