Brimstone Sulfur Symposium Details – Vail

September 12th through 16th, 2022

Conference registration begins Wednesday, June 15th at 07:30 PDT.

For a number of operating companies, Brimstone uses appointed “Seat Block Coordinators” who approve registrations for attendees from their companies. The June 15th date for registration does not apply to attendees from operating companies. Attendees from operating companies have until Wednesday, July 13th to register. If you work for one of the following companies, please contact your Company Seat Block Coordinator before attempting to register:

The scheduling of live conferences and meetings has been very difficult during the last two years, but we are hopeful that with the continued improvements in the pandemic situation, we will be able to return to our Brimstone Sulfur Symposium home in Vail, Colorado this September and recommence our live, in­person conferences. We’re proud to say that this 2022 meeting will be our 29th straight year. We must express our sincerest gratitude to our loyal friends who stuck with us the last two years and attended the “Virtual Vail” versions of our Sulfur Recovery Symposium. We look forward to seeing everyone in person again this fall. It must be said, however, that it is still possible that public health concerns may force us to modify our plans for an in-person meeting and, as a worst-case, we may be forced to conduct a third virtual symposium instead. We will keep everyone updated about any changes in our plans for the conference, both through e-mails and through our website.

The symposium takes the form of organized presentations and panel discussions by industry experts, operating companies, and suppliers of products and services.  In addition to the presentations and panels, each daily session will include one or more open-floor question and answer periods.  These standalone Q&A sessions have proven to be a very important part of the symposium.

In addition to the papers mentioned above, annual presentations covering important subjects such as safety and regulatory issues along with plant startups and shutdowns are given each year. Alberta Sulphur Research Limited, the premier research organization for sulfur processing, presents one or more technical papers each year at the Brimstone Sulfur Symposium. Similarly, the highly respected Amine Best Practices Group provides a technical paper and a dedicated Q&A session.  For a listing of recent presentations, see below. We limit the maximum number of attendees to around 90 registrants. We find that keeping the symposium to a modest size is key to encouraging participation.

Location and Transportation

The symposium will be held at the Sonnenalp Hotel of Vail. The town of Vail is approximately 120 miles west of the Denver International Airport. Two different shuttle van services between the Denver airport and Vail are available: Peak 1 Express at https://www.mountainshuttle.com, phone 855 467 3251, and Epic Mountain Express at https://www.epicmountainexpress.com, phone 970 754 7433. Because there are so many Vail Village restaurants, shops, and services within easy walking distance of the Sonnenalp, many attendees don’t bother with a rental car.


Registration Fee

The symposium registration fee ($1,950.00 USD) covers all symposium materials and lunches. Attendees are responsible for their own hotel accommodations, breakfasts, dinners (except Wednesday evening, which is included) and transportation. The symposium is held in the Sonnenalp Resort Hotel, and discounted room rates (approximately $210 per night, plus taxes and fees) have been arranged for our attendees.  Spouses are always welcome at our conferences, but in order to keep costs under control, we will impose an additional fee for spouses who plan to attend the lunches or the Wednesday dinner. The cost for an additional seat at the three lunches is $85 and the cost for an extra seat at the Wednesday dinner will be $85.

The registration fee will be refunded in full if a cancellation notice is received on or before August 10th. After that date, if you find that you cannot attend but would like to send someone else from your company in your place, just have them register and send us an e-mail (or give us a call) and let us know. Please note that submission of a registration form signifies a commitment to pay the conference registration fee.

In the event that the 2022 Sulfur Symposium must be held again as a virtual meeting, the registration fee will be $500 and anyone who has paid the full conference fee of $1,950 will be refunded the balance.

Vail Open Golf Tournament

For several years now, some attendees of the Vail Sulfur Symposium arrive early and enjoy a little R & R in the mountains at one of the many excellent golf courses in the area. Join us on Monday morning for a fun golf event at the Eagle Ranch Golf Club. Foursomes play in a Best Ball format with long drive, closest to the pin, and other contests. There are numerous prizes each year donated by many of our attending vendor companies. Skill levels range from scratch golfers to absolute beginners, so don’t be afraid to come out and give it a try. (Trust us, no matter how bad you are, there will be someone worse.) Spouses are more than welcome. For more details, watch for an e-mail flyer and/or contact our non-Athletic Director, Mike Anderson at (909) 597-3249 or [email protected]. Come join us and have some extracurricular fun!
