This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The capture/separation step for carbon dioxide (CO2) from large-point sources is a critical one with respect to the technical feasibility and cost of the overall carbon sequestration scenario. For large-point sources, such as those found in power generation, the carbon dioxide capture techniques being investigated by the in-house research area of the National Energy Technology Laboratory possess the potential for improved efficiency and reduced costs as compared to more conventional technologies. The investigated techniques can have wide applications, but the research has focused on capture/separation of carbon dioxide from flue gas (post-combustion from fossil fuel-fired combustors) and from fuel gas (precombustion, such as integrated gasification combined cycle or IGCC). With respect to fuel gas applications, novel concepts are being developed in wet scrubbing with physical absorption; chemical absorption with solid sorbents; and separation by membranes. In one concept, a wet scrubbing technique is being investigated that uses a physical solvent process to remove CO2 from fuel gas of an IGCC system at elevated temperature and pressure. The need to define an ideal solvent has led to the study of the solubility and mass transfer properties of various solvents. Pertaining to another separation technology, fabrication techniques and mechanistic studies for membranes separating CO2 from the fuel gas produced by coal gasification are also being performed. Membranes that consist of CO2-philic ionic liquids encapsulated into a polymeric substrate have been investigated for permeability and selectivity. Finally, dry, regenerable processes based on sorbents are additional techniques for CO2 capture from fuel gas. An overview of these novel techniques is presented along with a research progress status of technologies related to membranes and physical solvents.

Download or read book Climate Intervention written by National Research Council and published by National Academies Press. This book was released on 2015-06-17 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: The signals are everywhere that our planet is experiencing significant climate change. It is clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases from our atmosphere if we want to avoid greatly increased risk of damage from climate change. Aggressively pursuing a program of emissions abatement or mitigation will show results over a timescale of many decades. How do we actively remove carbon dioxide from the atmosphere to make a bigger difference more quickly? As one of a two-book report, this volume of Climate Intervention discusses CDR, the carbon dioxide removal of greenhouse gas emissions from the atmosphere and sequestration of it in perpetuity. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration introduces possible CDR approaches and then discusses them in depth. Land management practices, such as low-till agriculture, reforestation and afforestation, ocean iron fertilization, and land-and-ocean-based accelerated weathering, could amplify the rates of processes that are already occurring as part of the natural carbon cycle. Other CDR approaches, such as bioenergy with carbon capture and sequestration, direct air capture and sequestration, and traditional carbon capture and sequestration, seek to capture CO2 from the atmosphere and dispose of it by pumping it underground at high pressure. This book looks at the pros and cons of these options and estimates possible rates of removal and total amounts that might be removed via these methods. With whatever portfolio of technologies the transition is achieved, eliminating the carbon dioxide emissions from the global energy and transportation systems will pose an enormous technical, economic, and social challenge that will likely take decades of concerted effort to achieve. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration will help to better understand the potential cost and performance of CDR strategies to inform debate and decision making as we work to stabilize and reduce atmospheric concentrations of carbon dioxide.
Download or read book Separation of Carbon Dioxide from Fuel Gas pre combustion Capture Via Hydrate Crystallization written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional coal-fired power plants that rely on the combustion of the coal are the largest anthropogenic point sources of atmospheric carbon dioxide (CO2). An alternative approach of producing electricity with CO2 capture is pre-combustion decarbonisation whereby the coal is used to produce an intermediate hydrogen-rich gas (CO2/H2 mixture). This route is known as integrated gasification combined cycle (IGCC). The CO2/H2 mixture is called fuel gas and is separated into a CO2-rich and a H2-rich stream. The H2 may be burnt to produce electricity or used in fuel cells. The assumption is that the CO2 can possibly be stored safely in a suitable geological formation. It is noted that other fossil fuels may be used in a similar manner as coal. This thesis examines the prospect of employing a novel method for the separation of carbon dioxide (CO2) from CO2/H2 mixture (fuel gas mixture) via clathrate hydrate crystal formation. Experiments and theory are employed at the engineering (macroscopic) and molecular level to achieve the objectives. The focus is on the study of the thermodynamic and kinetic properties of CO2/H2 and CO2/H2/C3H hydrates. The basis for separation of the CO2 is the fact that when a CO2/H2 or CO2/H2/C3H mixture is allowed to form hydrate, CO2 preferentially gets incorporated into the hydrate phase. The addition of 2.5 mol % C3H8 in the fuel gas mixture was found to reduce the hydrate formation pressure and thus improve the process economics. Based on the data obtained a conceptual separation process was developed. It involves two hydrate stages coupled with a membrane-based gas separation stage. The two hydrate stages operate at ~3.5 MPa and 273.7 K. The power penalty for a 500 MW power plant is estimated to be about 2.5% of the power output. Crystal structures and cage occupancies for the CO2/H2 and the CO2/H2/C3H8 hydrate were determined using several spectroscopic techniques. This enabled an understanding of the separation efficiency values obtaine.

Download or read book Negative Emissions Technologies and Reliable Sequestration written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-04-08 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.
Download or read book Recent Advances in Carbon Capture and Storage written by Yongseung Yun and published by BoD – Books on Demand. This book was released on 2017-03-08 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon capture and storage (CCS) has been considered as a practical way in sequestering the huge anthropogenic CO2 amount with a reasonable cost until a more pragmatic solution appears. The CCS can work as a bridge before fulfilling the no-CO2 era of the future by applying to large-scale CO2 emitting facilities. But CCS appears to lose some passion by the lack of progress in technical developments and in commercial success stories other than EOR. This is the time to go back to basics, starting from finding a solution in small steps. The CCS technology desperately needs far newer ideas and breakthroughs that can overcome earlier attempts through improving, modifying, and switching the known principles. This book tries to give some insight into developing an urgently needed technical breakthrough through the recent advances in CCS research, in addition to the available small steps like soil carbon sequestration. This book provides the fundamental and practical information for researchers and graduate students who want to review the current technical status and to bring in new ideas to the conventional CCS technologies.
