New Method for Prioritizing Equipment for Inspection and Replacement in HTHA Service

Gerrit Buchheim, Manager of the Pono Division of Becht Engineering, has developed a practical and simple-to-use approach to prioritizing the inspection and replacement of equipment in High Temperature Hydrogen Attack (HTHA) service.  This approach utilizes the existing and accepted “Nelson Curve”, but adapts it to better fit the realized operating conditions at an individual facility, […]

Statistical Analysis of Non-Destructive Examination Data

In 2008, Becht Engineering was awarded a project by the Materials Technology Institute (MTI) to develop an inspection guideline document and software tool for the collection and analysis of inspection data for piping, piping components and pressure vessels. Dr. Eileen Chant , as project manager, collaborated with Bob Sims of Becht, Dr. Mark Stone of […]

Computational Fluid Dynamics (CFD) Confirms Cause of Deaerator Cracking

CFD was used to confirm that poor design of the steam inlet nozzle was the main contributor to deaerator head to shell weld cracking, and confirmed proposed design improvements.  This recent Becht project illustrates one of the causes of deaerator cracking. A through-wall crack had been found at the head-to-shell junction at the steam inlet […]

Updates and New API Standards Addressing Recent Industry Failure/Issues due to Corrosion and Degradation Issues!

In the US and throughout much of the world, pressure equipment for oil refining services is designed according to ASME Codes (possibly augmented by API standards) and the integrity is assured by performing periodic inspection and maintenance according to equipment strategies, which often are developed in accordance with and guidance from API recommended practices and […]

A Novel Nondestructive Technique for Detecting and Sizing Carburization Damage in Heater Tubes

Fired Heaters come in many types and configurations: catalytic reformers, crude heaters, visbreakers, vacuum heaters, coker heaters, etc; and many are prone to carburization damage (i.e. residual carbon diffusing into the tube material, causing damage or even failure). Many refineries today use delayed coking processes to upgrade their crude product. This process includes the use […]

Changing Your Crude Slate?

Changing Your Crude Slate? You Need to Consider More Than Just Naphthenic Acid Corrosion and High Temperature Sulfidation. Refiners are constantly evaluating their crude slates in an effort to maximize profits. It involves a continuous effort in trying to get the most product value from the lowest cost crudes. Generating a $1.00 per barrel margin […]
