Gas Detection and Identification


With the Telops Hyper-Cam Methane, scientists are able to detect and identify methane present in a scene, and to locate it precisely in an image or video, pixel by pixel. Recently, scientists from Linköping University, in Sweden, were thus able to « film » methane emissions in real time – a breakthrough that could play a significant role in the fight against climate change. Their results were published in the prestigious journal Nature Climate Change.
methane detection 3d reconstruction
The Telops Hyper-Cam has been successfully used by Total E&P under an R&D project to demonstrate the real-time 3D reconstruction of methane gas clouds. During the experiment, three Hyper-Cams were installed around the area being observed and networked to a central computer. Each Hyper-Cam produced in real-time a radiometrically calibrated hyperspectral image. The computer merged the hyperspectral data from the imagers to compute and display the 3D cloud as well as to estimate the leak rate. Total's work has been presented at the SPE/ATCE Conference in Dubai, UAE, on September 28th, 2016.

Infrared imaging can help visualize fugitive emissions and small gas leaks under various environmental conditions and industrial contexts. As many gases are toxic and/or flammable, like natural gas (CH4), efficient gas detection from a remote location is advantageous for safety purposes. The selectivity brought by high-resolution infrared hyperspectral imaging allows to identify the chemical nature of the gases, reducing at the same time the frequency of false alarms.

Characterization of mechanical properties such as Young’s modulus, shear strain, viscosity and fracture toughness is very important in the development process of new alloys and composite materials. Researchers typically carry out many different measurements like tensile displacement tests, compression tests and fatigue tests using extensometer and split-Hopkinson bars setups. Infrared imaging allows to characterize the energy released by the investigated material as it undergoes elastic and plastic deformation up to the fracture point.

Infrared imaging of jets provide a new and simpler method to measure vapor-fuel penetration, which is critical for designing high-efficiency engines.

Most combustion reactions generate infrared-active gases such as carbon dioxides (CO2) and water vapor as well as known pollutants like carbon monoxide (CO) and nitrogen oxides (NOx). On this regard, infrared imaging represents an interesting diagnostic tool as it allows chemical imaging and temperature measurement at the same time. High-speed infrared imaging is useful for characterizing fuel injection, ignition and combustion in internal combustion engines (ICE), gas turbines or jet engines, regarding which lowering fuel consumption and soot generation represents an important research aspect.
