Download or read book Reaction Engineering for Pollution Prevention written by R.P. Hesketh and published by Elsevier. This book was released on 2000-02-09 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book defines environmental reaction engineering principles, including reactor design, for the development of processes that provide an environmental benefit. With regard to pollution prevention, the focus is primarily on new reaction and reactor technologies that minimize the production of undesirable side-products (pollutants), but the use of reaction engineering as a means of treating wastes that are produced through other means is also considered.First is a section on environmentally benign combustion. The three papers discuss methods of reducing the formation of PAHs and NOx, as well as other environmentally sensitive combustion products. The next section contains a collection of contributions that involve the use of a catalyst to support the reaction. Following this is a section on the use of supercritical fluid solvents as environmentally friendly media for chemical reactions. Finally, a series of papers is presented in which novel reactor designs are utilized to obtain product yields not possible in conventional reactor systems. These include the use of reactor-absorber systems, reactive distillation, and reactive membranes. The book concludes with a chapter contributed by the editors which discusses the educational aspects of pollution prevention. It is necessary for future generations of engineers to be trained to design processes that are inherently environmentally benign. This chapter assembles resource materials for educators which will spark the creative instincts of the researchers using the materials contained within this book to develop new resources for pollution prevention education. The broad spectrum of topics included in this book indicates the diversity of this area, and the vibrant nature of the ongoing research. The possibilities of producing desirable products without the formation of waste byproducts are bounded only by the creativity of the reaction engineer.

Book excerpt: Legislation introduced in the 111th and 110th Congresses invokes the symbolism of the Manhattan project of the 1940s and the Apollo program of the 1960s to frame proposals for large-scale energy policy initiatives that include developing CCS technology. [...] Arguably the most economic and technologically challenging part of the carbon capture and sequestration (CCS) equation is capturing the carbon and preparing it for transport and storage.5 Depending on site-specific conditions, the capture component of a CCS system can be the dominant cost-variable, and the component that could be improved most dramatically by further technological advancement. [...] Second, the paper examines the role of government in developing that technology, both in terms of creating a market for carbon capture technology and encouraging development of the technology. [...] A recent study by the Massachusetts Institute of Technology (MIT) estimated the efficiency losses from the installation of MEA from 25%-28% for new construction and 36%- 42% for retrofit on an existing plant.9 This loss of efficiency comes in addition to the necessary capital and operations and maintenance cost of the equipment and reagents. [...] The details of this "oxy-fuel" process are still being refined, but generally, from the boiler the exhaust gas is cleaned of conventional pollutants (SO2, NOx, and particulates) and some of the gases recycled to the boiler to control the higher temperature resulting from coal combustion with pure oxygen.

This book was released on 2011-02-26 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxy-fuel combustion is currently considered to be one of the major technologies for carbon dioxide (CO2) capture in power plants. The advantages of using oxygen (O2) instead of air for combustion include a CO2-enriched flue gas that is ready for sequestration following purification and low NOx emissions. This simple and elegant technology has attracted considerable attention since the late 1990s, rapidly developing from pilot-scale testing to industrial demonstration. Challenges remain, as O2 supply and CO2 capture create significant energy penalties that must be reduced through overall system optimisation and the development of new processes.Oxy-fuel combustion for power generation and carbon dioxide (CO2) capture comprehensively reviews the fundamental principles and development of oxy-fuel combustion in fossil-fuel fired utility boilers. Following a foreword by Professor János M. Beér, the book opens with an overview of oxy-fuel combustion technology and its role in a carbon-constrained environment. Part one introduces oxy-fuel combustion further, with a chapter comparing the economics of oxy-fuel vs. post-/pre-combustion CO2 capture, followed by chapters on plant operation, industrial scale demonstrations, and circulating fluidized bed combustion. Part two critically reviews oxy-fuel combustion fundamentals, such as ignition and flame stability, burner design, emissions and heat transfer characteristics, concluding with chapters on O2 production and CO2 compression and purification technologies. Finally, part three explores advanced concepts and developments, such as near-zero flue gas recycle and high-pressure systems, as well as chemical looping combustion and utilisation of gaseous fuel.With its distinguished editor and internationally renowned contributors, Oxy-fuel combustion for power generation and carbon dioxide (CO2) capture provides a rich resource for power plant designers, operators, and engineers, as well as academics and researchers in the field.

Download or read book Tests to Produce and Recover Carbon Dioxide by Burning Coal in Oxygen and Recycled Flue Gas written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were conducted using a modified stoker-fired boiler (2.2 x 106 Btu/h) instrumented to examine the feasibility of producing and recovering carbon dioxide by burning coal in oxygen and recycled flue gas in a utility environment. The tests demonstrated that the boiler can be operated in the oxygen-blown/flue-gas-recirculation mode without any noticeable effects on coal combustion, heat delivery to the water, or the coal-feed or ash-handling systems. Pretest calculations showed that a feasible set of operating parameters for a carbon-dioxide-producing combustor system tightly sealed against air infiltration and containing no more than about 5% O2 (dry basis) at the furnace exit would be a flue-gas recycling ratio between 0.6 and 0.7 and an oxygen feed rate of 1.17 g-moles per g-atom of carbon, yielding an exhaust gas composition (wet basis) of approximately 46.9% CO2, 50.6% H2O, and 2.5% O2. This composition corresponds to a product gas containing 95% CO2 and 5% O2 (dry basis). However, because air leaked into the test combustor and the flue-gas handling system, the highest carbon dioxide concentration achieved in the exhaust gas was 48.5% (dry basis). Major sources of inleakage were the furnace brickwork, the gas-handling system, and the coal-feed and ash-extraction systems. 40 figs.

Book Synopsis Formation and Removal of SOx and NOx in Pressurized Oxy-fuel Coal Combustion by : Muhammad Jahangir Malik
Download or read book Formation and Removal of SOx and NOx in Pressurized Oxy-fuel Coal Combustion written by Muhammad Jahangir Malik and published by . This book was released on 2019 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing concerns over greenhouse gas emissions have driven extensive research in carbon capture, storage and sequestration. Oxy-fuel combustion is a promising technology in CO2 capture, as the combustion products consists primarily of CO2 and H2O with contaminants like NOx and SOx. More recently, oxy-fuel combustion under pressurized conditions has gained attention due to its overall higher net efficiency, while decreasing the auxiliary power consumption in the process. The need for a better understanding of the coal combustion in oxy-fuel conditions under elevated pressures and the formation of SOx and NOx in such conditions inspired this research project. In this thesis, the effect of pressurized oxy-fuel combustion on SOx and NOx formation from coal combustion and their removal from the flue gas was investigated. The combustion modelling for lignite coal was conducted in ANSYS Fluent, under oxy-fuel environment at atmospheric pressure and elevated pressures (5 atm, 10 atm, 15 atm). The results showed an increase in SO3 formation and rapid decrease in NO in the flue gas as the pressure was increased in the combustor. At 15 atm, the NOx emissions were found to be below 100 ppm, which is an acceptable concentration of NOx for CO2 transport and storage. In order to investigate the influence of pressure on SOx and NOx in the flue gas in the post-combustion zone, the system was subjected to a temperature profile representative of an actual plant boiler, where the residence time is around 2 seconds. The results showed that the rate of SO2 and NO oxidation to SO3 and NO2, respectively, were influenced by the rate of temperature decrease, and the effect of pressure was not as significant. It was observed that flue gas composition remained constant below 550 K, as all SO3 present in the flue gas converted to gaseous H2SO4. Lastly, simulations for SOx and NOx removal from flue gas via absorption were performed at 15 atm to purify the flue gas to meet the requirements for CO2 transportation. The results showed complete removal of SOx in the form of H2SO4 and SO42- and around 30% NOx removal, mostly in the form of HNO3. A sensitivity analysis was performed on the reflux ratio of liquid in the absorber and the results showed increased NOx removal at lower reflux ratio. The investigation helped conclude that pressurized oxy-fuel combustion results in lower SOx and NOx emissions, and require less sophisticated separation techniques to meet the pipeline threshold for CO2 transportation in storage and sequestration.

This book was released on 2011 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxy-coal combustion technology has great potential as one of the major CO2 capture technologies for power generation from coal. The distinguishing feature of oxy-coal combustion is that the oxygen source is a high concentration oxygen stream and the product flue gas consists primarily of CO2 and H20 with contaminants like NOx, SOx, and non-condensable gases like argon, oxygen and nitrogen. For carbon sequestration and Enhanced Oil Recovery (EOR) applications, pipeline transport standards as well as storage specifications impose concentration limits on these contaminants. These must be removed to ensure that the transported CO2-rich stream stays within specified limits to prevent aqueous phase separation, hydrate formation, and corrosion due to acids, water or oxygen. The purification process however constitutes additional energy consumption and lowers overall cycle efficiency. Purification options like traditional flue gas desulfurization (FGD), selective catalytic reduction (SCR), catalytic O2 consumption, packed bed adsorption and low temperature flash separation have been proposed. In this thesis, we develop a novel CO2 purification process model for oxy combustion systems that utilizes high-pressure reactive absorption columns for NOx and SOxrem oval and distillation strategies for noncondensable gas removal. This process results in significant cost savings and lower energy consumption compared to the traditional systems. We conduct a sensitivity analysis NOx and SOx removal system to determine the key performance parameters and based on the results present a modification to the base case that results in further cost and energy savings. Different strategies for the removal of non-condensable gases are developed and compared. This study also explores opportunities for integrating the CO2 purification unit (CPU) with the base cycle and the impacts of the different strategies on the overall oxy combustion cycle efficiency are presented. A cost analysis for the proposed purification process is also presented.
