  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • Economics of tiny thermal power plants

    Thermal power plants is the main source of energy and electricity in India and almost all countries of the world. Most of the giant thermal power plants have capacity of 500MW to 1000 MW. Investment in such giant thermal power plants is Rs 100 million per MW including transmission lines and distribution lines. ( 60 rupees = 1 US$, MW=1000KW). So 1000MW thermal power plant costs Rs 100 million/MW ...

  • Invasion of the non-indigenous nuisance mussel, Limnoperna fortunei, into water supply facilities in Japan

    The aquatic nuisance mussel, Limnoperna fortunei, arrived in Japan before 1987 possibly with the Asian clam imported as food from mainland China. Now the mussel’s distribution has spread to two river systems in central Japan. Water authorities reported several cases of damage caused by L. fortunei. Most cases of damage were caused by dead mussels clogging small diameter pipes for raw water ...

  • Integration of an analytic element model in a stochastic analysis of infiltration into a complex unconfined aquifer system

    ABSTRACT A hydrologic model based on the Analytic Elements Method (AEM) has been developed for a phreatic aquifer in the General Separations Area (GSA), of the Savannah River Site (SRS), South Carolina, USA. The AEM is a semi-analytical method that relies on the superposition of individual closed-form solutions of elements representing the main hydrologic features of a site. Our study adopts ...

  • Oil and water don`t mix

    Small spots of motor oil on your driveway look tacky enough. Leaks of hydraulic oil from the hydro turbine of a big pumped-storage plant are not only more noticeable, but they also could end up in the facility's sump or in its reservoir, as well. At the Blenheim-Gilboa Pumped Storage Power Project in New York's Catskill Mountains, there's another reason leaks are unacceptable. The New York Power ...

  • A Review of Cavitation-Erosion Resistant Weld Surfacing Alloys for Hydroturbines

    AbstractAn improved weld surfacing alloy has been developed and tested to resist cavitation-erosion in hydroturbines. Typical wear characteristics experienced in laboratory testing has been correlated to actual service conditions. A metallurgical evaluation shows that a high strain, work hardening austenitic stainless steel produces superior resistance to cavitational erosion. Several industrial ...

  • Hydroflo diaphragm pumps help reduce boiler corrosion and maintenance costs

    ABTCo, located in Alpena, Michigan, is a decorative wood paneling producer using three boilers to generate 7 MW of electricity – half the power needed in the plant plus steam for pulp processing. As in many boiler operations, the main enemy is corrosion, which can destroy system components and lead to boiler failure. Although internal boiler surfaces are protected by a film of magnetic ...

  • Port of Antwerp, Belgium

    The Port of Antwerp is a famous cargo handling port but is also only 300m from the historic city center, attracting hundreds of thousands of visitors every year. The Port needed to keep their waters clear of unsightly llitter and debris. Also, as a developing cruise port it handles 14,000 sailings per year to over 800 overseas destinations, and floating debris was causing a risk to navigation. ...


  • Viscous Pumping in Focus

    The performance of a pump is influenced when it handles viscous fluids such as crude oil. For the configuration and design of pumps, this is key. In the industry, pump performance curves are developed by testing with water at temperatures around 25°C and corrected to a specific gravity of one. Engineers use this standard so that they have comparable measurement values around the ...
