Download or read book Carbon Management written by National Research Council and published by National Academies Press. This book was released on 2001-09-15 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Considerable international concerns exist about global climate change and its relationship to the growing use of fossil fuels. Carbon dioxide is released by chemical reactions that are employed to extract energy from fuels, and any regulatory policy limiting the amount of CO2 that could be released from sequestered sources or from energy-generating reactions will require substantial involvement of the chemical sciences and technology R&D community. Much of the public debate has been focused on the question of whether global climate change is occurring and, if so, whether it is anthropogenic, but these questions were outside the scope of the workshop, which instead focused on the question of how to respond to a possible national policy of carbon management. Previous discussion of the latter topic has focused on technological, economic, and ecological aspects and on earth science challenges, but the fundamental science has received little attention. This workshop was designed to gather information that could inform the Chemical Sciences Roundtable in its discussions of possible roles that the chemical sciences community might play in identifying and addressing underlying chemical questions.

Download or read book Studies in Advanced Oxy combustion Technologies written by Fei Xia and published by . This book was released on 2014 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2013, approximately 87 percent of the total world energy came from combustion sources. While combustion is of critical significance, it poses serious issues. The rapid increase in energy consumption, primarily from increased fossil fuel use, has raised strong concerns over the current energy infrastructure, the emissions of particulate matter, CO, SO2, and NOx, as well as global warming due to the emission of CO2. Improving combustion efficiency and reducing combustion emissions are essential. This dissertation focuses on two areas: (1) Computational fluid dynamics simulations of a novel burner design for a new oxy-fuel technology with relatively high efficiency and low emissions, and (2) numerical studies of flame structure and soot inception, interpreted in the carbon-to-oxygen atom ratio space for laminar diffusion flames. Part I. Oxy-fuel combustion is considered a promising technology for carbon capture, utilization, and storage (CCUS). One of the primary limitations on full-scale implementation of this technology is the significant increase in the cost of electricity due to a large reduction in plant efficiency and high capital costs. The fact that the CO2 captured must ultimately be pressurized for geo-sequestration or Enhanced Oil Recovery (EOR) enables pressurized oxy-combustion to be implemented at no net pumping cost because the energy to pump oxygen is comparable to that to pump CO2. At higher pressure the latent heat of condensation of the moisture in the flue gas can be utilized in the Rankine cycle, increasing the plant efficiency. A new pressurized oxy-combustion technology, namely staged, pressurized oxy-combustion (SPOC) has been developed in which the flue gas recycle is minimized by means of fuel-staged combustion. As determined through ASPEN Plus modeling, this process increases the net plant efficiency by more than 5 percentage points, compared to first-generation oxy-combustion plants. In the SPOC process, pulverized coal is combusted at high-pressure with negligible recycle. A unique burner and boiler have been designed via computational fluid dynamics (CFD) to effectively and safely burn coal under SPOC conditions. CFD is used to model the process and to determine the effects of operating conditions on the radiative and convective heat transfer in the boiler. It is shown through the simulations that a manageable wall heat flux can be achieved even with very high local gas temperatures. The system is also designed to minimize particle deposition to avoid slagging, fouling, and corrosion, and simulations of ash deposition indicate negligible deposition on the furnace wall. Radiation behavior is also studied to demonstrate radiative trapping effects. It is demonstrated, through both analytical and numerical studies, that the system pressurize is a critical tool to obtain an optically thick medium capable of trapping heat inside the furnace. It is further shown that for a sufficiently large optical thickness radiative trapping can occur, and this, combined with the diffusive-convective profiles of the temperature and absorption coefficient, allow us manage the wall heat flux. An average-temperature method is developed to approximate the heat flux and to study the dynamic relations of temperature and the absorption coefficient. The effects of ash particle size on radiative trapping are systematically studied. It is concluded that the wall heat flux is controlled by particle size as well as particle number concentration, in other words, by particle porosity and fragmentation. Ultimately, burners and boilers are designed to minimize the boiler heat transfer surface area, ash deposition, and fire-side corrosion for the SPOC system. Part II. Understanding the structure of diffusion flames is often complicated by the dependence of flame structure on the boundary conditions, such as composition, temperature, and flow field (e.g., strain rate in a counterflow flame.) The utility of interpreting flame results in the carbon-to-oxygen atom ratio (C/O ratio) space, as opposed to physical space or mixture fraction space, is evaluated. Flame and soot zone structures of counterflow diffusion flames are studied for C2H4 and C3H8 and interpreted in C/O ratio space as a function of the stoichiometric mixture fraction (Zst). The Burke-Schumann results expressed in C/O ratio space demonstrate how a clear and direct understanding of how structure is affected by Zst can be realized. In C/O ratio space, unlike physical or mixture fraction space, the flame location is independent of the stoichiometric mixture fraction. Numerical results with detailed chemical kinetics also indicate that C/O ratio space is a fundamental variable in the sense that, for a given fuel, the location of the flame zones and critical reactions is invariant with Zst and strain rate. Two zones are clearly observed, the radical pool zone and the soot precursor zone which is located on the fuel side of the flame. The onset threshold of soot precursors (C6H5 and C6H6) on the high temperature side of the soot precursor zone is characterized by the depletion of radicals. The role of the hydrogen radical in flame structure and soot inception is demonstrated by studying its production and consumption channels in C/O ratio space, as are the roles of C2H2 in soot precursor depletion and boundary coincidence. The kinetic ratio is used to study the characteristics of key chemical reactions and to identify regions of equilibrium for these reactions. Finally, a modified C/O ratio ((C/O)*) is given to interpret the physical meaning of C/O ratio. The numerical results in this work indicate and explain the advantages of applying C/O ratio space in the analysis of flame structure and soot precursor chemistry.

This book was released on 2016-08-09 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.

Available in PDF, EPUB and Kindle. Book excerpt: Concern over the effects of airborne pollution, green house gases, and the impact of global warming has become a worldwide issue that transcends international boundaries, politics, and social responsibility. The 2nd Edition of Coal Energy Systems: Clean Coal Technology describes a new generation of energy processes that sharply reduce air emissions and other pollutants from coal-burning power plants. Coal is the dirtiest of all fossil fuels. When burned, it produces emissions that contribute to global warming, create acid rain, and pollute water. With all of the interest and research surrounding nuclear energy, hydropower, and biofuels, many think that coal is finally on its way out. However, coal generates half of the electricity in the United States and throughout the world today. It will likely continue to do so as long as it's cheap and plentiful [Source: Energy Information Administration]. Coal provides stability in price and availability, will continue to be a major source of electricity generation, will be the major source of hydrogen for the coming hydrogen economy, and has the potential to become an important source of liquid fuels. Conservation and renewable/sustainable energy are important in the overall energy picture, but will play a lesser role in helping us satisfy our energy demands today. Dramatically updated to meet the needs of an ever changing energy market, Coal Energy Systems, 2nd Edition is a single source covering policy and the engineering involved in implementing that policy. The book addresses many coal-related subjects of interest ranging from the chemistry of coal and the future engineering anatomy of a coal fired plant to the cutting edge clean coal technologies being researched and utilized today. A 50% update over the first edition, this new book contains new chapters on processes such as CO2 capture and sequestration, Integrated Gasification Combined Cycle (IGCC) systems, Pulverized-Coal Power Plants and Carbon Emission Trading.
