Fixed Forward Looking Infrared Camera (FLIR)
The Fixed Forward Looking Infrared (FLIR) camera is an optical gas imaging (OGI) instrument that visualizes and pinpoints gas or vapor emissions from a distance. The system detects infrared energy (heat) and converts it into an electronic signal which is then processed to produce a thermal image on the unit’s onboard video monitor. The OGI camera provides remote indication that chemical gases/vapors (visible or invisible) are present based on the difference in temperature of the gas from the background temperature. The technical details for the FLIR camera can be found here.
In the pilot-scale demonstration, the units will be used to detect emissions from primary sources (Exhausters and Passive Breather Filters) and fugitive sources if present. If the Fixed FLIR indicates vapors are present, other vapor monitors with the capability to detect speciation and concentrations will be used to confirm the FLIR results. The fixed FLIR camera will be co-located with a OP-FTIR unit in a tower which will allow unobstructed scanning of the AP tank farm.
