  • Rerating Pipeline Pumps

    Pipeline operators transport billions of gallons of oil every year, and they are constantly looking at ways of improving efficiency and reducing costs. Depending on changing network demands, this might require managing an increase or decrease in flow rate in the pipeline, a change in pressure, or a pump upgrade to more efficient technology. Throughout the life of a pipeline, the process ...

  • Hydraulic Fracturing and the Environment Whitepaper - Analytical and Measuring Instruments

    The recovery of natural gas and oil from untraditional wells is necessary for the economic stability of the United States. Shale gas deposits are deep below the earth’s surface and recovery of gas is expensive and requires millions of gallons of water mixed with chemicals, known as "fracking solution". Most fracking solution stays underground or returns to the surface mixed with formation ...

  • Hydraulic Modelling in the Middle East and North Africa

    Water is under pressure in the Middle East and North Africa, a region which houses 4% of the world’s population but possesses only 1.4% of global water resources. A naturally scarce resource at the best of times faces increasing demand from a growing population with high expectations of water quality, supply and treatment. At the same time, the price of water fails to reflect the true cost of ...

  • Evaluation of uncertainties in system thermal-hydraulic calculations and key applications by the CIAU method

    The evaluation of uncertainty is a necessary supplement to Best Estimate (BE) calculations that are performed to understand accident scenarios in water-cooled nuclear reactors. The need comes from the imperfection of computational tools, on the one side, and from the interest in using such a tool to get more precise evaluation of safety margins, on the other. In the present paper, the approaches ...
