Identifying Worker Density Constraints During Process Outages

How to Identify a Hidden Productivity Constraint in Your Process Outage Plans and Schedules During inspections and maintenance outages, labor cost is usually a significant expense. In order to meet the required cost and duration goals, worker efficiency is critical. As part of the job plans and schedule creation, a planning team was able to […]

Critical Mass Duration for Process Outages

Avoid This Surprise When Determining How Long Your Next Process Outage Will Take Continuous processing or manufacturing facilities will occasionally require planned outages to primarily address reliability or maintenance issues.  Due to the high cost of these outages (opportunity and real), careful planning and scheduling practices are used to come up with detailed execution plans […]

Why Doesn’t a Great Maintenance Process Equal Great Results? (Part 2)

In Part 1 we observed that some of the best results come from organizations with poor maintenance work processes and some organizations with a great work process have poor results.  It was also noted that the maintenance work process itself only accounts for 10% to 20% of the total maintenance value.  In Part 2 we […]

Why Doesn’t a Great Maintenance Process Equal Great Results?

Becht made an interesting observation on maintenance processes after consulting in several facilities — Some of the best results come from organizations with poor maintenance work processes and some organizations with a great work process have poor results. Why is this? The reason is that maintenance results or maintenance value is dependent on more than […]

Improving Burner Design And Operation With CFD Modeling

by Dave Dewees & Zumao Chen Computational fluid dynamics (CFD) modeling can be used as an efficient and low-cost alternative to improve the design and operation of a new burner. There are many factors that affect the performance of burners in a charge heater in a refinery. The burner must maintain a certain heat flux […]

Improving Fixed Bed Naphtha Reformer Catalyst Regeneration

Background Refiners have been reforming naphtha to improve its octane or to produce aromatic chemicals since the 1930s. Initially the desired chemical reactions were achieved in Thermal Reformers without the use of catalyst by simply heating the naphtha to about 540°C (1000°F) to “crack” non-aromatics out of the naphtha boiling range. This was effective but […]

Origins and Fates of Chlorides in Hydroprocessing Units – Part 3: Managing the Chlorides

The first two articles of this series provided a methodical approach to identifying a chloride problem in a hydroprocessing unit, determining the size of the problem, and narrowing it down to a likely source or sources.  This final article addresses approaches to dealing with various sources. Step 4 – Managing the Chlorides Now that you […]

Origins and Fates of Chlorides in Hydroprocessing Units – Part 2: Magnitude and Source(s) the Problem

The first article of this series introduced the symptoms of a chloride problem in a hydroprocessing unit.  In this article, we will explore how to interpret the symptoms by determining how much chloride-containing material we are looking for and identifying the possible or likely source(s) for this amount of material, embodied in Steps 2 and […]
