  • Analysing the effects on the atmosphere of exergy changes due to exhaust-gas emissions

    The exergy change of the surroundings of exhaust-gas emitting ports, and its probable effects on the atmosphere, are investigated and the current stable state changing point of the atmosphere is determined. The potential for doing work is described and the effects of the amount of exhaust gas on the atmosphere are studied through calculation and analysis of an exergy-change function, which is ...

  • Molecular Beam Gas Analysis with Hiden Analytical

    Molecular beam mass spectrometry (MBMS) is used for quantitative gas analysis of reactive species and intermediates formed in various processes. Gas phase intermediates are sampled from reaction chambers using a differentially-pumped inlet, which forms a molecular beam of radicals, ions, polymers, or clusters. This is directed through a vacuum chamber and onto an ion detector. Due to the ...

  • `Applying Proper Dispersion Models for Industrial Accidental Releases,` presented at the 2004 AWMA annual conference

    Abstract Even though many industrial facilities have put extra efforts to prevent accidental releases of active and inactive chemicals from processes or storage, accidental releases do happen from time to time due to many reasons. Federal and state regulations require industrial facilities to evaluate and report the impacts of potential accidental releases in terms of distances to ...

  • Mass Flow Control in Bioreactors - Case study

    Vogtlin mass flow controllers are an excellent tool for precise control of gas flows in bioreactors. Bio reactors are used for critical and delicate processes where mass flow control of relevant gases need to be reliable, repeatable and flexible. For example, the dissolved oxygen needs to be carefully controlled to obtain repeatable pH control and volumes of fermentation gases like CO and H2 ...
