Flare Radiation and Dispersion Study

What is a Flare Radiation and Dispersion Study?

A Flare Radiation and Dispersion Study analyzes the impact of flare stacks used in industries to burn off combustible gases. It evaluates the thermal radiation and dispersion of gases to ensure safe and environmentally compliant operations.

Overview

Flare stacks are critical components in industrial processes, intended to safely burn off gases and prevent potential environmental hazards. Proper combustion is crucial to meet strict regulatory standards and minimize environmental impact. Our Flare Radiation and Dispersion Study evaluates and reduces the release of toxic gases, ensuring compliance with international environmental regulations.

Why is a Flare Radiation and Dispersion Study Essential?

  • Regulatory Compliance: Ensuring adherence to stringent environmental regulations, including standards set by the EPA and OISD.
  • Safety Assurance: Protecting the environment and public health by minimizing the hazardous effects of flare emissions.
  • System Optimization: Enhancing the efficiency, safety, and reliability of flare systems.

Our Methodology

Our experts perform the study in accordance with the applicable international standards such as EPA, OISD etc. and suggest the necessary changes for improvement in the flare system. Working in close coordination with client, we collect the data related to flare stack and execute the study considering the worst-case scenario of flaring.

The data required from the client

  • Height of the flare tip from the ground level.
  • Diameter of the flare tip
  • Flow rate of the flared gas
  • Composition of the flared gas
  • Operating temperature of the flare
  • Operating pressure of the flare
  • Concentration of interest
  • Wind speed and direction

Case Studies

Using the collected data, we conduct various case studies by altering the flow rate, gas composition, and environmental conditions. This helps us identify potential hazardous situations and recommend improvements.

Advanced Software Tools

We utilize industry-leading software such as:

  • PHAST
  • FlareSim
  • AERMOD

These tools allow us to simulate and analyze flare radiation and dispersion under different scenarios. The results are thoroughly documented and reported to our clients.

Deliverables

Depending on the project scope, we offer a comprehensive range of deliverables, including:

  • Basic Engineering Design Support
  • Technical Assistance
  • Graphs and Contours for:
    • Lower Flammability Limit (LFL) Cloud
    • Thermal Radiation Levels
    • Toxic Substance Dispersion

Model Outputs

Based on chosen exposure limits like STEL, IDLH, and ERPG, our models provide:

Heat Radiation Contours: Detailed graphs showing radiation levels versus downwind distance under various wind conditions.

Graph showing radiation versus distance for a jet fire flare tip, with different categories of fire intensity (1/F, 2/F, 3/F, 5/F) represented by distinct lines. The x-axis represents the downwind distance (m) while the y-axis indicates radiation levels (kW/m²). The graph illustrates how radiation decreases as the distance increases.

Toxic Release Contours: Graphs illustrating cloud height versus distance downwind, helping validate the flare's location and height.

Side view graph showing flare tip behavior with four categories (1/F, 2/F, 3/F, 5/F) and corresponding flare emissions at different flow rates (31 ppm, 81 ppm). The x-axis represents the downwind distance (m) while the y-axis shows the cloud height (m), illustrating variations in flare height and dispersion over distance

Conclusion

Our Flare Radiation and Dispersion Study not only validates the existing flare system but also ensures its compliance with environmental regulations. By optimizing the flare system's p erformance, we help safeguard the environment and public health.
