Lexington Group International

What Lexington Group International does

Lexington Group International, Inc. (LGI) is a privately held Texas-based engineering, procurement, and construction management (EPCM) firm founded in 1971. It operates two divisions — an engineering headquarters in Dallas and a construction management office in The Woodlands — and serves enterprise customers across petroleum refining, natural gas processing, petrochemicals, specialty chemicals, and semiconductor manufacturing. LGI delivers full-scope services from feasibility studies, front-end engineering design (FEED), and detail design through procurement, fabrication oversight, construction management, operator training, and startup/commissioning, with additional compliance offerings in PHA/PHM, OSHA, and environmental permitting.

The company builds its offering around proprietary process technologies including HighSulf acid gas enrichment, HighSulf Plus tail gas treating, custom acid gas burner designs, specialty chemical process skids, and the Equilibrium Composition Evaporator (ECE) for semiconductor CVD applications. Manufacturing is performed through a core partnership with Consolidated Fabricators, Inc., which fabricates LGI-engineered pressure vessels (ASME Section VIII Div. 1), process piping (ASME B31.3), OSHA-compliant platforms and guards, and specialized equipment under LGI's proprietary designs. LGI employs an in-house staff of professional engineers, project managers, cost estimators, and procurement specialists, and supports both GOST/GOST-K specifications for CIS-region clients and standard U.S. codes domestically.

LGI generates revenue through project-based professional services contracts (engineering, procurement, construction management) bundled with custom equipment fabrication, supplemented by post-startup operations consulting, training, and troubleshooting. Pricing is not publicly disclosed and varies by project scope and complexity. Customers — Holly Frontier, Texas Instruments, Navajo Refining, Nostrum Oil & Gas, REC Silicon, Oxy USA, Kerr McGee, Flint Hills Resources, Huntsman Chemical, ST Microelectronics, CONOCO, FMC, Shell Venezuela, and Petrofac — are sourced primarily through direct enterprise relationships and industry reputation rather than marketing-led demand generation.

Broad incumbents

• Bechtel Corporation: Largest privately held EPC firm globally with major downstream and energy practices — competes for large-scale refining and gas processing awards but operates at a fundamentally different scale than LGI.
• Worley Limited: Global energy, chemicals, and resources EPCM and consulting firm; overlaps directly with LGI's refining, gas processing, and petrochemical project work and operates in the same CIS/Asia geographies.
• Petrofac Limited: Global EPCM and operations services provider focused on upstream, midstream, and refining; shares LGI's CIS and Middle East project exposure but at materially larger scale and broader scope.
• Wood Group (Wood plc): Engineering and consulting firm with deep downstream and chemicals practices; comparable to LGI in service mix but global in scale and broader in client base.
• Technip Energies: Energy-focused EPCM and technology provider with strong LNG, refining, and petrochemical capabilities — competes for the same midstream gas and refining process unit awards as LGI.
• Burns & McDonnell: US-headquartered EPCM firm serving oil & gas, refining, petrochemical, and power; overlaps with LGI on refinery and midstream gas projects but with broader sector coverage and larger bench.
• Fluor Corporation: One of the largest global EPCM firms with significant downstream/petrochemical and gas processing practices — competes for the same refining and gas treatment work as LGI but with vastly greater bench capacity.

Direct peers

• GTC Technology US: Specialty process technology licensor and engineering firm serving refining, petrochemical, and gas processing — directly comparable to LGI's proprietary acid gas / sulfur recovery and process skid offerings.
• Audubon Engineering Companies: Mid-sized EPCM and field services firm focused on oil & gas, refining, petrochemical, and pipeline projects across the US Gulf Coast — closely comparable to LGI in scale, service mix, and customer profile.

Others

• Honeywell UOP: Process technology licensor for refining, petrochemical, and gas processing — comparable to LGI's proprietary process technology offerings (HighSulf, ECE) but operating primarily as a licensor rather than EPCM provider.
