Flare Stack Monitoring

Thermal imaging cameras can be used to identify correct pilot ignition, proper burning profiles and basic flare conditions

PRINTABLE PDF

Many industries use flare stacks to burn off unwanted waste gas byproducts or flammable gasses released by pressure relief valves during unplanned over-pressuring of plant equipment. Applications include oil and gas drilling operations, oil refineries, chemical process plants, gas distribution infrastructure, and landfills. In many cases, regulations require monitoring of a stack’s flame, or the pilot flame that ignites the gasses, to avoid having unburned hydrocarbons enter the atmosphere.

Viper can help you meet the HSE needs of the industry.

Viper's System Solution

Thermal Imaging cameras distinguish between the heat signature of the flare stack and the surrounding environment (typically, the sky or clouds). The cameras can be positioned to monitor not only the stack flame but also the igniter flame. Cameras are mounted on a structure in weather-resistant housing. Calibration and spectral response allows them to obtain a clear image and measure temperature of the flare stack or pilot flame. Even flares invisible to the naked eye are clearly evident on a thermal image.

Specific capabilities:

  • Gas Detection: highly sensitive detectors with low false alarm rates
  • Gas Quantification & Concentration: determines mass flow rate and ppm-m of gas
  • Flare Monitoring: real-time performance monitoring with early detection of liquid carryover
  • Flame Detection: reliable tool for clear image and temperature measurement
  • Through-Flame Thermography: accurate temperature measurement through fire
  • Flare Efficiency: smoke index warning, destruction and removal efficiency indicator

System Solution Components

Optical Gas Imaging cameras are integrated with ViperOptic software which directly communicates with most industrial platform controllers. The software will analyze and compare the data against predefined parameters and will trigger an alarm if warranted. These parameters can be adjusted based on the specific application needs.

Every thermal imaging camera is mounted in an industrial camera enclosure that uses the appropriate purge and pressurization to protect the camera equipment. Viper Imaging provides solutions for Class I and Class II environments that are Division I or II.
