Premature failure of tubes during service can be a major cause for the shutdown of refineries and gas processing plants. These failures not only cause a major delay in the production process and considerable financial losses but also initiate emergency repair and maintenance. Amine waste heat reboilers in gas processing plant are critical as they regenerate the amine used for acid gas removal from sales quality gas. Failures in amine heating units can severely affect plant availability. This paper presents two case studies of tube failures related to amine waste heat reboiler units in a gas processing plant. The primary causes and mechanisms involved in the failures are investigated in detail using scanning electron microscopy (SEM) energy dispersive x-ray analysis (EDX) x-ray diffraction (XRD) and electron backscattered diffraction techniques (EBSD) to determine the root cause. Results showed that several mechanisms were involved in tube failures. Pitting stress corrosion cracking oxidation and softening due to spheroidization type corrosion mechanisms are involved in the final failure process. Remedial actions to avoid recurrent failures were also discussed.
