IntelliRed™ remote gas detection system

ExxonMobil Research Qatar (EMRQ) and Providence Photonics co-developed the IntelliRed™ dual imager remote gas detection system, which provides a highly sensitive and accurate early warning of hydrocarbon leaks. The system is designed to improve process safety and environmental performance at oil refineries, chemical plants, liquefied natural gas (LNG) facilities and other gas processing facilities and can be used world-wide.

The dual imager IntelliRed™ system employs two infrared cameras with a common optical path. One imager operates at a wavelength slightly offset from the other, allowing one imager to detect both hydrocarbon and background signatures, while the second imager only detects the background signature. Image subtraction techniques eliminate background interference, which increases hydrocarbon plume detection accuracy, simplifies the autonomous computer vision algorithm and improves continuous scanning of a given landscape for aerial surveillance applications.

Scientists at EMRQ and Providence Photonics developed the system over a four-year period, culminating in field tests of the system at production facilities in Qatar and the United States. In 2015, ExxonMobil awarded Providence Photonics a global commercial license for the system.
