Book Description
This book focuses on the recent trends in carbon management and up-to-date information on different carbon management strategies that lead to manage increasing concentration of atmospheric carbon dioxide. The growing evidence of climate change resulting from the continued increase of atmospheric carbon dioxide concentration has made it a high profile political–social and trade issue. The mean global average earth temperature rose by 0.6± 2°C during the second half of the century with the rate of 0.17°C/decade. As per GISS data in the year of 2017, it rose 0.9°C (1.62 °F) above the 1951-1980 mean global temperature. Recently World Meteorological Organization analyzes the past record temperature and found the past 10 years were the warmest years about 1.1°C above preindustrial level. Over the past decade, carbon management by various techniques has to come to fore as a way to manage carbon dioxide emissions contributing to climate change. The proposed book addresses the need for an understanding of sustainable carbon dioxide management technologies mainly focused on (a) minimizing carbon dioxide emission from sources; (b) maximizing environmentally sound recuse, reduce and recycling; (c)emerging technology toward carbon dioxide mitigation and d) converting carbon dioxide into valuable products form sustainable use. Other books related to carbon management attempt to cover the carbon capture and sequestration, carbon mineralization, utilization and storage but the topic of CO2 management strategies is not discussed in detail for sustainable development. Furthermore, this book also covers all physical, chemical and biological process for long-term capture, removal and sequestration of carbon dioxide from the atmosphere for sustainable management which is not described in other carbon management books. In order to meet CO2 emissions reduction target, a range of technological approaches, including development of clean fuels and clean coal technologies, adopting cleaner and more energy efficiency and conservation, developing renewable energy and implementing CCS technologies, will also be considered for sustainable future.

Book Description
This book focuses on an important technology for mineralizing and utilizing CO2 instead of releasing it into the atmosphere. CO2 mineralization and utilization demonstrated in the waste-to-resource supply chain can “reduce carbon dependency, promote resource and energy efficiency, and lessen environmental quality degradation,” thereby reducing environmental risks and increasing economic benefits towards Sustainable Development Goals (SDG). In this book, comprehensive information on CO2 mineralization and utilization via accelerated carbonation technology from theoretical and practical considerations was presented in 20 Chapters. It first introduces the concept of the carbon cycle from the thermodynamic point of view and then discusses principles and applications regarding environmental impact assessment of carbon capture, storage and utilization technologies. After that, it describes the theoretical and practical considerations for “Accelerated Carbonation (Mineralization)” including analytical methods, and systematically presents the carbonation mechanism and modeling (process chemistry, reaction kinetics and mass transfer) and system analysis (design and analysis of experiments, life cycle assessment and cost benefit analysis). It then provides physico-chemical properties of different types of feedstock for CO2 mineralization and then explores the valorization of carbonated products as green materials. Lastly, an integral approach for waste treatment and resource recovery is introduced, and the carbonation system is critically assessed and optimized based on engineering, environmental, and economic (3E) analysis. The book is a valuable resource for readers who take scientific and practical interests in the current and future Accelerated Carbonation Technology for CO2 Mineralization and Utilization.

Book Description
SequesTech(TM) ((TM) -Proprietary process, patent held by University of Wyoming US patent approved: 20090280046) Increasing anthropogenic CO2 levels in the atmosphere are raising concerns over climate change and global warming. Flue gas emissions from industrial processes, particularly from coal-fired power plants, are a major source for the release of anthropogenic CO2 into the atmosphere. Concurrently these processes also generate significant quantities of solid residues (ash particles) as a by-product. Multiple CO2 capture and storage (CCS) processes are required to address the anthropogenic CO2 problem. However, a method which can directly capture and mineralize CO2 at a point source, under actual field conditions, has advantages and could help offset the cost associated with the conventional CCS technologies. Objectives of this research were to develop a pilot scale fluidized-bed process and test the effects of moisture content of flue gas on accelerated mineral carbonation process of fly ash particles. A pilot scale fluidized-bed process was designed and tested at one of the largest (Jim Bridger) coal-fired power plants (2120 MW) in the USA by reacting flue gas with fly ash particles. The pilot scale process consisted of a moisture reducing drum (MRD) (0.9 m [phi] × 1.8 m), a heater/humidifier (0.9 m [phi] × 1.8 m), and a fluidized bed reactor (FBR) (0.9-1.2 m [phi] × 3.7 m). Flue gas was withdrawn from the stack and was fed to the MRD at about 0.094 m 3 /s. The MRD and the heater/humidifier pretreat flue gas before it enters the FBR. The MRD captures droplets of water entrained in the flue gas to protect the blower placed between the MRD and the heater/humidifier. The heater/humidifier enables control of flue gas moisture and temperature. Approximately 100-640 kg of fresh fly ash was collected from the electrostatic precipitator through ash hopper and placed in the FBR. Fly ash particles were fluidized by the flow of flue gas through a distributor plate in the FBR. Pilot scale studies were all conducted at 200 SCFM and at a controlled pressure (115.1 kPa) under various flue gas moisture contents (2-16 mol%). The flue gas moisture was controlled by controlling the temperature (25-60° C) of the humidifier water. Experiments were conducted up to 120 minutes by reacting the flue gas with fly ash in the FBR. The flue gas CO2, SO2 and NOx concentrations were monitored before and during the experiments by an industrial grade gas analyzer. Fly ash samples were collected from a sample port over 0-120 minutes. Control and treated fly ash samples were analyzed for total inorganic carbon (C), sulfur (S), and mercury (Hg). From C, S, and Hg concentrations, percent calcium carbonate (CaCO3), percent sulfate (SO42−), and percent HgCO3 were calculated, respectively. Results suggested that among different temperature conditions, 60° C (~16 mol% moisture) showed highest mineralization of flue gas CO2 and SO2. The average percent CaCO3 and average percent SO42− in the 60° C fly ash samples increased from 1.25 to 3.67% and from 0.33 to 2.36%, respectively. The percent HgCO3 in the fly ash samples increased from 0.02 to 0.36% after reacting with flue gas during an experiment on July 28, 2010 when the flue gas temperature ranged between 25 and 58° C (corresponding to ~4-14 mol% moisture). These pilot scale studies suggest that an appreciable amount of flue gas CO2 and significant amounts of SO2 and Hg can be directly captured (without separation) and mineralized by the fly ash particles. The proposed accelerated mineral carbonation process is economical with minimum carbon footprint and can be retrofitted to existing and/or new coal fired power plants as a post-combustion unit. Used in conjunction with capture and geologic sequestration, the accelerated mineral carbonation process has the potential to reduce overall cost associated with CO2 separation/compression/transportation/pore space/brine water treatment. It could also help protect sensitive amines and carbon filters used in flue gas CO2 capture and separation processes and extend their life.
