The calibration/verification system and method for gas imaging infrared cameras standardizes the procedures to objectively and consistently check performance of gas imaging infrared cameras. This system includes a background board maintaining a uniform temperature, a target cell filled with a target compound and disposed in front of the background board, a reference cell filled with a reference compound and disposed in front of the background board, and an analyzer coupled to the camera that captures images of the gas cell and the reference cell. The analyzer compares the intensity difference and the temperature difference of rays passing through the target cell and reference cell to a reference relationship data of a quality control chart to determine whether the camera is in a working condition. The method is further extended to provide a quantitative measurement of a hydrocarbon plume from a gas imaging infrared camera.

A new concept for monitoring flare combustion efficiency (CE) was presented in the American Fuel & Petrochemical Manufacturers 2012 Environmental Conference in Denver, CO. A discussion covers this new concept, along with its theoretical basis and feasibility. The CE could be monitored in real-time through a multi-spectral IR imager that was capable of measuring IR radiance intensity. An experiment was conducted to prove the concept in real time. The CE determined by this method correlated well with the true CE measured by extracted samples analyzed by conventional approaches. With a further refined calibration approach, more accurate CE measurement is expected. This new technology can determine CE at a pixel level, each pixel representing a portion of the flare flame in the field of view. In addition, the technology will provide temperature mapping of the flare flame, which is also related to the performance of the flare. This is an abstract of a paper presented at the Environmental Conference 2013 (New Orleans, LA 10/21-22/2013). Source
