About Us

Brimstone STS Limited is a Colorado-based corporation that offers unique services and products for field testing and evaluation of sulfur-related processes in the refining, gas processing, and chemical industries. The various field testing services available through Brimstone range from onsite analytical testing of individual process gas streams to full process performance evaluations of sulfur processing units.


Brimstone provides analytical testing equipment that allows our clients to conduct their own sulfur testing. Complete Gas Chromatography systems can be custom built for measuring sulfur compounds in process gas streams. Also, the 941 LS Liquid Sulfur Analyzer measures H2S in liquid sulfur product. Finally, custom sampling tools and equipment allow safe and reliable sampling and storage of delicate sulfur-containing process gas and LPG samples.

Testing Services

Brimstone has built a reputation for solving difficult analytical problems and providing solutions to critical engineering and environmental compliance problems. Testing services available through Brimstone range from onsite analytical testing of process gas streams, such as trace sulfur compounds in fuel gas, to full process performance evaluations for amine, Claus sulfur recovery, and tail gas treating units.


Our workshops present the basics of sulfur recovery and gas treating with the goal of providing your operations and engineering staff with practical information that helps them in their efforts to safely and efficiently meet their operating goals. Our highly-interactive courses contain Q&A and discussion with our outstanding instructional staff. Brimstone offers this training in the form of a highly-effective four-day, in-house workshop tailored to your facility and operation.


Our highly successful Vail Sulfur Symposium has become the premier conference for those interested in exchanging ideas relating to sulfur recovery. The focus of the Vail Sulfur Symposium, held every September, includes new and existing technologies, products and services for operation of amine, Claus sulfur recovery, and tail gas treating processes. This spring we will host our third annual Vienna Symposium in May and our first ever Middle Eastern Symposium in Abu Dhabi in June.

“The 2015 Vienna Brimstone Sulfur Recovery Symposium will be remembered by many for the full participation and detailed open floor discussions and round table sessions when attendees, including many sulphur industry experts, shared information and industry experiences in the quest to improve the efficiency and safety of sulphur industry operations and to find solutions to various operating problems and anomalies. The programme for this year’s symposium followed the usual format combining a selection of presentations on a wide variety of topics interspersed with open Q&A, workshop and round table sessions.”
