Refinery Gas Analysis and Process Monitoring

When Your Refinery Depends on Reliable Gas Measurements

Accurate gas analysis helps you control critical processes, reduce emissions, and maintain safe and stable refinery operations.

Understanding Your Refinery Environment

Refinery processes run continuously and under demanding conditions. Even small variations in gas composition can affect efficiency, safety, and compliance.

Across units such as heaters, furnaces, sulfur recovery units, and gas processing systems, you rely on accurate and continuous measurements to maintain control.

At the same time, increasing environmental requirements and operational demands make it necessary to work with data you can trust – in real time.

For Refinery these are some of the parametres we can help you measure, monitor and analyse:

  • O₂ (oxygen)
  • H₂S (hydrogen sulfide)
  • SO₂ (sulfur dioxide)
  • Total sulfur compounds
  • CO (carbon monoxide)
  • CO₂ (carbon dioxide)
  • NOx (nitrogen oxides)
  • CH₄ (methane)
  • Hydrocarbon dew point
  • Trace components in complex gas mixtures

Your Challenges in Refinery Operations

Keeping Processes Stable Under Changing Conditions

Gas composition and process conditions rarely remain constant. Variations can impact combustion efficiency, sulfur recovery, and overall plant performance.

To maintain control, you need reliable measurements that reflect what is actually happening in your process – not delayed or inferred data.

Documenting Emissions and Staying Compliant

Regulatory requirements require continuous monitoring of key components such as sulfur compounds and combustion gases.

In practice, this means your measurements must be stable, traceable, and available at all times.

Operating in Hazardous and Demanding Environments

Refinery installations often involve high temperatures, pressure variations, and explosive atmospheres.

Your measurement systems must operate reliably under these conditions while meeting ATEX and functional safety requirements.

Maintaining Uptime and Reducing Maintenance

Unplanned downtime affects both production and safety.

You need solutions designed for continuous operation, with predictable maintenance and stable performance over time.

Understanding Complex Gas Compositions

Refinery gas streams can contain multiple components across wide concentration ranges.

This requires flexible measurement technologies that provide both detailed insight and consistent accuracy.


How Gas Analysis Supports Your Refinery

Sulfur Recovery and Tail Gas Monitoring

In sulfur recovery units, maintaining the correct H₂S/SO₂ ratio is essential for efficient operation.

Continuous measurement allows you to control the Claus process more precisely, improving recovery efficiency and reducing emissions.

Combustion Control in Heaters and Furnaces

Accurate oxygen measurement enables you to control the air-to-fuel ratio in real time.

This allows you to improve combustion efficiency, reduce fuel consumption, and limit emissions – while maintaining stable operation.

Multi-Component Gas Analysis for Process Insight

When you need to understand your gas composition in detail, single-parameter measurements are not enough.

Gas chromatographs provide a complete picture of your gas stream, helping you detect deviations early and improve process control.

In-Situ Monitoring in Hazardous Areas

In-situ measurement technologies provide immediate data directly from the process.

This reduces the need for complex sampling systems and gives you faster response times in safety-critical applications.

Gas Quality and Dew Point Control

Hydrocarbon dew point plays a key role in preventing condensation and protecting your infrastructure.

With continuous measurement, you can ensure gas quality and avoid operational issues related to condensation.

Integrated Control and System Solutions

When your measurement systems are integrated into your control environment, you gain better visibility and faster decision-making.

This makes it easier to manage your process and maintain stable operation across the refinery.


What This Means for Your Operation

  • More stable and efficient process performance
  • Better control of emissions and regulatory compliance
  • Increased safety in hazardous environments
  • Reliable, real-time data for operational decisions
  • Reduced downtime and more predictable maintenance
  • Improved product quality and process consistency
