Tungsten is a refractory metal with the highest melting point of all metals, which is considered as a promising candidate material for plasma-facing materials in the future fusion reactor. However, tungsten faces several challenges from intrinsic embrittlement, irradiation embrittlement and recrystallization embrittlement during the …
Therefore, an intensive effort is currently underway in the industry to identify energy saving measures to address these issues. It was outlined in U.S. Department of Energy and U.S. Energy Information Administration reports that current size reduction practices are highly inefficient (BCS, Incorporated, 2002, BCS, Incorporated, 2007).
A typical corn wet milling plant in the United States spends approximately $20 to $30 million per year on energy, making energy efficiency improvement an important way to reduce costs and increase predictable earnings, especially in …
Wastewater treatment plants (WWTPs) consume high amounts of energy which is mostly purchased from the grid. During the past years, many ongoing measures have taken place to analyze the possible solutions for both reducing the energy consumption and increasing the renewable energy production in the plants.
