Sour Gas Corrosion Inhibitor (WESTCOR)
Sour gas is natural gas or any other gas containing significant amounts of hydrogen sulfide (H2S). The detrimental effects as a result of sour service can range from small pinhole leaks to catastrophic failure in pipelines owing to a number of phenomena as a result of the sour gas environment, namely: stress corrosion cracking, sulphide stress corrosion cracking, hydrogen-induced cracking, hydrogen embrittlement and exfoliation, and sulphide-oriented hydrogen-induced cracking.
Mitigation and/or control of cracking in sour gas pipelines can be approached in a number of ways, namely steel manufacturing control, materials and fabrication processes, controlling the environment, and isolating the components from the sour environment.
Our Company provides corrosion inhibitors and onsite batching operation to control internal corrosion related to hydrogen sulfide and carbon dioxide. We have successful cases to deal with the world most severe sour gas gathering system with H2S level 10-15% and CO2 level 8-12%.
