Abstract:
Apparatus and methods for rapidly detecting, localizing, imaging, and quantifying leaks of natural gas and other hydrocarbon and greenhouse gases. Scanning sensors, scan patterns, and data processing algorithms enable monitoring a site to rapidly detect, localize, image, and quantify amounts and rates of hydrocarbon leaks. Multispectral short-wave infrared detectors sense non-thermal infrared radiation from natural solar or artificial illumination sources by differential absorption spectroscopy. A multispectral sensor is scanned to envelop an area of interest, detect the presence and location of a leak, and raster scan the area around the leak to create an image of the leak. The resulting absorption image related to differential spectral optical depth is color mapped to render the degree of gas absorption across the scene. Analysis of this optical depth image, with factors including known inline pressures and/or surface wind speed measurements, enable estimation of the leak rate, i.e., emission mass flux of gas.

Claim (Index 33):
An imaging device for detecting, localizing, and imaging emission of one or more hydrocarbon gases from within a site to be monitored, the imaging device comprising:\n a multispectral optical sensor aligned and operable to detect light traveling along a line-of-sight of the imaging device to the site, wherein the multispectral optical sensor is responsive to light having wavelengths within one or more spectral absorption bands of the one or more hydrocarbon gases; a scanning actuator operable to scan the line-of-sight of the imaging device; and one or more processors operable to:\n (a) control the scanning actuator to trace the line-of-sight of the imaging device around a boundary of the site; and \n (b) access data corresponding to light detected by the multispectral sensor as the line of sight of the imaging device is traced along the boundary of the site, and use the detected light to detect the emission of the one or more hydrocarbon gases from within the site.
