  • Synthesis and characterization of a novel organic nitrate NDHP: Role of xanthine oxidoreductase-mediated nitric oxide formation

    Abstract In this report, we describe the synthesis and characterization of 1,3-bis(hexyloxy)propan-2-yl nitrate (NDHP), a novel organic mono nitrate. Using purified xanthine oxidoreductase (XOR), chemiluminescence and electron paramagnetic resonance (EPR) spectroscopy, we found that XOR catalyzes nitric oxide (NO) generation from NDHP under anaerobic conditions, and that thiols are not ...

  • Insitu analysis of ammonia slip and water vapor using a tunable diode laser for SCR/SNCR optimization and boiler tube surveillance in power plants

    ABSTRACT Environmental Regulations driven by the 1990 Clean Air Act require Power Plants to reduce NOx emissions. SCR's and SNCR's reduce NOx emission by injecting ammonia into the combustion flue gas. which ideally reacts with the NOx to form H?0 and Nj. The efficiency of the SCR SNCR is determined by monitoring the outlet for excess NH3. referred to as NH3 slip. The flue gas sample ...

  • Demonstration of an Ethane Spectrometer for Methane Source Identification

    ABSTRACT: Methane is an important greenhouse gas and tropospheric ozone precursor. Simultaneous observation of ethane with methane can help identify specific methane source types. Aerodyne Ethane-Mini spectrometers, employing recently available mid-infrared distributed feedback tunable diode lasers (DFB-TDL), provide 1 s ethane measurements with sub-ppb precision. In this work, an Ethane-Mini ...

  • RSD technology for MBTA bus fleet emissions

    Exhaust emissions from transit buses have long been a concern for air quality officials. Agencies have been investing millions of dollars in advanced and clean fuel technologies to reduce emissions from their bus fleets. Generally, the only information available about the emission characteristics of these vehicles comes from expensive engine- and chassis-dynomometer tests. Relatively little is ...

  • Risk evaluation of technology innovation in China's oil and gas industry

    Oil and gas industries are technology intensive and appropriate risk evaluation is necessary. The Chinese oil and gas industry is in the development phase, thus risk assessments and mitigation is more important than pushing technological innovation.
