  • Surface reaction and transport kinetics of hydrogen through palladium-based membranes under gas co-existing with hydrogen atmospheres

    In order to understand how gas co-existing with hydrogen affects the hydrogen permeability of a silver 23wt%-palladium membrane, the surface reaction of hydrogen was evaluated from the continuity of the surface reaction rate and the bulk diffusion flux of hydrogen based on the results of hydrogen-permeation measurements. The interference effect of the co-existing species was quantified as a ...

  • Lab Gas Price Bulletin November 2018

    A major gas company has increased the gas price for hydrogen and nitrogen gases in North America. This will have a knock-on effect for laboratories who buy nitrogen to supply their instruments. Labs can avoid the gas price increases by replacing their bulk supply with a nitrogen generator. On the 1st of October Air Products increased gas prices for liquid nitrogen, as well as increasing ...

  • Simplified method for quantifying theoretical underestimation of chamber-based trace gas fluxes

    Received for publication June 19, 2009. Closed chambers used to measure soil-atmosphere exchange of trace gases including nitrous oxide (N2O) and carbon dioxide (CO2) generate errors due to suppression of the gas concentration gradient at the soil-atmosphere interface. A method is described here for estimating the magnitude of flux underestimation arising from chamber deployment. The technique is ...

  • Analysis of key trends and drivers in greenhouse gas emissions in the EU between 1990 and 2014

    1 GHG emissions in 2014 compared to 2013 1.1 Summary (last year) Total GHG emissions (excluding LULUCF) decreased by 185 million tonnes, or 4.1% compared to 20132 to reach their lowest level in 2014 (4282 Mt CO2 eq.). This significant decrease in emissions in 2014 came with an increase in GDP of 1.4 %. This resulted in a lower GHG-emission intensity of GDP in the EU ...

  • Conservation through water reuse: Experiences from the Santa Ana Pueblo

    The Situation: The Tamayamé, the Native American Tribal members of the Santa Ana Pueblo, north of Albuquerque, NM, are committed to natural resource conservation and future economic development. In the late 1990s, they built a water reclamation facility and began reusing treated effluent to irrigate the Pueblo’s golf course. Although they were pleased with the safety and ...

  • MIOX offers another sanitizing alternative

    It was with great interest that I read your article titled “Drinking It In”(February 2007). The story specifically mentions filtrations and UV as two examples of water technologies used in the aquatics business. I would like to bring to your readers’ attention another promising technology that got its start in the municipal water market. Chlorine-based mixed oxidants originally were developed for ...

  • Properties and Behavior of Fuels

    Fuel contaminants are generally nonhalogenated. Information presented for nonhalogenated VOCs and nonhalogenated SVOCs may also be appropriate for many of the fuel contaminants presented in this subsection. Contamination by fuel contaminants in the unsaturated zone exists in four phases: vapor in the pore spaces; sorbed to subsurface solids; dissolved in water; or as NAPL. The nature and extent ...

  • Temporary vehicle refuelling station for local authority demonstration

    All UK cities have to work towards achieving the Government’s targets for reduction of greenhouse gas emissions as part of a Low Emissions Strategy. In Spring 2010, Sheffield became one of the very first cities in the UK to use a mobile gas filling station to fuel commercial vehicles. This was the result of a lease agreement between Chesterfield BioGas Ltd and the City Council, for ...

  • Gentle emptying of powder tankers

    Gericke of Switzerland has successfully designed a pneumatic conveying system for discharging delicate powders and granulates from road tankers, and has also introduced a similar system for unloading product from dry bulk container liners. Several other recent pneumatic conveying developments are also itemised. Retention of powder characteristics such as bulk density and particle size is ...

  • ClorTec® An Operational Profile of a Pennsylvania Water Treatment Plant’s On-site Hypochlorite Generating System

    For more than 30 years, on-site generation of sodium hypochlorite has been a key process in water treatment for municipal and industrial applications. The benefits of the on-site generation process over chlorine gas and bulk hypochlorite have been well documented and include: Eliminate bulk storage of hazardous chemicals Reduce risk to plant personnel because of drastically eliminate hazardous ...

  • Properties and Behavior of Halogenated VOCs

    An important consideration when evaluating a remedy is whether the compound is halogenated or nonhalogenated. A halogenated compound is one onto which a halogen (e.g., fluorine, chlorine, bromine, or iodine) has been attached. The nature of the halogen bond and the halogen itself can significantly affect performance of a technology or require more extensive treatment than for nonhalogenated ...

  • Properties and Behavior of Nonhalogenated VOC`s

    An important consideration when evaluating a remedy is whether the compound is nonhalogenated or halogenated. A nonhalogenated compound is one which does not have a halogen (e.g., fluorine, chlorine, bromine, or iodine) attached to it. The vendor of the technology being evaluated must be informed whether the compounds to be treated are nonhalogenated or halogenated. In most instances, the vendor ...

  • Nitrogen Tank or Cryogenic Dewar? Not Sure Where they are Installed? Here`s the List!

    Liquid nitrogen is used in a broad range of industries, from steelmaking and pharmaceutical to health care and ceramics. The inert gas is also used in laboratories, breweries, fine cooking, and more. Wherever liquid nitrogen is used, it must be stored securely so as not to mingle with air. Learn why nitrogen must be so carefully contained and where and how N2 gas is ...

  • HM-218D – The US Moves Forward on Gasohol and Other Updates

    On January 28, the US DOT passed Amendment HM-218D. This final rule adopts various updates and amendments to the Hazardous Materials Regulations (HMR) of 49 CFR, and is intended to provide relief to industry by clarifying and, in some cases, relaxing certain requirements. A major goal of this amendment is to help the environment by simplifying the shipment of Gasohol, a blend of gasoline with ...
