Energy efficient utilization

Kojima, K., Principle of Efficient Energy Utilization, Chapter 8, Baifukan, Tokyo, 2004. [Pg.474]

II. Campbell H, et al. Efficient energy utilization and environmental issues applied to power planning. Energy Policy. 2011 39(6) 3630-7. [Pg.30]

The Castner process is characterized by more efficient energy utilization and by more uniform graphitization compared with the Acheson process. Disadvantageous is the more complex furnace construction and restrictions concerning the dimensions of the carbon articles. [Pg.510]

Technical Aspects of Efficient Energy Utilization," American Physical Society, Summer Study, 1974. [Pg.142]

Mercury has a high vapor pressure at the normal cell operating conditions hence it is always found in the reaction products. Although the mercury is almost completely recovered and returned to the process, environmental problems associated with mercury, combined with the less efficient energy utilization compared to the modem membrane cell process, has effectively stopped the building of new mercury cell plants. Furthermore, in the 1990s, membrane cells will most likely replace most of the present mercury cells. For details related to mercury cells, see references 8 and 16 and general references. [Pg.488]

Because of the high energy input required for many major chemical Efficient utilization of processes the chemical industry has been in the forefront of the development energy and application of efficient energy utilization techniques. [Pg.245]

V.Reversibility as a concept, however, is of paramount importance in thermodynamic applications, such as in the area of efficient energy utilization, as we will see in later Chapters. [Pg.14]

The feasibility of processes and the efficient energy utilization in carrying them out represent the original objectives of thermodynamics and the reason for its name. Actually, the second objective has been traditionally of interest to power engineers, mostly mechanical, while chemical engineers paid only lip service to it, when energy cost was very low. [Pg.21]

The drastic increase in energy cost following the Oil Embargo of 1973, however, and its impact on the product cost of the chemical and petroleum industries, made the subject of efficient energy utilization a major concern of chemical engineers as well. [Pg.21]

Examples 1.6 and 1.9 deal with the problem of energy use, the second with efficient energy utilization. [Pg.25]

Our discussion of the laws of thermodynamics in the 2nd and 3rd Chapters indicates that their application, combined with knowledge of thermophysical properties, provides for the evaluation of the feasibility of processes and, as we will see in the next Chapter, for the efficient energy utilization, i.e. the first objective of chemical engineering thermodynamics. [Pg.144]

Until the early 1970 s chemical engineers did not pay much attention to efficient energy utilization. Energy was very cheap, at least in the United States, and its impact on plant operating cost relatively small. [Pg.155]

Efficient energy utilization, i.e. energy conservation, became consequently a factor of paramount importance in the Chemical and Petroleum industries.Thus the U.S. Chemical industry committed to, and achieved, a 1/3 reduction in energy consumption by the early 1980 s. [Pg.155]

Efficient energy utilization - energy conservation - is a very broad and complex subject to be covered in the limited amount of space allocated here. Our objective, therefore, is to focus attention to the problem and... [Pg.156]

We will start with establishing the standard of excellence for efficient energy utilization the concept of ideal work. When this is reached, no further energy conservation is possible. [Pg.158]

We proceed with a presentation of the quantitative criteria used to determine the degree of efficient energy utilization in a given process first and second law efficiencies, followed by a brief description of one of the methods used to obtain increased such efficiencies in the use of thermal energy. Cogeneration. We demonstrate the energy savings achieved and discuss the limitations involved and the ways around them. [Pg.158]

We discuss next how exergy is evaluated, and then how it is used in establishing the yardstick of efficient energy utilization, the second law efficiency. [Pg.166]

In the next Section we will use exergy to establish the yardstick for measuring the degree of efficient energy utilization in a given process, the second law efficiency. The first law efficiency, is also Introduced for comparison purposes. [Pg.170]
