Abstract Information :

The use of open-path fence-line air monitoring systems are becoming an attractive alternative to traditional point sampling devices for identifying emissions associated large scale pollution sources. However, critical gaps remain in the utility of this approach as gases such as hydrogen sulfide H2S have been difficult to detect employing open-path systems at concentrations measured by other methods. The paper presents the results of an evaluation of a new GasEyeTM open-path air monitoring system based on tunable laser that has been tested at the fence-line of an oil refinery in California. The system can be operated at sample path lengths over 1,000 meters, is capable of quantifying H2S, water, and methane in real-time, records the raw data spectra, and can be calibrated in the field using both sealed and flow-through gas cells. A summary of the data collected by the system during a six-month evaluation period of the technology will be discussed, including an evaluation of the systems detection capability, a discussion of advantages of this approach and a summary of the quality assurancequality control QAQC checks. In addition, a test plan for overall acceptance of the H2S system will be presented, which incorporates QAQC indicators associated with EPA Compendium Method TO-16.rnrnrnrn
