NEW CORROSION MAPPING TECHNOLOGY AT HIGH TEMPERATURE APPLICATION

摘要

Process industries such as oil, gas and petrochemical plants have critical process equipment operating at high temperatures. These equipment require periodic comprehensive integrity assessments for safe and reliable operation. Conventional NDE techniques such as manual ultrasonic are not only slow and subjective, but also often unsuccessful beyond 300°F (150°C). There have been tremendous efforts in the industry to invent suitable new technologies for high temperature application. Hence, comprehensive monitoring of large size equipment operating at higher temperatures remained as a challenging task for decades.In line with this requirement, and in an ongoing effort to deploy new technologies, Uthmaniyah Gas Plant (UGP) in Saudi Aramco, one of the largest gas processing plants in the world, partnered with the Inspection Department in a pilot test program to validate a new corrosion mapping technology at high temperature application up to 500°F. Implementation of this breakthrough technology for the first time in Saudi Aramco at UGP has been successful. This technology also has the capability to scan the process equipment at an operating temperature beyond 725°F (385°C).This paper provides an overview of the importance of a comprehensive assessment to critical process equipment operating at high temperature, ongoing developments to enrich the assessment capabilities and how this technology added value in enhancing the safety and reliability of the operating facility.
