This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-dimensional, non-isothermal, pressure-driven dynamic model has been developed for a two-stage bubbling fluidized bed (BFB) adsorber-reactor for solid-sorbent carbon dioxide (CO2) capture using Aspen Custom Modeler® (ACM). The BFB model for the flow of gas through a continuous phase of downward moving solids considers three regions: emulsion, bubble, and cloud-wake. Both the upper and lower reactor stages are of overflow-type configuration, i.e., the solids leave from the top of each stage. In addition, dynamic models have been developed for the downcomer that transfers solids between the stages and the exit hopper that removes solids from the bottom of the bed. The models of all auxiliary equipment such as valves and gas distributor have been integrated with the main model of the two-stage adsorber reactor. Using the developed dynamic model, the transient responses of various process variables such as CO2 capture rate and flue gas outlet temperatures have been studied by simulating typical disturbances such as change in the temperature, flowrate, and composition of the incoming flue gas from pulverized coal-fired power plants. In control studies, the performance of a proportional-integral-derivative (PID) controller, feedback-augmented feedforward controller, and linear model predictive controller (LMPC) are evaluated for maintaining the overall CO2 capture rate at a desired level in the face of typical disturbances.

Book Synopsis Applied Engineering Statistics by : R. Russell Rhinehart
Download or read book Applied Engineering Statistics written by R. Russell Rhinehart and published by CRC Press. This book was released on 2021-11-02 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thoroughly updated throughout, this second edition will continue to be about the practicable methods of statistical applications for engineers, and as well for scientists and those in business. It remains a what-I-wish-I-had-known-when-starting-my-career compilation of techniques. Contrasting a mathematical and abstract orientation of many statistics texts, which expresses the science/math values of researchers, this book has its focus on the application to concrete examples and the interpretation of outcomes. Supporting application propriety, this book also presents the fundamental concepts, provides supporting derivation, and has frequent do and not-do notes. Key Features: Contains details of the computation for the examples. Includes new examples and exercises. Includes expanded topics supporting data analysis. The book is for upper-level undergraduate or graduate students in engineering, the hard sciences, or business programs. The intent is that the text would continue to be useful in professional life, and appropriate as a self-learning tool after graduation – whether in graduate school or in professional practice.

Book Synopsis Fluidized Bed Boilers by : Prabir Basu
Download or read book Fluidized Bed Boilers written by Prabir Basu and published by Elsevier. This book was released on 2013-10-22 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluidized Bed Boilers: Design and Application attempts to address the need for a single source of information covering all major areas of fluidized bed boiler design and operation. It is based on the International Workshop on Design and Operation of Atmospheric Pressure Fluidized Bed Boilers, organized by the Center for Energy Studies, Technical University of Nova Scotia in Halifax on 24-45 June 1983. The volume begins by presenting a simplified approach to the design of a fluidized bed boiler and an overview of problems in fluidized-bed combustion (FBC). These are followed by separate chapters on the equations and concepts needed to estimate key hydrodynamic parameters; the key factors and terms to be considered in selecting FBC for specific applications; and principles in the design of air distributors for a fluidized bed boiler. Subsequent chapters discuss heat transfer to surfaces in fluidized beds; the pollution control of fluidized bed combustion of solid fuels; and materials selection in atmospheric fluidized bed combustion systems. The final two chapters are devoted to applications. These include the operational and performance results of TVA’s 20-MW Atmospheric Fluidized Bed Combustion (AFBC) Pilot Plant in Kentucky; and the performance of Canada's first commercial FBC boiler plant, located at CFB Summerside, PEI.

Book Synopsis Gasification for Practical Applications by : Yongseung Yun
Download or read book Gasification for Practical Applications written by Yongseung Yun and published by BoD – Books on Demand. This book was released on 2012-10-24 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there were many books and papers that deal with gasification, there has been only a few practical book explaining the technology in actual application and the market situation in reality. Gasification is a key technology in converting coal, biomass, and wastes to useful high-value products. Until renewable energy can provide affordable energy hopefully by the year 2030, gasification can bridge the transition period by providing the clean liquid fuels, gas, and chemicals from the low grade feedstock. Gasification still needs many upgrades and technology breakthroughs. It remains in the niche market, not fully competitive in the major market of electricity generation, chemicals, and liquid fuels that are supplied from relatively cheap fossil fuels. The book provides the practical information for researchers and graduate students who want to review the current situation, to upgrade, and to bring in a new idea to the conventional gasification technologies.
Book Synopsis Fluid Dynamic of Pressurized Coal Gasifiers by :

Book excerpt: Pressurized, entrained gasification is a promising new technology for the clean and efficient combustion of coal. Its principle is to operate a coal gasifier at a high inlet gas velocity to increase the inflow of reactants, and at an elevated pressure to raise the overall efficiency of the process. Unfortunately, because of the extraordinary difficulties involved in performing measurements in hot, pressurized, high-velocity pilot plants, its fluid dynamics are largely unknown. Thus the designer cannot predict with certainty crucial phenomena like erosion, heat transfer and solid capture. In this context, we have conducted a study of the fluid dynamics of Pressurized Entrained Coal Gasifiers (PECGs). The idea was to simulate the flows in generic industrial PECGs using dimensional similitude. To this end, we employed a unique entrained gas-solid flow facility with the flexibility to recycle -rather than discard- gases other than air. By matching five dimensionless parameters, experiments employing plastic and glass powders fluidized with mixtures of sulfur hexafluoride, carbon dioxide, helium and air at ambient temperature and pressure achieved hydrodynamic similarity with generic high-temperature risers of variable scale operating at 1 and 8 atm. We interpreted our results in the upper riser using steady, fully developed momentum balances for the gas and solid phases. This analysis showed that, for a wide range of experiments, two parameters capture the dependence of the pressure gradients upon the ratio of the mean gas and solid mass flow rates. The first is the ratio of the mean particle slip and superficial gas velocities. The second represents spatial correlations between the radial profiles of interstitial gas velocity and voidage. Variations of the first with dimensionless parameters indicated that our'atmospheric' and'pressurized' experiments conformed to distinct viscous and inertial regimes. In this study, we established also that the descending velocity of particles clusters at the wall of a riser scales exclusively with the square root of the particle diameter and the gravitational acceleration. This observation showed that the dynamics of wall clusters is chiefly determined by inter-particle contacts. Because these clusters govern heat transfer at the wall, this conclusion has important consequences for modeling. These activities were conducted with Air Products & Chemicals, Inc., which was a member of a consortium that included Foster Wheeler and Deutsche Babcock Energie-und Umwelttechnik AG. At the completion of this work, the results have exceeded the expectations outlined in the original proposal. The present report summarizes these accomplishments, which have led to four publications, 13 presentations, several quarterly reports, and the support of three graduate students.
