Instrumentation and Control Systems Reliability and Maintenance: Best Practices

Mar 25, 2025

Instrumentation and control systems are critical components to long-term plant safety and reliability. In this article, Rohan examines several maintenance and reliability best practices, including reliability-centered maintenance (RCM) principles, risk assessments, and advanced maintenance strategies. You will also learn how advancements in artificial intelligence (AI) and data analytics are shaping the future of industrial maintenance.

Vessel Overpressure Protection Using System Design – No Relief Valve? You’re Kidding, Right?

Feb 25, 2025

Even though PRDs are the industry standard for overpressure protection, there are cases when an instrumented system design approach can be a good alternative, if it meets ASME Section XIII, Part 13 requirements. Within this article, Phil Henry outlines key considerations, from assessing feasibility to ensuring compliance, and the key questions all owner-users should be asking.

Pipeline Monitoring and Leak Detection: Essential Technologies and Practices

Sep 24, 2024

Due to length and complexity, midstream pipelines are prone to leaks. In this article, Rohan provides a detailed overview of the technologies and practices used in pipeline monitoring and leak detection. In addition, he discusses the importance of leak detection programs for the long-term operation of pipeline infrastructure.

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.

NFPA 70E: Creating an Electrically Safe Work Condition

Dec 19, 2023

Electrical failures can impact safety, production, and overall business operations; the simplest way to create an electrically safe workplace is to implement programs that eliminate the hazard. In this article, the author uses NFPA 70E as a foundation to provide practical recommendations you can implement to create an electrically safe work environment.

Understanding Differential Pressure (DP) Flow Meters: A Comprehensive Overview

Dec 19, 2023

In petrochemical plants, flow meters are designed to enhance efficiency, improve safety, and meet regulatory compliance. Real-time insights regarding fluid movement help to develop sustainable practices and enable precise monitoring for optimal resource management. In this article, you will read about differential pressure, volumetric, and mass flow meters; as well as their working principles, advantages, and installation methods.

Reduction of Nuisance Alarms by Implementing the Alarm Management Lifecycle, A Focus on Rationalization

Oct 24, 2022

We are all familiar with Aesop’s fable, “The Boy Who Cried Wolf.” Similarly, with alarm management, if you hear a false alarm too often, you may miss the opportunity to prevent a dangerous situation or equipment failure. In this article, Melissa Westbrook discusses the dangers of ignoring nuisance alarms and provides actionable insights into developing an alarm rationalization philosophy.
