Reducing Hydrogen Sulfide Corrosion Formationblueskyadmin
The presence of hydrogen sulfide within high pressure gas streams has continually proven to be a challenge to operators. Among the most problematic issues is the fact that H2S can lead to localized corrosion. Hydrates may occur at low temperatures and high pressures. When sour gas is present, it increases the temperature and pressure at which the formation of hydrates occurs. Effective Hydrogen Sulfide removal methods are critical for preventing the formation of such hydrates and for more effective production. With the right selection of amine scavengers, it is possible to mitigate such corrosion.
Most of the inhibitors currently used in oil production have a nitrogenous nature and can be classified into five broad categories. Those categories include amides, nitrogen quatemaries, nitrogen heterocyclics, polyoxylated amines, and nitrogenous molecule salts. The precise selection of treatment solution may often depend upon the location of treatment. In the case of oil wells, it is generally necessary to inject inhibitors directly into the borewell for the purposes of increasing flow lines.
