Abstract

A new electrochemical hydrogen probe consisting of a thin layer of deposited nickel was developed for use in laboratory and in field tests. The principle of such a probe is based on the formation of nickel oxyhydroxide (NiOOH) which contains a mobile hydrogen. The probe was used to examine the effect of plastic deformation on hydrogen absorption and the relationship between K^ISCC and hydrogen content, and to monitor hydrogen contents continuously at the carbon dioxide absorption tower and line pipe.
