Flare Gas Monitoring
Analytical Solutions for Flare Gas Monitoring
Flare Gas Monitoring & Real-Time Flare Gas Analysis for EPA Compliance
FOR YOUR FLARE GAS COMPLIANCE
Process Insights provides complete flare gas monitoring systems for refineries, petrochemical plants, chemical manufacturing, LNG facilities, and oil & gas operations. Our real-time analytical solutions continuously measure Net Heating Value (NHV), BTU, Wobbe Index, Combustion Air Requirement Index (CARI), Total Sulfur, H₂S, and complete flare gas composition to help facilities optimize flare performance, improve combustion efficiency, reduce emissions, and comply with evolving environmental regulations.
Why Flare Gas Monitoring Matters
Industrial flares protect facilities by safely burning excess hydrocarbons during normal operation, process upsets, and emergency pressure relief.
However, changing gas composition directly affects:
- Combustion efficiency
- Destruction efficiency (DRE)
- Flare stability
- Methane emissions
- Steam consumption
- Supplemental fuel usage
- Environmental compliance
- Operating costs
Continuous flare gas analysis enables operators to make immediate process adjustments that improve flare performance while reducing emissions.
Meet EPA & Global Environmental Regulations
Process Insights solutions help facilities comply with current and evolving regulations, including:
- EPA Refinery Sector Rule (RSR)
- Quad O / OOOO
- Quad Ob
- Quad Oc
- MON
- HON
- EMACT
- Subpart Ja
- HRVOC
- Local refinery and petrochemical emission regulations
Real-time analytical data supports documentation, reporting, and process optimization while helping facilities achieve required destruction efficiencies.
What is Quad O?
We specialize in midstream applications and customize flare gas monitoring solutions to match your operational needs and budget. Whether you need compliance support or process optimization, we’re ready to help.

WHY YOU SHOULD USE OUR GAS ANALYSIS SOLUTIONS

Accurate measurement
Flare gas monitoring requires accurate measurement of the flow rate and composition of the gas being flared. However, the high temperature and pressure of the gas can make accurate measurement challenging, as can the variability in the gas flow and composition.

Reliable Operation You Can Trust
Flare gas monitoring equipment must be able to operate in a range of environmental conditions, including extreme temperatures, high winds, and heavy rain. This can be challenging, especially in remote locations where access to power and other infrastructure may be limited.

Meet Regulatory compliance
Flare gas monitoring is subject to regulatory requirements in many jurisdictions, and companies must be able to demonstrate compliance with these requirements through regular monitoring and reporting. This can be challenging due to the complexity of the regulations and the need for accurate data and reporting systems.

Avoid Fines
Non-compliant companies may face fines or penalties that can be significant, especially for repeated or willful violations of regulations.

reduce Shutdowns
Regulators may require a company to shut down operations if they are found to be in violation of flare gas regulations. This can result in significant financial losses and reputational damage.

Avoid Reputational damage
Companies that are found to be non-compliant with flare gas regulations may face negative publicity and reputational damage, which can have long-term impacts on their business.
