Introduction to Optical Gas Imaging (OGI) Technology


  • OGI Technology helps to find gas vapor leaks quickly, saving time and money.
  • OGI displays invisible gases as clouds of smoke in the video data.
  • OGI Operators can scan broad sections of survey areas and equipment rapidly.
  • OGI helps to detect methane, sulfur hexafluoride, and hundreds of other industrial gases.
  • OGI Program is great investment with significantly high RoI.

Who should use OGI?


  • Maintenance Team to identify leaking components, prioritize repairs and check repair effectiveness.
  • Environmental Team to inspect and monitor leaking components for fugitive emissions and leaks analysis.
  • Safety Team to inspect and monitor job site for any possible invisible leaks leading to hazards and risks.
  • Pipeline Patrol Team to detect and identify random emission leaks points.
  • Liquid Fuel Storage Tank Operations Team to detect, identify and monitor emission leaks.
  • Fuel Logistics Team to identify Transportation wastage emission leaks.
  • Solid Fuel Storage and Handling Teams to identify hotspots for timely preventive action.

Why use OGI Technology?


  • Visual Evidence based emission leak identification, tracking and reporting.
  • Qualitative and Quantitative Analysis for prioritizing component emission leak repairs.
  • Cost-effective Gas / Vapor Leak Detection.
  • Can Operate to Detect Emission Leak from Safe distance.
  • Easy collaborate and share Component Emission Leak Video Data across teams.
  • Identify Emission Leaks when they are small and starting.
  • Highly accurate Emission Leak pin point location identification.
  • Can detect emission leak of inaccessible components.
  • Consistent and Reliable results.

How OGI Technology works?


  • Optical Gas imaging is a highly specialized infrared camera.
  • It uses quantum detectors which are cooled to cryogenic temperatures around -200℃ by Stirling Cooler.
  • Optical Gas imaging uses spectral filter method to detect the gas compounds.
  • The gas compounds infrared absorption characteristics is wavelength dependent.
  • The mounted filter allows very specific radiation wavelengths to pass through to cooled quantum detector.
  • When gas cloud exists between the background object and camera, the gas absorbs radiation.
  • The amount of radiation passing through the cloud to the cooled quantum detector will be reduced.
  • This radiation contrast between gas and background is captured by detector and converted into visual data.
