  • A comparative study on the NH
    gas-sensing properties of ZnO, SnO
    , and WO

    In this work, a large quantity of ZnO, SnO2 and WO3 nanowires (NWs) was successfully synthesised by simple and efficient methods. Their morphology and microstructure were characterised by FE-SEM, TEM, XRD, PL, and Raman. The NH3 gas-sensing ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • Suddenly greenhouse gas regulations

    FROM a whisper to a scream, from 0 to 60 in 4 seconds or less, whether you prefer music metaphors or car metaphors, all of a sudden it seems that regulation of greenhouse gases (GHGs) is about to descend upon us. My reading list on the plane today includes the new U.S. Environmental Protection Agency GHG reporting requirements, a draft protocol from the California Climate Action Registry (CCAR) ...

  • Theory, Modeling, and Measurements of Gas Plumes

    Abstract Spectroscopic measurements of infrared CO2 transitions in gas plumes are reported, and evaluated for their potential to yield a reliable remote sensing technique for determination of plume temperature. Measurements were made on two types of plumes: a sideways-directed plume from a vehicle exhaust, and a stack plume from a propane-burning portable plume generator. Modeling of CO2 ...

  • Gas detector communication technology for offshore oil and gas platforms

    In few applications is safety as important as on offshore oil and gas platforms. Explosive hazards from hydrocarbon gases and vapours are an ever-present risk, whilst toxic hydrogen sulphide gas and depleted oxygen environments can pose significant risks to personnel. Gas detectors are therefore essential to provide dependable early warning of gas hazards. Gas detectors are permanently installed ...

  • How the EPA’s new oil and gas standards will reduce greenhouse gas emissions

    The U.S. Environmental Protection Agency recently issued final rules to reduce air pollution at natural gas wells and other sources in the oil and gas industry. The rules—a New Source Performance Standard (NSPS) for volatile organic compounds (VOCs) and National Emissions Standards for hazardous air ...
