Effect of Hydroxyethylated Amines on the Corrosion and Hydrogenation of Carbon Steel

Mixtures of hydroxyethylated amines with hydrocarbon radicals C^sub 10^-C^sub 13^ and C^sub 17^-C^sub 20^ containing 2, 5, and 14 ethyleneoxy groups were tested as inhibitors of general carbon dioxide and hydrogen sulfide corrosion and hydrogenation of carbon steel in weakly acidic hydrochloric medi...

Description
Summary:Mixtures of hydroxyethylated amines with hydrocarbon radicals C^sub 10^-C^sub 13^ and C^sub 17^-C^sub 20^ containing 2, 5, and 14 ethyleneoxy groups were tested as inhibitors of general carbon dioxide and hydrogen sulfide corrosion and hydrogenation of carbon steel in weakly acidic hydrochloric media and a simulated highly mineralized stratal water. In electrolytes containing H^sub 2^S or CO^sub 2^ + H^sub 2^S, the protective values of the mixtures were 90 (5 mM HCl) and 96% (50 mM HCl). The hydrogen diffusion through a steel membrane was reduced five times or even suppressed completely by the test compounds.[PUBLICATION ABSTRACT]
