Technical Paper: Convection Section Failure Analysis and Fitness-for-Service Assessment for an Ammonia Plant

A brittle fracture failure of several HK-40 tubes occurred in the convection section of an ammonia plant feed gas heater. A failure analysis and API 579 Fitness-for-Service assessment determined the mode of failure and remaining life of the HK-40 tubes. This information provided the operator with a sound basis for continued operation until long-term repairs and system improvements could be implemented.

Technical Paper: Stress Corrosion Cracking in Syngas Plants that may be Missed by Risk-Based Inspection

Stress corrosion cracking continues to be a problem in aging plants and must be considered when completing a risk-based inspection program or setting integrity operating windows. Case studies on chloride SCC below 60°C (140°F), chloride SCC under support plates, pure water SCC of Inconel 600 and polythionic SCC of 304 are covered in this paper. In each case, these damage processes could be easily missed in an RBI assessment.

Published Article: Compressor Dovetail Remnant Life Assessment

This case study of a compressor dovetail remnant life assessment demonstrates the implications of small aerodynamic loads. It also explains the use of computational fluid dynamics and finite element analysis stress modeling to obtain the remnant life of the compressor blades.
