This book was released on 2012 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide and mercury from anthropogenic emissions pose a significant threat to our environment and human health. Removal from their major source -- coal-fired power plants -- is one of the most effective approaches to control their emissions. Thermodynamics and kinetics are critical to the studies of the removal technologies as they provide fundamental knowledge of the capture process. In this work, the thermodynamics and kinetics of CO2 and Hg capture through absorption using aqueous amines solutions and adsorption using supported ionic liquid sorbents were investigated. A vapor-liquid equilibrium (VLE) data reduction method that simplifies experimental measurements while maintaining accuracy was applied for the first time to the thermodynamic study of CO2 absorption in aqueous amine systems. The method eliminates the measurements of speciation in liquid phase and vapor phase by applying a layer of mass balance iteration in the correlation. Incorporating the electrolyte non-random two liquid (eNRTL) model and the Soave-Redlich-Kwong (SRK) model, the data reduction method was used to correlate VLE and heat of absorption data collected in a modified batch calorimeter for ethanolamine (MEA) - H2O - CO2 system and piperazine (PZ) - H2O - CO2 systems. The optimized model with the best-fit eNRTL model parameters was used to predict vapor pressures under the conditions reported in the literature; the predicted values were consistent with the independent literature results, indicating successful application of the Barker data reduction method and the mathematical model in the thermodynamic study of CO2-aqueous amine systems. With the current technologies, capture of CO2 and Hg from coal combustion flue gas requires additional air pollution control devices that can only do a single task . To reduce the cost, a new approach to capture both CO2 and Hg from coal combustion flue gas in an integrated adsorbent system was discovered. In this approach, a task-specific amino acid ionic liquid is supported on silica gel particles with high surface area and pore volume. The CO2 capacity for was found to be 0.4 mol of CO2/ mol of ionic liquid. The ionic liquid loading was optimal for CO2 capture at 40 wt%. Mass transfer in fixed-bed trials was slow at high ionic liquid loadings due to the decreasing in contact surface area. Hg capture performance was assessed for the same material under a nitrogen environment. These sorbent systems had a total Hg uptake of more than 14 mg/g. Slipstream testing of the sorbents, along with other novel Hg sorbents developed previously, using coal combustion flue gas showed promising and competitive results in Hg removal rate and Hg capacity. When both CO2 and Hg are present in the gas phase, it is expected that Hg accumulates and fixes in the sorbent via strong chemical bonding over an extended time, while CO2 can reversibly be adsorbed and desorbed on the sorbent. This hypothesis was validated by the experimental evidence that the present of CO2 has limited effect on the capture of elemental Hg vapor and the theoretical evidence that oxidized Hg has a stronger bonding with the ionic liquid than CO2.

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.

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.

Book excerpt: Absorption-Based Post-Combustion Capture of Carbon Dioxide provides a comprehensive and authoritative review of the use of absorbents for post-combustion capture of carbon dioxide. As fossil fuel-based power generation technologies are likely to remain key in the future, at least in the short- and medium-term, carbon capture and storage will be a critical greenhouse gas reduction technique. Post-combustion capture involves the removal of carbon dioxide from flue gases after fuel combustion, meaning that carbon dioxide can then be compressed and cooled to form a safely transportable liquid that can be stored underground. Provides researchers in academia and industry with an authoritative overview of the amine-based methods for carbon dioxide capture from flue gases and related processes Editors and contributors are well known experts in the field Presents the first book on this specific topic

Available in PDF, EPUB and Kindle. Book excerpt: UOP LLC, a Honeywell Company, in collaboration with Professor Douglas LeVan at Vanderbilt University (VU), Professor Adam Matzger at the University of Michigan (UM), Professor Randall Snurr at Northwestern University (NU), and Professor Stefano Brandani at the University of Edinburgh (UE), supported by Honeywell's Specialty Materials business unit and the Electric Power Research Institute (EPRI), have completed a three-year project to develop novel microporous metal organic frameworks (MOFs) and an associated vacuum-pressure swing adsorption (vPSA) process for the removal of CO2 from coal-fired power plant flue gas. The project leveraged the team's complementary capabilities: UOP's experience in materials development and manufacturing, adsorption process design and process commercialization; LeVan and Brandani's expertise in high-quality adsorption measurements; Matzger's experience in syntheis of MOFs and the organic components associated with MOFs; Snurr's expertise in molecular and other modeling; Honeywell's expertise in the manufacture of organic chemicals; and, EPRI's knowledge of power-generation technology and markets. The project was successful in that a selective CO2 adsorbent with good thermal stability and reasonable contaminant tolerance was discovered, and a low cost process for flue gas CO2 capture process ready to be evaluated further at the pilot scale was proposed. The team made significant progress toward the current DOE post-combustion research targets, as defined in a recent FOA issued by NETL: 90% CO2 removal with no more than a 35% increase in COE. The team discovered that favorable CO2 adsorption at more realistic flue gas conditions is dominated by one particular MOF structure type, M/DOBDC, where M designates Zn, Co, Ni, or Mg and DOBDC refers to the form of the organic linker in the resultant MOF structure, dioxybenzenedicarboxylate. The structure of the M/DOBDC MOFs consists of infinite-rod secondary building units bound by DOBDC resulting in 1D hexagonal pores about 11 angstroms in diameter. Surface areas range from 800 to 1500 sq m/g for the different MOFs. Mg/DOBDC outperformed all MOF and zeolite materials evaluated to date, with about 25 wt% CO2 captured by this MOF at flue gas conditions ((almost equal to)0.13 atm CO2 pressure, 311K). In simulated flue gas without oxygen, the zero-length (ZLC) system was very useful in quickly simulating the effect of long term exposure to impurities on the MOFs. Detailed adsorption studies on MOF pellets have shown that water does not inhibit CO2 adsorption for MOFs as much as it does for typical zeolites. Moreover, some MOFs retain a substantial CO2 capacity even with a modest water loading at room temperature. Molecular modeling was a key activity in three areas of our earlier DOE/NETL-sponsored MOF-based research on CC. First, the team was able to effectively simulate CO2 and other gas adsorption isotherms for more than 20 MOFs, and the knowledge obtained was used to help predict new MOF structures that should be effective for CO2 adsorption at low pressure. The team also showed that molecular modeling could be utilized to predict the hydrothermal stability of a given MOF. Finally, the team showed that low moisture level exposure actually enhanced the CO2 adsorption performance of a particular MOF, HKUST-1.

This book was released on 2019-02-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.
