What Sulfur Operations Support does
Sulfur Operations Support, Inc. (SOS) is a privately held specialty equipment manufacturer and engineering services provider serving the sulfur recovery segment of the global oil and gas industry. Founded in 1982 as Advanced Petrogas System in Sealy, Texas, the company relocated to Ocean Springs, Mississippi in 2005 and pioneered the SulTrap™ in 1988 — an above-ground float trap that replaces the conventional underground seal legs used in Claus Sulfur Recovery Units (SRUs). Headquartered on the Mississippi Gulf Coast with 11–50 employees, SOS sells a portfolio of patented and patent-pending equipment built to ASME, CRN, and PED standards under ISO 9001:2015 certification, including Sulview Sightport, Collection Header, Multi-Point SO2 Injection, Pressure Surge Relief Device (PSRD), Sul-Tower, and Sul-Clean.
The company's product architecture centers on replacing hazardous, maintenance-intensive underground sulfur handling infrastructure with modular above-ground components designed for in-place servicing. SulTrap™ alone has been deployed in over 2,400–3,000 cumulative units worldwide across five major geographic regions since 1988, with claimed advantages including five-minute in-place strainer cleaning, elimination of crane-dependent maintenance outages, and avoidance of production curtailment. Complementary products target Claus unit capacity expansion (Multi-Point SO2 Injection, Sul-Tower), sulfur degassing and H2S removal (Sul-Clean), pit replacement (Collection Header), and pressure relief (PSRD). SOS complements equipment sales with engineering consulting, on-site inspection/troubleshooting, and operator start-up training services, leveraging what the company describes as over 100 years of collective sulfur recovery industry experience on its team.
SOS operates a direct enterprise field-sales model with no disclosed channel partners, resellers, or institutional investors. Its named customer base includes major integrated and national oil and gas companies such as ExxonMobil and Qatar Gas, with the company explicitly stating that customers return repeatedly for new plants and retrofits. Revenue figures are not publicly disclosed, the company has no reported funding rounds or parent entity, and ownership remains entirely private.

Products and services
- SulTrap™ Patented float trap designed to replace conventional underground seal legs in Claus Sulfur Recovery Units; above-ground system that separates liquid sulfur from acid gas, with internal basket strainer cleanable in five minutes and optional internal flow meter.
- Sulview Sightport Patent-pending sightport that provides a constant unobstructed view of sulfur flow content inside a SulTrap™, with steam coil to prevent fogging, glass windows rated to 125psi, optional interior lights, Lookbox for physical inspection, and vapor-free sampling.
- Collection Header Above-ground substitute for underground sulfur storage pits, designed to house multiple SulTraps to form a single process system; can be combined with microbubble diffusers for liquid sulfur degassing, with options including 100% jacketing, bolt-on heating panels, or patented reflective insulation heating.
- Multi-Point SO2 Injection Patented process for producing sulfur dioxide externally and injecting it into a thermal reactor, reaction vessel, or H2S location to significantly increase capacity of Claus and tail gas units while eliminating the need for additional thermal reactors, waste heat boilers, and traditional re-heaters; includes the No-monia process for sour water stripper gas.
- Pressure Surge Relief Device (PSRD) Patent-pending large-volume relief system that does not rely on springs, fully steam-jacketed, with a removable internal shaft for inspection, nitrogen/instrument air pad, and a unique self-resealing capability applicable across many industries.
- Sul-Tower Patent-pending design combining a sulfur dioxide production tower with a standard Claus unit catalytic bed into a single vessel, decreasing plot space and overall cost while producing pure SO2 for injection into Claus units for capacity increase; calculated efficiency approximately 95% or higher.
- Sul-Clean Two-stage sulfur clean-up tower that removes or converts hydrogen sulfide compounds in sulfur produced by Claus recovery units, using a distribution system that increases bubble count and surface area, with a first stage for primary H2S/H2Sx removal and a second polishing section with fresh air contact.
- Consulting Services Engineering, design, and analysis consulting for all Sulfur Recovery Unit (SRU) equipment, drawing on over 100 years of collective experience in the sulfur recovery industry.
- Inspection/Troubleshooting Services On-site system analysis and recommendations for existing sulfur plants to identify issues and optimize performance.
- Start-Up Training Services Equipment start-up and maintenance training provided to customers for their sulfur recovery systems.

Sulfur Operations Support competitors and assessment
Company assessmentEmerging players
- Koch Modular Process Systems: Specialty process equipment vendor serving sulfur and chemical processing customers — comparable niche supplier whose modular equipment competes in adjacent process unit applications.
- Topsoe: Licensor of sulfur recovery catalysts and processes for Claus and tail gas units — comparable as a technology provider whose reference designs can either include or displace SOS's mechanical innovations.
- Shell CANSOLV: Licensed tail gas treating technology for SO2 removal from Claus offgas — comparable because it addresses the same SRU emission control workflow that SOS's Sul-Clean and Sul-Tower target.
Broad incumbents
- Worley Limited: Global EPC contractor that designs sulfur recovery units and tail gas treatment systems for refineries and gas plants — directly comparable as a full-scope provider that competes with SOS at the project specification level.
- Technip Energies: Major EPC and process technology licensor for refineries, gas processing, and sulfur recovery — comparable because it sells integrated SRU designs in which SOS's components must be specified.
- Wood Group (formerly Amec Foster Wheeler): EPC contractor with deep sulfur recovery and tail gas treating heritage — comparable incumbent that designs and procures SRU equipment for global oil & gas clients.
- Black & Veatch: Engineering firm that delivers sulfur recovery, tail gas, and gas processing projects — comparable broad EPC that competes for the same refinery and gas plant specification opportunities.
- Jacobs Solutions: Global EPC and consulting firm with significant sulfur recovery and refining process capabilities — comparable incumbent that can bundle competing equipment into SRU designs.
- Linde Engineering: Engineering arm of Linde that licenses gas processing and sulfur recovery technologies — comparable process licensor whose designs influence whether SOS components get specified.
Direct peers
- Merichem Company: Specialty provider of sulfur and mercaptan removal technologies for refineries and gas plants — directly comparable niche player competing in the same sulfur processing value chain as SOS.
