Air Emissions Control Engineering

Integrated Permitting and Project Execution

On generation and industrial projects, the air permit is often the critical path. We coordinate technical inputs, equipment guarantees, permit milestones, agency responses, long-lead procurement, site design, and construction sequencing with your environmental specialists and permitting partners. Keeping regulatory commitments tied to the facility design is what surfaces schedule risk early, while there is still room to move before notice to proceed, equipment release, construction, or startup.

Criteria-Pollutant Controls for Turbines and Natural Gas Generation

• Selective Catalytic Reduction Systems – NOx control for mobile turbine packages, temporary or leased generation, peaking facilities, and permanent stationary sources.
• Reagent and Catalyst Systems – Ammonia or urea storage, forwarding, injection grids, mixers, catalyst reactors, controls, and ammonia-slip management.
• Oxidation Catalyst Systems – Control of carbon monoxide and volatile organic compounds from natural gas engines and turbines.
• Exhaust and Stack Integration – Ducting, silencers, dampers, bypasses, expansion joints, stacks, foundations, and structural supports.
• Monitoring and Verification – Instrumentation, continuous or parametric monitoring, alarms, interlocks, commissioning, tuning, and performance testing.
• Thermal Oxidizers – Waste-gas handling, burners, combustion air, fuel gas, heat recovery, burner-management systems, controls, and brownfield tie-ins.

Oil and Gas Flare and Combustor Systems

• Elevated and enclosed flare systems
• Enclosed combustors and vapor-combustion units
• Acid-gas and waste-gas thermal oxidizers
• Flare headers, knockout drums, liquid seals, pilots, ignition, purge gas, and flame detection
• Vapor-recovery and flare-gas-recovery interfaces
• Fuel gas, instrument air, electrical, controls, SCADA, and utility integration
• Brownfield tie-ins, piping, foundations, structural supports, equipment layouts, and constructability planning
• Procurement, construction management, commissioning, startup, and performance verification

Air Emissions FEED, Engineering and EPC Delivery

We support air emissions projects from feasibility and permit-basis development through FEED, detailed engineering, procurement, construction management, commissioning, and startup. Fewer contractors across that scope means fewer gaps between packages, and our process, mechanical, piping, civil, structural, electrical, instrumentation, and controls groups build a facility that can be operated the way it was permitted.
