| A Multi-Sensor Approach for Monitoring River Chemical Tank Barge Emissions |

Monitoring for tank barge emissions to locate leaking barges and fix them, as well as determine or verify barge contents, must be cost effective and accurate. The use of field-deployable infrared spectrometers and open-path and passive devices, together with specialized thermal imaging cameras, has proven effective for locating leaking barges, determining the chemical(s) being released, and quantifying the emissions, defined as calculating the mass of the release per unit time. FTIR spectrometers were deployed in a radial plume mapping configuration to measure area emissions from the barges. Emissions also were measured at the source of the leak (e.g., barge hatch covers) using passive FTIR spectroscopy and specialized thermal imaging cameras that observed the plume as moving video. Verification of the remote sensing measurements was accomplished by measuring the leak flow rate using a leaking component encapsulation technique and by chemical analysis of canister samples in the laboratory. This presentation describes the findings of the study and the implications to port security applications. |
