Multi-component gas analyzers help FAA monitor jet fuel

A multi-component gas analyzer from Rosemount Analytical is helping the Federal Aviation Administration (FAA) find safer jet fuel solutions.

Striving to reduce the possibility of in-flight fuel tank explosions, the FAA’s William J. Hughes Technical Center has been performing laboratory tests to seek ways to make jet fuel safer. Until recently, it has been unable to obtain real-time in-flight data. Lab-based instruments based on flame ionization detection (FID) techniques are unsuitable for in-flight use. However, a special Rosemount Analytical MLT 2 multi-component gas analyzer with two non-dispersive infrared (NDIR) benches in parallel, from Emerson Process Management, is helping overcome that obstacle.

The rugged design of the device allows it to withstand flight rigors and provide accurate, real-time in-flight flammability (hydrocarbon) data from the aircraft fuel tanks. It gave consistent readings when compared to typical FID detectors. The analyzer measured hydrocarbons as 2% propane equivalent with an accuracy ofing conditions.

To meet FAA needs, Rosemount modified the analyzer to control the temperature of the sample compartment up to 120 °C to eliminate the chance of jet fuel condensation. The device can also be continuously purged for safety purposes. Its successful application to in-flight jet fuel monitoring has led the FAA to order a second unit.

MLT Series of NGA 2000 analyzers offers multi-component, multi-method analysis using infrared, ultraviolet, thermal conductivity, paramagnetic, and electrochemical oxygen sensor technologies. The MLT 2 gas analyzer measures up to five gas components and can be configured as a stand-alone unit, a system control analyzer with front panel display and keypad, or an analyzer module.
