  • Performance and mechanism of anaerobic biotrickling filter for removal of sulfite, sulfate, and hydrosulfite

    A biotrickling filter (BTF) was designed for removal of sulfite (SO32−), sulfate (SO42−), and hydrosulfite (HSO−3) produced from flue gas adsorbent during dual-alkali flue gas desulfurization. With an SO32− concentration of 0.89 g-S/(L packing), BTF could completely remove SO32− within 3 h with an ...

  • Pollution monitoring in Cement Industry

    The rising use of waste based fuels in the cement industry, both for economic and Environmental objectives, combined with the strengthening of air emission regulations around the world is pushing many operators to face a wider list of pollutants to monitor this, with associated costs. The design of appropriate solutions meeting local regulation is the key to maximize the cost benefit of the fuel ...

    layer

    Quantum dot infrared photodetectors (QDIPs) have been shown to be a key technology in broad infrared wavelength (3-12 µm) detection due to their potential for normal incidence operation, low dark current density and higher temperature operation. In our research, we have been investigating infrared detectors based on intersubband transitions in a novel InAs/In0.15Ga ...

  • PureAire Combines Oxygen and CO2 Sensors to provide a Dual Gas Monitor to the Marketplace

    As a recognized leader in O2 safety monitoring, PureAire recently explored the need for an O2 monitor where carbon dioxide is used. There are four key cryogenic gases; nitrogen, helium, argon, and carbon dioxide (CO2), which can create an oxygen deficient atmosphere. Material Safety Data Sheets (MSDS) covering cryogenic gases cite that a cryogenic leak can create an unsafe ...
