The Sherlock® FE is being developed to monitor and quantify the emission of high temperature gases such as those emitted from stacks and flares. The Sherlock® FE has the potential to be used to quantify greenhouse gas emissions from flares and stacks for cap and trade applications. It can remotely monitor and generate a pixel-by-pixel quantitative analysis of flares and smokestacks emissions. In many circumstances this can be done from a remote location that can be miles from the source. Other applications include flare efficiency analysis, process control, regulatory monitoring of emission as well as greenhouse gases emission quantification.

Shown to the bottom right is an infrared imaged and spectral signature as measured by a Sherlock FE of a stack burning efficiently (red) and another burning inefficiently (blue). When a stack or flare is burning efficiently, the gases being burnt convert to CO2 so the infrared signature shows a spike at the wavelength of CO2 and no spikes at the signarue wavelength of the burning gases. This is demonstrated by the red line in the graph where efficency of the burn is very hight. Conversely, when the harmful gases are not being burnt efficiently, there is a smaller signature at the CO2 wavelength and a larger signature at the wavelengths of the gases that are not burning. The blue line in the spectra shows an inefficient burn which indicates that unintended pollutants are going into the atmosphere. Being able to monitor flare efficiency as well as identify and quantify the types of gasses being emitted into the atmosphere is extremely important for environmental monitoring and cap-and-trade programs. The ability of a third party to do the monitoring from great distances can help to keep industry honest.
