  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • Sustainable Biorefineries: An Important Research Topic

    In recent years, substantial steps into the transition towards a biobased economy have been taken in order to reduce the reliance on imported oil and the emission of greenhouse gases.  As far as Europe is concerned, Sweden, home to theEUBCE 2017 in Stockholm, has been very successful in decoupling GHG emissions from economic growth: from 2000 to 2012, ...

  • Why Are CHP Closing All Over The World?

    Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use ...

  • Life Among The Heavy Metals

    Authors in scientific and applied works interpret the meaning of the concept "heavy metals" in different ways. Today, they include more than 40 chemical elements with an atomic mass of more than 50 atomic units. An important role in the determination of heavy metals is played by the following conditions: their high toxicity in relatively low concentrations, and the ability to bioaccumulation. ...

  • Oil in Power Plant Wastewater

    The water is from the operations of a steam power plant located in the Bahamas. The water samples were taken from the Unit 31 (lower oil content) and Tank #3 (a higher oil content). The samples were tested and it was found through the jartesting procedures that the Floccin K was the best choice for floc size and water clarity. The Unit 31 was dosed at 0.5 gram in 1,000 ml and the Tank # 3 water ...

  • The Future of Nuclear Power Plants

    With the blast of the French nuclear power plant a few weeks ago, safety of nuclear power plant designs has fallen under more scrutiny. Although according to sources the blast took place in the turbine hall and no nuclear leak was found, this event has brought more attention to improved design and operation standards. Following the incident earlier this month Toshiba, a Japanese ...

  • EDI for Power Plants -- Importance of silica

    Power plants use high purity water to drive steam turbines. Cogeneration plants are highly efficient, using both exhaust turbines and high pressure steam turbines. In the 1960's, boilers operated at 450C (840F) and 4MPa (40 atmospheres). Today's leading edge boilers operate at 620C (1150F) and 30MPa (300 ...

  • Exergoeconomic evaluation of a geothermal power plant

    In this study, exergy and exergoeconomic analyses of the Dora II geothermal power plant (DGPP) with 9.5 MW net power output are carried out by using real thermodynamic and cost data. The exergetic efficiency of this plant is calculated to be 29.6%. The highest exergy destruction rate among the DGPP components occurs in the cooling towers followed by the turbines, vaporisers, preheaters and pumps. ...

  • 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 ...
