  • Ukraine spotlights German priority: energy switch

    The crisis in Ukraine has added an extra dose of uncertainty to German Chancellor Angela Merkel's biggest domestic project: shifting the country from nuclear to renewable energy sources. Merkel launched the drive to transition the country away from nuclear after Japan's 2011 Fukushima disaster. Since then, the "Energiewende" - roughly, "energy turnaround" - has created increasing headaches. Now, ...

  • Projected leaf area and flow rate - options and observed effects on gas exchange measurements with CIRAS-2

    From a practical and theoretical standpoint, the objective in using gas exchange technology is to capture representative plant/soil physiological data, holding instrument error to a minimum. A basic goal in this is to ensure that sampling reflects real responses to natural or imposed environmental variability (treatments). Whether from an observational or experimental approach, the physiological ...

  • Non-contacting solution for Plugged off flow meters in the oil patch - Case Study

    For years Petrobakken Energy Ltd. used inline turbine flow meters to track the flow rate of oil recycled to treaters. But with a high concentration of wax and sand in the oil, the turbine meters were quickly plugging off. The line had to be shut down at least once a day and the turbine flowmeters disassembled for cleaning. This was troublesome and expensive. Petrobakken knew there had to be a ...

  • Can a gas engine use diesel fuel with less pollution?

    Anyone concerned with rising oil prices and pollution from fossil fuel might like to know about a new technology, which addresses both problems. Its application will put an end to the days of sooty smoke seen from accelerating diesel trucks and buses. The ...


  • An artificial intelligence approach for optimizing pumping in sewer systems

    This paper presents details of a fuzzy logic system developed for the control of sewer pumping stations for energy costs savings. This is part of an ongoing collaborative project between Anglian Water and the University of Sheffield. The model rules and operation are developed for one representative pumping station in order to enable the identification of potential benefits and inhibitors to ...

  • A model for assessment of energy utilisation within an urban centre

    This paper presents development of a model for analysis of energy and exergy utilisation within an urban centre of Calgary, Canada. The analysis began with the detailed assessment of energy resource utilisation patterns and energy flows across six different energy consuming sectors, namely energy generation, residential, commercial, industrial, transportation and agricultural. For each sector, ...

  • Drying plastic resin pellets in injection- Molding & Extrusion processes case study

    Application Moisture concentrations are measured in the dry purge air used to remove moisture from a hopper containing plastic resin pellets used in injection-molding and extrusion processes. Problem Moisture contaminates the plastic resin pellets causing several quality problems in the finished plastic products. Moisture causes clear ...

  • 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 ...

  • Municipal waste water treatment plant case study

    A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...

  • Metal Coating Emission Control

    The use of regenerative thermal oxidizers is expanding into applications where they wouldn’t have been considered years ago, says Mike Scholz As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking ...

  • Common Treatment Technologies for Fuels in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate fuels in ground water. Treatability testing to characterize contaminant biodegradability and nutrient content may be needed for any biodegradation technology. A subsurface geologic characterization would be particularly important to characterize the migration of NAPLs. Recovery tests are usually necessary to design a ...

  • Project profile - Webb Consolidated Independent School Bruni, Texas arsenic treatment system

    Background Webb Consolidated Independent School District (Webb CISD) located in Bruni, Texas applied to the U.S. Environmental Protection Agency (USEPA) to participate in the arsenic treatment demonstration program for Round 2 and was selected. The school has a water-supply well which pumps water to a 12,000 gallon storage tank. Waterquality analyses revealed that arsenic concentrations ...

  • Crossville, TN, municipal drinking water

    The Situation: The City of Crossville, Tennessee, needed to address increasingly strict regulations on the use of gas chlorine to disinfect their community’s water.
