The Analysis of Corrosion Situationabout the Spherical Tanks in the Wet Hydrogen Sulfide Environment

The corrosion situation of sphe~ cal tanks in the wet hydrogen sulfide environment was introduced, and the corrosion mechanisms were also analyzed in del：ail, as well as on influence factors of the low temperature wet hydrogen sulfide corrosion of hydro treating unit in petrochemical installations. Some wet hydrogen sulfide corrosion situations in hydro treating unit were summarized. The concrete reason of stress corrosion cracking and hydrogen knobbing with the actual working condition was obtained. The improvement measures and the matters needing attention in use were proposed
