ABSTRACT:
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.
