Corrosion by Sulphur and Hydrogen Sulphide

Author(s):
Abstract:
Sulphur readily corrodes carbon steel. The corrosion product, Fes, a pyrophoric material, is potentially dangerous. Corrosion can be mitigated by ensuring that a barrier, a lime slurry, exists between the steel and the sulphur. Recent works shows that a lime/zinc hydroxide barrier should be more effective. Additionally disulphide have been applied to remove sulphur deposits from the walls of the tubing string or in surface lines. It should be noted that a combination of both acidity generation and corrosion can lead to a build-up of H2S in a sulphur shipment. Under the right conditions, H2S can also directly corrodes steel.
