During the last 40 years the sulfur recovery industry has successfully worked through challenges such as tail gas treating, ammonia destruction, debottlenecking, and turndown operations. One by one, operators and designers of sulfur recovery processes have solved these problems and now we face our currently most important task: making these units operate more trouble-free and with longer run times. Stated another way, how do we increase onstream efficiency and reduce maintenance costs? Even more simply, how do we improve reliability?

Based on the subject matter and discussions in our annual Sulfur Symposium conferences as well as in our training classes, we recognize that more and more time is being spent on reliability and maintenance topics. Plant reliability has always been part of our jobs, but it has now moved to the forefront and become the single most important area of interest to most plants. To address this, Brimstone has developed the first open classroom course focusing on Sulfur Recovery Reliability and Maintenance. The goal of this course is to help plant operators lengthen run time between scheduled turnarounds, and to minimize the frequency and severity of unplanned repair outages.

This first ever course of this type will take place during the week of May 7th. It will be of value to any plant staff involved in operation and maintenance of sulfur recovery and amine treating units: personnel from operations, planning, project engineering, and maintenance. Because of the very large amount of material to be covered, this course will last four and a half days. This inaugural course will cover Claus sulfur recovery, tail gas treating, amine treating and sour water stripping. It will focus on reliability and maintenance problem areas and how to best manage them.

A course such as this is possible due to the extensive hands-on experience of our outstanding instructional staff, many of whom have worked as Subject Matter Experts for their respective companies. (Click to view our instructional staff.) Their vast experience allows informative back-and-forth exchanges on a wide range of sulfur recovery topics. The Reliability and Maintenance course will be led by two of Brimstone’s excellent instructional staff: Shelley Hittel and Elmo Nasato.

For the first time, Brimstone is offering our training courses both as live, in-person classroom sessions and in virtual form via Zoom.


Course Instructors

During the last 20 years, Shelley Hittel has worked as a facility and process engineer at a number of sour gas plants in western Alberta. She works closely with plant operations and maintenance teams to optimize and troubleshoot processes as well as coordinating and supporting maintenance repairs and plant turnarounds. Shelley holds B.E. and M.Sc. degrees in Chemical Engineering from the University of Saskatchewan and is a registered P.Eng. in the province of Alberta. She is also a member of the Amine Best Practices Group.


Elmo Nasato is a senior process engineering consultant specializing in sulfur recovery, amine treating and sour water processing. He has over 30 years’ experience in the sulfur recovery industry including experience with design, retrofit, start-up and optimization of sulfur recovery units, sulfur handling units, amine units, sour water stripper units, and tail gas cleanup units. On-site field activities have included support of construction activities, turnaround assistance and operator training.
