Abstract

On peut réduire la formation de sels thermiquement stables d'amines et la corrosion dans un système de traitement aux solvants aux amines en introduisant de la N,N-diéthylhydroxylamine catalysée avec de l'hydroquinone dans le système. La N,N-diéthylhydroxylamine catalysée est efficace dans les plages de température des systèmes de traitement aux amines afin de réduire efficacement la formation de sels thermiquement stables d'amines et d'inhiber la corrosion. La N,N-diéthylhydroxylamine catalysée est efficace dans des proportions dans une plage comprise entre 0,5 et 6 parts environ de N,N-diéthylhydroxylamine par part d'hydroquinone.
