Download or read book Compressors and Compressed Air Systems written by A. Bhatia and published by CreateSpace. This book was released on 2014-12-06 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compressed air has many applications in industry. Delivering compressed air to a manufacturing facility is an expensive operation and it requires costly equipment that consumes significant amounts of electricity and needs frequent maintenance. Roughly 80 to 90 percent of the electricity used to operate compressed air systems is converted to low-temperature waste heat. This lost energy can quickly add up, each year costing individual facilities as much as double the purchase and installation cost (first-cost) of the entire system. The ideal time to think about your compressed air system is before it is installed.Air Compressors deserve independent treatment due to many reasons. There is a wider choice of different types of compressor designs each operating at different efficiencies and suitable for specific application. The type of compressor decided upon has direct implications on the lifetime energy costs. Also the decision as to a single compressor of large capacity versus multi-compressor installation where each compressor has a smaller capacity than the demand influences the possible energy savings considerably. This 6 -hour Quick Book Course provides comprehensive information on the compressed air systems. This course is relevant to anyone needing to know more about compressed air production and use, relevant health and safety issues, legislation and energy efficiency. Previous knowledge of the subject is not required.The book includes a multiple type quiz comprising 30 questions at the end.

Download or read book Handbook of Compressed Gases written by Compressed Gas Association, Inc. and published by Springer Science & Business Media. This book was released on 1999-06-30 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the field of compressed gases and related equipment, there is an expanding core of essential knowledge that people handling and using these materials should be familiar with or should know where to find. The focus ofthis book concerns the properties and the accepted means oftransportation, storage, and handlingofcompressed gases. This handbook is simultaneously intended as an overview ofthe subject and a source ofsupplementary information. It is also intended to serve as a guide to perti nent federal regulatory requirements and published standards of the Compressed Gas Association and other standards-developing organizations. The Association advises readers that the CGA technical publications remain the official statement ofpolicy on a particular matter. Reference is made throughout this text to the numerous technical publications published by the Compressed Gas Association. Some ofthese publications have been incorporated by reference into federal, state, provincial, and local regulations. Since the CGA publications are reviewed on a periodic basis, whenever the textofthis handbook conflicts with corresponding information in the CGA technical pamphlets, the most recently printed material shall take precedence.

Download or read book Steady State and Time Dependent Compressed Air Energy Storage Model Validated with Huntorf Operational Data and Investigation of Hydrogen Options for a Sustainable Energy Supply written by Friederike Kaiser and published by Cuvillier Verlag. This book was released on 2020-12-17 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind power and photovoltaic energy play a significant role in sustainable energy systems. However, these two renewable energy sources do not generate electrical energy on demand and are subject to natural fluctuations. Thus, the need for compensatory measures arises. Compressed air energy storage power plants (CAES) are a possible solution to providing negative and positive control energy in the electric grid. However, in contrast to other energy storage devices such as pumped hydro energy storage or batteries, the storage medium compressed air hardly contains any energy (or more precisely: enthalpy). Yet, compressed air storage allows the operation of highly efficient gas turbines, which are not only particularly fast available but also achieve better efficiency than combined cycle power plants used today, as illustrated by the example of the modern gas and steam power plant Irsching with ηtc = 60%from 2011 compared to the 20 years older McIntosh CAES with ηtc = 82.4 %. In this thesis, the calculation methods for the thermodynamics of the CAES process are presented and validated by measured data from the operations of the CAES power plant Huntorf. Both the steady state and the dynamic (time-dependent) analyses of the process take place. The characteristic value efficiency is discussed in detail, since numerous different interpretations for CAES exist in the literature. A new calculation method for the electric energy storage efficiency is presented, and a method for the calculation of an economically equivalent electricity storage efficiency is developed. Consideration is given to the transformation of the CAES process into a hydrogen-driven and, thus, greenhouse gas-free process. Finally, a model CAES system is tested in a 100 % renewable model environment. Consequently, it can be stated that in the steady-state thermodynamic calculation in particular, the consideration of realistic isentropic efficiencies of compressors and turbines is essential to correctly estimate the characteristic values of the process. Furthermore, a steadystate view should always be accompanied by dynamic considerations, since some process characteristics are always time-dependent. The simulation shows that by mapping transient operating conditions, the overall efficiency of the system must be corrected downwards. Nevertheless, in the model environment of a 100 % renewable energy system, it has been shown that a CAES is a useful addition that can provide long-term energy storage.
