The aim of this work is to analyze hydrogen damage and possible prevention in the oil refineries.
Hydrogen damage failures are differentiated into two groups based on two mechanisms:
electrochemical processes (mainly at low temperature, up to ~100oC) arising from acid corrosion or
cathodic protection, and high temperature (between 200 and 900oC) arising from the presence of
hydrogen gas at high pressures. Examples of hydrogen damages and their analysis are given for the
various units of oil refineries.
Key words: hydrogen damage, oil refining industry, prevention.
