Managing Refractory Degradation and Hotspots in Cold-Walled Equipment

Aug 26, 2024

Refractory linings are used to protect pressure vessels and piping components from hot process conditions but can degrade over time, leading to hotspots, creep damage, and potential failure. In this article, the authors discuss the benefits of conducting periodic inspection programs to manage refractory degradation and share an example to highlight the importance of detecting permanent material damage caused by creep or creep-fatigue.

Advanced Analysis of Equipment Repairs and Alterations

Jul 30, 2024

Maintenance programs require a significant investment of time, energy, and money to keep facilities and equipment operating safely and reliably. Despite these efforts, there will always be a need for repairs, replacements, or alterations. In this article, the authors use a variety of case studies to discuss how advanced analysis techniques can support several post-construction activities. They offer insight into how to evaluate weld repair plans and post-weld heat treatments, validate rerate conditions, and ensure structural integrity.

Are There Gaps in Your Pressure Relief Program?

Jul 30, 2024

Pressure relieving systems serve as the last line of defense against the dangers of overpressures in our facilities, but this protection can be jeopardized by poor maintenance and degradation. Active safeguarding of this protective system is crucial to preventing catastrophe. While the requirement for pressure relief is rooted in the ASME code, it is the US CFR 29 1010.119 [1] that requires the proper documentation of relief system design and design bases.

Reuse Practices, Midstream Engineering Practices, and Other Additions to The Equity Engineering Practices

Jul 30, 2024

Corporate standards or engineering best practices are help owner-users manage equipment and facilities by promoting safety, managing risk, improving reliability, capturing corporate memory, and transferring knowledge. In this article, Joel highlights two new collections that were recently added to the Equity Engineering Practices (EEPs) to support clients in the midstream and renewable energy industries, plus he provides a sneak peek into some of the innovative tools currently in development. The EEPs are the gold standard for all your engineering standards needs.

Understanding Operating Limits on Reactor Internals

Jun 24, 2024

Hydroprocessing equipment is an important component that helps increase production at refineries. However, during regular operations, the efficiency and run life of these reactors can be compromised by build up on the catalyst surface, leading to costly shutdowns or reduced production. In this article, Adam and Matt discuss how monitoring bed support differential pressure can maximize runtime. They use a recent case study to demonstrate how their analysis of the catalyst bed effectively delayed a shutdown at refinery.

Temperature Measurement Hydrocracking Reactors

Jun 24, 2024

As more refineries begin to process biofuels, it is important to establish a consistent and accurate temperature measurement program to ensure the hydrocrackers are capable co-processing the new feedstock safely and reliably. In this article, Rohan and Ahmed review the fundamentals of temperature measuring devices and discuss key maintenance and reliability techniques that you can apply to prevent unplanned shutdowns.

Enhancing Electrical Infrastructure: The Importance of Electrical Safety and Reliability Audits

May 28, 2024

In today’s rapidly evolving technological landscape, ensuring the safety and reliability of electrical systems is paramount. Electrical failures can lead

Case Study: Diagnosing the Root Cause for High Vibrations on a Vertical Pump

May 28, 2024

Determining the cause of a change in machinery condition can be a difficult task, and vibration analysis is a valuable

Advancements in Risk-Based Inspection Strategies for Ammonia Storage Tanks

Apr 30, 2024

Developing a repeatable, in-service inspection strategy for ammonia storage tanks is difficult; however, it will help improve operational reliability and minimize the probability of failure from several damage mechanisms, including ammonia stress corrosion cracking (SCC). In this article, the authors discuss Equity’s multi-disciplinary approach to navigate the challenges of these high-consequence ammonia storage tanks. Read how we integrate risk-based inspection (RBI), fitness-for-service (FFS), and materials and corrosion expertise to provide a comprehensive and practical inspection strategy.

Materials & Corrosion Considerations for Ammonia, Urea, Nitric Acid, & UAN Units

Apr 30, 2024

Over the past 20 years, the fertilizer industry has experienced several metallurgical and operational advancements for process equipment. In this article, Raj and Phil discuss the ongoing challenge of damage mechanisms and corrosion-related issues in fertilizer plants and highlight the critical role of materials selection and process monitoring in managing equipment degradation rates. Read more and learn how to achieve long-term equipment reliability and maintain a robust mechanical integrity program through the routine collaboration between materials/corrosion, mechanical, and process engineering subject matter experts and inspection specialists.
