Optimized Gas Treating

What Optimized Gas Treating does

Optimized Gas Treating, Inc. (OGT) is a privately held Texas corporation founded in 1992 that develops specialized chemical process simulation software for gas treating and sulphur recovery operations. The company's core products include ProTreat, the world's first mass and heat transfer rate-based absorber simulator for amine systems and related acid gas removal operations; SulphurPro, a kinetics-based simulator for sulphur recovery units using fundamental reaction mechanisms rather than curve-fit approaches; and ProBot, a Microsoft Excel-based application that connects to data historians or DCS systems to provide automated performance monitoring and advisory diagnostics. The integrated OGT|Suite platform combines these products with full CAPE-OPEN compliance, enabling interoperability with other engineering software such as HTRI's Xchanger Suite. OGT's unique corrosion prediction model for amine systems, sour water systems, and waste heat boilers is described as not available in other simulators.

OGT monetizes through three primary revenue streams: subscription-based software licensing for ProTreat, SulphurPro, and OGT|Suite (modular, customizable to customer needs, billed annually); professional engineering consulting services including unit reviews, troubleshooting, optimization, corrosion analysis, and custom simulation development; and training and workshops delivered via WebEx/Teams/Zoom or face-to-face at customer facilities and in Houston, TX. The company sells primarily through direct enterprise field sales with dedicated sales engineers, supplemented by an international channel partner network covering the Middle East, India, Western Pacific, China, South Korea, Europe, and Africa.

The customer base spans engineering and consulting firms (EPCs and independent consultants), oil and gas E&P companies, refineries with acid gas removal and sulphur recovery units, LNG and fertilizer plants requiring deep CO2 removal, and academic institutions. Named end users include a European EPC company, a Kazakhstan-based E&P company, Canadian and Dutch consulting firms, a Houston-based process equipment supplier, and the Technical University of Munich. The company is founder-led, with Ralph H. Weiland (CEO, Ph.D., active in gas treating since 1965) and G. Simon A. Weiland (COO) anchoring leadership, and is supported by approximately 15 employees including Ph.D.-level chemical engineers. No external funding, acquisitions, or institutional investment has been disclosed; OGT operates as a bootstrapped, owner-operated niche software business.

Core offering

Optimized Gas Treating (OGT) develops and licenses specialized rate-based and kinetics-based process simulation software for gas treating (acid gas removal, dehydration, sour water stripping, LNG, ammonia syngas) and sulfur recovery units. Its product lineup centers on the OGT|Suite platform incorporating ProTreat and SulphurPro, with the ProBot add-on enabling automated unit monitoring. The company complements its software with engineering consulting, training, and workshops.

Product overview

Optimized Gas Treating provides a suite of specialized process simulation software products centered around OGT|Suite, which integrates ProTreat for acid gas removal simulation and SulphurPro for sulfur recovery unit simulation. ProBot adds automated unit monitoring capabilities. All products use mass and heat transfer rate-based modeling rather than traditional equilibrium-based approaches. OGT|Suite is fully compliant with CAPE-OPEN standards for integration with other engineering tools.

Scale indicators2 records

Recent moves5 records

Expansion highlights5 records

Direct peers

• Bryan Research & Engineering: Bryan Research & Engineering (BR&E) develops ProMax, a process simulator that directly competes with ProTreat for amine treating, gas processing, and sulphur recovery modeling. It is the closest head-to-head competitor in OGT's specific niche.

Broad incumbents

• Aspen Technology: AspenTech's HYSYS and Aspen Plus are general-purpose process simulation suites widely deployed in oil & gas, refining, and chemicals engineering. While broader in scope, they include gas-treating and sulphur recovery modules that overlap with OGT's specialized products.
• Honeywell (UniSim): Honeywell's UniSim Design Suite competes in process simulation for upstream, gas processing, and refining applications. As part of a much broader industrial software portfolio, it overlaps with OGT's gas-treating and sulphur recovery use cases but does not specialize in them.
• AVEVA: AVEVA acquired process simulation assets (PRO/II and related technologies) and offers them within its broader industrial software portfolio. AVEVA competes with OGT for engineering simulation decisions in EPC and operator organizations.
• Chemstations: Chemstations' CHEMCAD is a general-purpose process simulation suite used across chemical, oil & gas, and engineering services. It overlaps with OGT's simulation category but is broader and less specialized in amine treating and sulphur recovery.
• Process Systems Enterprise (Siemens PSE / gPROMS): PSE's gPROMS platform is a high-fidelity process modeling environment serving chemicals, energy, and pharmaceuticals. It competes with OGT for advanced simulation work where first-principles rigor matters, including gas processing and petrochemicals.
• KBC (Yokogawa): KBC, now part of Yokogawa, provides process simulation, consulting, and digital solutions for refining and petrochemicals. Its consulting-plus-software model overlaps with OGT's mix of simulation licensing and engineering consulting services.

Emerging players

• ProSim: ProSim (France) offers steady-state and dynamic process simulation software used in specialty chemicals, pharma, and some oil & gas applications. It is smaller in scope than AspenTech/Honeywell but overlaps with OGT in steady-state process modeling for niche applications.
• Sulfur Recovery Engineering: Sulfur Recovery Engineering provides consulting and engineering services focused on Claus SRUs and tail gas treating. While not a software peer, it competes for the same sulphur recovery engineering dollars that SulphurPro addresses via simulation.

Others

• HTRI (Heat Transfer Research, Inc.): HTRI develops the Xchanger Suite for heat exchanger design and integrates with OGT|Suite via CAPE-OPEN. HTRI is a technology/integration partner rather than a competitor, but operates in adjacent process engineering software.
