CCR Naphtha Reforming Unit Turnarounds II Rx Internals Inspection w/ Upflow Centerpipe

This article is the second in a series on Rx Internals Inspection but with focus on equipment underneath the coverdeck.  Although, I’d like to touch on a broader TA topic that merits reinforcement with contractors and refinery personnel alike – protecting gaskets and seating surfaces. Turnarounds bring a level of activity with the movement of […]

CCR Naphtha Reforming: Radial Flow Reactors Catalyst Bed Pressure Explained – Avoiding Rx Internals Damage

Introduction: Before continuing with CCR Naphtha Reforming Turnarounds it seemed appropriate to explain the cause and effects of unchecked thermal cycles and high catalyst bed pressure. This information is vital to understanding how to mitigate Rx internals damage and improves the ability of operators and engineers to evaluate unit equipment and catalyst performance more effectively.  […]

CCR Naphtha Reforming Refinery Unit Turnarounds — Rx Internals Inspection w/ Upflow Centerpipe

Introduction Scheduled turnarounds (TA’s) on CCR naphtha reforming units are infrequent with customers targeting every 5+ years, and frequently hitting their targets.  That leaves little opportunity for many engineers and operators to participate in these events. So, it seemed appropriate to generate an article that shares what I’ve experienced during my career, while keeping each […]

Preventing Nickel Carbonyl Formation during Hydroprocessing Unit Shutdowns

The potential formation of nickel carbonyl is a hazard for all hydroprocessing units – both hydrocrackers and hydrotreaters. Fortunately, there have not been a lot of incidents in the refining industry related to nickel carbonyl, but there have been fatalities due to nickel carbonyl exposure. This blog will cover the risks of nickel carbonyl exposure, […]

The Best Path To Maintenance Cost Reduction

While most organizations acknowledge a link between maintenance and reliability, the maintenance and reliability departments are often held within separate organizations at both site and corporate levels.  They typically have separate goals and work separately to achieve these goals.  One of the key measurements of the maintenance department is the maintenance budget while a key […]

Controlling Your Maintenance Turnaround Scope, from Kick-Off to Closeout

In the November 2021 online edition of “The Chemical Engineer” magazine, Gordon discusses the need to keep turnaround scope to a manageable size and avoid excessive scope growth. He points out that although many teams focus on the valuable activity of challenging the scope (i.e. challenging whether individual scope items need to be included) just prior to scope […]
