Environmental Compliance

Permanently installed analyzers that sample stack or flue gas to measure pollutant concentrations and flow on a continuous basis for regulatory reporting. Typical configurations track NOx, SO2, CO, CO2, O2, and volumetric flow against permit limits.

Instruments and survey services that locate and quantify methane and volatile hydrocarbon leaks from wellpads, compressors, tanks, and pipelines. Technologies include optical gas imaging cameras, laser and tunable diode spectrometers, and fixed sensor networks used for LDAR programs.

Selective catalytic reduction catalysts that convert nitrogen oxides to nitrogen and water using ammonia or urea reagent on engines, turbines, and fired heaters. Supplied as honeycomb, plate, or corrugated catalyst blocks sized to the exhaust duty.

Vanadium-based catalysts that oxidize SO2 to SO3 in sulfuric acid plants and sulfur recovery units, and related sulfur abatement media. Used to control SO2 emissions and recover sulfur from sour gas processing.

Analyzers and control devices that measure and reduce particulate matter in stack gas and ambient air. Includes opacity monitors, dust analyzers, and the instrumentation feeding baghouse and electrostatic precipitator performance reporting.

Consulting services that prepare air, water, and waste permit applications and conduct environmental impact studies. Covers NEPA assessments, state-level reviews, and regulatory submittals required before construction and operation.

Field services that remediate, restore, and re-vegetate disturbed sites at end of life and divert waste streams from landfill. Includes well pad reclamation, soil remediation, and waste characterization and recycling.

Services addressing greenhouse gas accounting, carbon offsets, and geologic CO2 storage. Covers emissions inventories, carbon intensity reduction programs, offset procurement, and carbon capture and sequestration project support.
