Sherlock is a small hand held; battery operated imaging spectrometer that has been designed for gas leak imaging, quantification and analysis. Sherlock has been field tested at numerous petrochemical, refining and processing plants where it has demonstrated that it has the sensitivity to see gas leaking at flow rates as low as 1 gram per hour. Applications for the Sherlock range from environmental monitoring, safety and risk mitigation to process control for all types of industries; oil, gas, chemical, power generation, mining, pulp & paper, just to name a few. Sherlock is based on patented IMSS spectral imaging1 technology that has been proven for several Department of Defense related applications. Now this technology is available to the commercial market and has been developed for several applications related to gas imaging, analysis and quantification.

Sherlock comes in various models with different infrared spectral sensitivity depending on the application.

Sherlock VOC is a fugitive gas imaging and quantification camera that can be used for LDAR as an alternate to Method 21 soon to be mandated by law. The Sherlock VOC enables the user to see an invisible gas leak and determine the mass of its emission over time (that is, it quantifies the amount of the leak). Sherlock VOC can log data, and video records the leaking gas and components that need repair under the LDAR program LDAR. Moreover, the video clips of leaks can be stored for verification and auditing purposes.

Sherlock FE is a remote imaging system that is used to determine the efficiency of flares as well as continuous emission monitoring of the greenhouse gas CO ­ 2 from stacks for cap and trade applications such as the Kyoto Treaty, the Gas Star Program and the Regional Greenhouse Gas Initiative (RGGI).

Sherlock VOC

Designed specifically for fugitive gas leak imaging of hydrocarbon species The Sherlock sees the invisible. The battery operated Sherlock can easily be carried by a technician around a plant facility looking for leaking gas. Sherlock can be used for leak detection and repair activities as well as risk mitigation and safety. Using Sherlock to locate large leaks before a source can ignite the volatile gas causing a catastrophe with potential injury or even fatality and. undue damage to facilities, and equipment.

To human eye gas is invisible	With Sherlock gas is made visible

Sherlock FE

Infrared imaging spectrometer designed for monitoring the efficiency of flares, stack emissions and the greenhouse gas CO2 emission from vent and smoke stacks. Sherlock’s ability to image and monitor emission from stacks is demonstrated the images below taken remotely of a stacks on the right and a flare on the left which are examples of a typical Sherlock Image and the resultant spectra. The enclosed flare as imaged on the left has a large CO2 emission as indicted by the broad spike in the red spectra. The stack as imaged on the right is releasing what appears to be H2S (a deadly gas) into the atmosphere as indicated by the blue spectra. Sherlock can be used to monitor numerous stacks in a plant form a single remote location and thus save considerable cost in stack emission monitoring as well as flare analysis.

Sherlock can also be used for flare and stack efficiency analysis. In this manner it can be used for process control by feeding back the efficiency measurement from a remote location via Ethernet to the control room, where the process can be adjusted for maximum efficiency which can save added cost in the use of unnecessary fuel oil. In this manner it can be used for continuous emissions and efficiency analysis.
