Optical Gas Imaging
Visualization of fugitive emissions
Page last modified
January 14 2025
Infrared cameras which enable the visualization of fugitive emissions from plant, pipework and machinery. Both hand held and fixed mount cameras are available which depending upon their specification can visualize either specific gases such as CO2 or a range such as hydrocarbons. The cameras can record an optical image of the item emitting the gas/vapour as well as the IR Video of the emission.
Pros & Limitations
1
Portable so can scan form any angle
1
Nearly 300 gases can be visualised with the hydrocarbon versions
1
Record both visual and IR image /and video of emission
1
Different lens options depending upon location to be viewed - lens available 6 degree 14.5 degree or 24 degree
1
Can be complimented by quantification capability, now integral with the new G series
1
Multi functional - dual use cameras, they can also be used for normal IR thermography
1
Very sensitive
0
Can’t detect if very high winds and very small leak
Specification
Specification Title | Specification Description |
---|---|
Areas of Application
|
The main application area for this technology is hydrocarbon processing and storage facilities both on and offshore.
|
ATEX certified
|
The Gx320 and GX620 are ATEX certified and ATEX housing can be provided for others.
|
Capabilities
|
The cameras enable operators to demonstrate that their processes and equipment are functioning correctly and if not highlight any areas of concern. They now form part of regular plant heath checks.
|
Compliance
|
Such technology is validated by Environmental Agencies for demonstrating Emissions limits and meeting the new EU methane reduction targets
|
Condition based maintenance
|
Many operators use this technology as part of their condition monitoring practices, verifying if leaks & seeps are changing.
|
In-service inspection possible
|
The cameras can only visualise emissions when plant is operating.
|
Inspection
|
As an inspection tool, the camera can not only visualize emissions but thermographers can also use it to check rotating machinery and electrical plant for hot spots.
|
Measurement
|
The G series cameras now integrate some of the quantification ability for measuring hydrocarbons and can be operated with the QL320 Quantification tablet to enable mare accurate quantification to be made of hydrocarbon emissions.
|
Monitoring
|
The cameras are widely used for monitoring process plant for deterioration with technicians doing weekly walk rounds.
|
Safety
|
Checking for un expected emissions forms part of good practice in any safety regime and being able to visualise leaks from a distance aids maintaing safe work environments.
