  • How molecular sieve DESICCANT is used for oxygen generation?

    Molecular sieves are basically three dimensional aluminosilicate that contains cavities inside the crystal. Through various channels these cavities are interconnected with each other. These channels are called pores. All the pores have an exact diameter which is uniform. This diameter plays a very crucial role in the application of these zeolites. This means that the molecules which have a ...

  • How do pressure swing adsorption nitrogen generators work?

    Adsorption is a gas separation process whereby the gas molecules adhere to a surface when under pressure. Adsorption allows for the ability to separate specific gasses, such as nitrogen, from compressed air by selecting an adsorbent material which unwanted gases more readily diffuse into. In the case of air-to-nitrogen separation, compressed air is passed through a cylinder containing a Carbon ...

  • Determination and justification of the reference scenarios and associated source terms for emergency planning in Switzerland

    For the purpose of planning emergency countermeasures in a nuclear accident, realistic reference scenarios were defined on the basis of general plant features. Three types of scenario cover the accident sequences expected to be the most probable. Time-scales and releases are identical for all Swiss Nuclear Power Plants (NPPs), although the plants differ in inventory, reactor type and age. The ...

  • Performance of Palladium Diffusers for Reliable Purification of Hydrogen

    Hydrogen generators are now becoming an essential component in many laboratories with greater gas consumption levels. Generators are considered to be preferable to cylinders, particularly because of the safety concerns about having high pressure hydrogen in the laboratory working environment. Hydrogen generator systems typically produce Hydrogen with a two-phase system. Hydrogen is first ...

  • Quantitative risk assessment across major hazard industries

    The terms QRA (Quantitative Risk assessment), PSA (Probabilistic Safety Assessment) and PRA (Probabilistic Risk Analysis) are used synonymously in different industries to describe various techniques for evaluating risk. Whilst quantification of risk for specific issues has been around for a long time, the grandfather of modern probabilistic assessment of the overall risk foran entire major hazard ...

  • Technical basis for off-site emergency planning in France

    Past experiences from nuclear accidents have clearly shown the importance of being prepared to manage these situations from public information to implementation of protective actions. This paper summarises the criteria used as a basis for off-site emergency planning and preparedness in France. The emergency response organisation, the general organisational scheme of actions, criteria for ...

  • In situ bioremediation of pentachlorophenol by dissloved oxygen injection

    ABSTRACT: In September of 1982 a faulty valve on a railroad tank car resulted in the accidental release of a wood treating solution containing pentachlorophenol. Subsequent investigations indicated that the wood treatment dip tank had also been a source of soil and ground water contamination. A ground water and product extraction system was installed soon after the rail car release, but after 13 ...

  • Comparing pesticide residues in Amish and commercially grown strawberries and spinach using QuEChERS, Various dSPE Sorbents, and GC-TOFMS

    Abstract QuEChERS extraction, dSPE cleanup, and GC-TOFMS analysis were used to assess pesticide levels in strawberries and spinach from both commercial and Amish growers. Various dSPE cleanup products were compared to determine which were most effective. Good recoveries were obtained for most pesticides; however, low recoveries were observed for some base-sensitive or planar compounds. ...

  • EU’s End-of-life Vehicle Rules Stuck in Neutral

    Against a backdrop of stagnant car sales and falling scrap metal prices, car makers and recyclers are gearing up for the implementation of the European Union’s end-of-life vehicle directive. Or are they? The European Union’s controversial end-of-life vehicle (ELV) directive comes into effect this month. But its passage from paper to practice appears to have stalled at a national level as car ...


  • Operator Strategies : Sorting Out the Plastic

    BETTER BUGS Ideas and products in the Better Bugs category attempt to affect the biological components and biochemistry of processes by altering the mix of microorganisms or enzymes present. After all, biology is the foundation of many, if not most, organics recycling systems. Pyrophiles: The first example of Better Bugs involves pyrophilic organisms, bugs that can take the heat. This example is ...
