Streszczenie:
Abstract Glycol systems are widely used in gas processing plants for the removal of contaminants such as moisture from the gas. Since the majority of the piping and vessels in these plants are fabricated from carbon steel, there is a high potential for corrosion. This paper provides a brief overview of some of the major corrosion mechanisms associated with Glycol regeneration unit. In addition, a case study from a triethylene glycol (TEG) regeneration system is also discussed where localized corrosion was noticed in the glycol reboiler and surge vessel.
