Gas leaks are of concern to petroleum refiners and industry. They need to inspect facilities regularly to check for leakage. Currently used handheld sensors, called "sniffers," draw air into a flame ionization detector but need proximity to a leak source to work, meaning that they can only detect leaks on a point basis. However, the Remote Sensing Group has developed optical imaging techniques that can locate and detect gas leaks by visually surveying a complete area. Optical imaging uses infrared wavelengths to view a scene. Any leaking plumes of gas show up as opaque on the video screen. This method is a more effective, less costly and labor intensive way to detect leaks.
