Mr. / Ms. Sulfur™ Club

Membership in the "Mr./Ms. SULFUR™ Club" is an acknowledgment of "EXCEPTIONAL KNOWLEDGE AND EXPERIENCE with extensive contributions to the sulfur/amine process industry".

Membership to the "Mr./Ms. Sulfur™ Club" is given to those people who are peer-recognized for demonstrating exceptional knowledge and experience in the fields of sulfur recovery and amine treating. They are also distinguished for going above and beyond by publicly contributing to the betterment of the industry. Often, this involves participation in industry committees along with publication and presentation of important technical papers that inform the industry as a whole.

During the last six years, "Mr./Ms. Sulfur™ Club" membership has been awarded to 19 members of our industry. These recipients include experts from operating companies, vendor/supply companies, and academia. Along with the conventional awarded memberships, there are also honorary and special achievement recipients. Typically, one or two memberships are awarded each year, chosen through nomination and voting by the existing club members.

The "Mr./Ms. Sulfur™ Club" is the brainchild of Philip Oberbroeckling of Houston Refining.  After being nicknamed “Mr. Sulfur” by the Sulfur Complex Modernization/Expansion Project Team at his refinery in 2011, Phil had the idea to share this concept of industry recognition and expand it beyond the borders of his plant into the sulfur/amine industry as a whole.

As Club President, he developed the club organization and voting policies and has conducted the awards ceremony every year since its beginning in 2012 at the Brimstone Vail Sulfur Symposium. Philip also created the iconic trophy “Mr. Sulfur Hat”, given to every new member at each annual awards ceremony. Although the awarding of membership originated at the Brimstone Vail Sulfur Symposium, it is not limited to attendees of that conference. Nor is it limited to those from North America: we expect to reach out and begin nominating members on a global basis in the near future.

When considering potential club members, an emphasis is given to recent contributions coupled with career-long achievements.  An example would be the tremendous recent efforts made by many people to the API/ANSI 565 Standard Development on Thermal Reactors.
