Control of formation of heat stable amine salts and of corrosion in an amine solvent treating system is accomplished by introduction of N,N-diethylhydroxylamine catalyzed with hydroquinone into the system. The catalyzed N,N-diethylhydroxylamine is effective at the temperature ranges of amine treating systems to effectively reduce formation of heat stable amine salts and to inhibit corrosion. The catalyzed N N-diethylhydroxylamine is effective in proportions including the range of about 0.5 to about 6 parts N,N-diethylhydroxylamine to 1 part hydroquinone.
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.
