This book was released on 2017 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this project was scaling up and evaluating a novel Amine Functionalized Aerogel (AFA) sorbent in a bench scale fluidized bed reactor. The project team (Aspen Aerogels, University of Akron, ADA-ES, and Longtail Consulting) has carried out numerous tests and optimization studies to demonstrate the CO2 capture performance of the AFA sorbent in all its forms: powder, pellet, and bead. The CO2 capture target performance of the AFA sorbent (all forms) were set at> 12 wt.% and> 6 wt.% for total and working CO2 capacity, respectively (@ 40 °C adsorption / 100 - 120 °C desorption). The optimized AFA powders outperformed the performance targets by more than 30%, for the total CO2 capacity (14 - 20 wt.%), and an average of 10 % more for working CO2 capacity (6.6 - 7.0 wt.%, and could be as high as 9.6 wt. % when desorbed at 120 °C). The University of Akron developed binder formulations, pellet production methods, and post treatment technology for increased resistance to attrition and flue gas contaminants. In pellet form the AFA total CO2 capacity was ~ 12 wt.% (over 85% capacity retention of that of the powder), and there was less than 13% degradation in CO2 capture capacity after 20 cycles in the presence of 40 ppm SO2. ADA-ES assessed the performance of the AFA powder, pellet, and bead by analyzing sorption isotherms, water uptake analysis, cycling stability, jet cup attrition and crush tests. At bench scale, the hydrodynamic and heat transfer properties of the AFA sorbent pellet in fluidized bed conditions were evaluated at Particulate Solid Research, Inc. (PSRI). After the process design requirements were completed, by Longtail Consulting LLC, a techno-economic analysis was achieved using guidance from The National Energy Technology Laboratory (NETL) report. This report provides the necessary framework to estimate costs for a temperature swing post combustion CO2 capture process using a bituminous coal fired, super-critical steam cycle power plant producing 550 MWe net generation with 90% CO2 capture using a methylethylamine (MEA) solvent. Using the NETL report as guidance, the designed CO2 capture system was analyzed on a cost basis to determine relative cost estimates between the benchmark MEA system and the AFA sorbent system.

Download or read book Evaluation of Novel Metal organic Framework Materials for Adsorptive Post combustion CO2 Capture written by Johan D. Baboolal and published by . This book was released on 2015 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mitigation of CO2 emissions from large anthropogenic sources such as coal-fired power plants by CO2 capture is a challenging engineering problem. Due to the large scale of energy generation, post-combustion CO2 capture processes must be very low-cost for practical implementation. The current industry standard technology for CO2 capture, absorption, separates CO2 from post-combustion flue gas by scrubbing with a liquid amine solvent, and is very energy intensive. Pressure swing adsorption (PSA) uses a porous, solid adsorbent material to separate CO2 and N2, and is a potentially lower energy alternative to absorption, due to the regeneration simply requiring a reduction in pressure. The benchmark or standard adsorbent which has been considered and evaluated in literature for post-combustion CO2 capture is zeolite 13X. Recently, several novel metal-organic framework (MOF) materials have been reported in literature to have potential as alternatives to zeolite 13X, however evaluation of these MOFs in a PSA process has not been done. This research will be focused on the evaluation of two types of MOFs in a PSA process using simulated flue gas as a feed, and comparing their performance to zeolite 13X. The first type of MOF evaluated, called SiF6 or SIFSIX, was reported in literature to not be significantly affected by the presence of water. Zeolite 13X, however, has a significantly reduced CO2 capacity when water vapor is present in flue gas. Two types of SIFSIX materials were investigated, SIFSIX-2-Cu-i and SIFSIX-3-Zn. The experimental adsorption isotherms of these materials were fitted to a Langmuir model, and this was incorporated into a full PSA model. Optimization of the SIFSIX adsorbents and zeolite 13X under feed of 15% CO2 and 85% N2 showed that both SIFSIX adsorbents have similar purity and recovery performance when compared to 13X. An energy and productivity analysis was also performed, and SIFSIX-2-Cu-i had a similar energy requirement compared to Zeolite 13X, with a minimum energy of 155 kWh/t CO2 captured. The minimum energy for SIFSIX-3-Zn was 140 kWh/t CO2, however the very sharp isotherm of SIFSIX-3-Zn results in a productivity of 0.18 mol/m3 adsorbent/s, which is significantly lower than that for 13X, at 0.42 mol/m3 adsorbent/s and SIFSIX-2-Cu-i at 0.75 mol/m3 adsorbent/s. These results indicate that in a dry case, Zeolite 13X is a better adsorbent than SIFSIX-3-Zn, and SIFSIX-2-Cu-i has performance which is only marginably better. The second type of MOF evaluated for post-combustion capture is a diamine-appended MOF, mmen-Fe2. This type of adsorbent was reported in the literature to have an S shaped or type V adsorption isotherm. A quadratic-langmuir isotherm model was employed to fit the adsorption isotherm of mmen-Fe2 at a temperature of 30C. The performance of mmen-Fe2 and Zeolite 13X was then compared by an optimization study, which revealed that the minimum energy for the mmen-Fe2 adsorbent was 110kWh/t CO2, compared to that of 13X which was 135 kWh/t CO2. The reduction in energy was due to a higher blowdown pressure being possible in the mmen-Fe2 adsorbent due to its capacity for N2 being significantly less than Zeolite 13X. The S-shaped CO2 isotherm was also beneficial, as the increased working capacity of CO2 resulted in a productivity for mmen-Fe2 which was 1 mol/m3 adsorbent/s, almost twice that of Zeolite 13X, at 0.55 mol/m3 adsorbent/s. Therefore, the mmen-Fe2 adsorbent is a good candidate for CO2 capture by VSA considering its better performance than zeolite 13X in terms of both energy and productivity.

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 Pilot Scale Evaluation of an Advanced Carbon Sorbent Based Process for Post Combustion Carbon Capture written by and published by . This book was released on 2016 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this project is to achieve the DOE's goal to develop advanced CO2 capture and separation technologies that can realize at least 90% CO2 removal from flue gas steams produced at a pulverized coal (PC) power plant at a cost of less than $40/tonne of CO2 captured. The principal objective is to test a CO2 capture process that will reduce the parasitic plant load by using a CO2 capture sorbent that will require a reduced amount of steam. The process is based on advanced carbon sorbents having a low heat of adsorption, high CO2 adsorption capacity, and excellent selectivity. While the intent of this project was to produce design and performance data by testing the sorbent using a slipstream of coal-derived flue gas at the National Carbon Capture Center (NCCC) under realistic conditions and continuous long-term operation, the project was terminated following completion of the detailing pilot plant design/engineering work on June 30, 2016.

Download or read book Capture of CO2 from Pre combustion Gas by Adsorption Processes at High Temperatures written by Gongkui Xiao and published by . This book was released on 2011 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The capture and storage of CO2 from coal have received considerable attention due to a growing demand for green use of carbon-based resources concerning its global warming effect. There are usually two ways of capturing CO2 from coal-related gases according to locations of capture blocks, post-combustion and pre-combustion. The conventional approach for pre-combustion CO2 capture is liquid absorption. However, one potential limitation of this process is that the liquid scrubbing must occur at relatively low temperatures (near ambient). By contrast, adsorbent based processes offer the potential of higher temperature capture eliminating the intermediate cooling and reheating steps. Therefore there is a motivation to develop high temperature adsorption processes.This project investigates the capture of CO2 by solid adsorbents from pre-combustion coal gasification syngas in an Integrated Gasification Combined Cycle (IGCC) process at high temperatures. The project covers materials development and process testing on both a real gasifier and a synthetic pre-combustion gas stream provided in our laboratory.Adsorbents screening was performed with real coal gasification syngas from a pilot coal gasifier. Breakthrough and regeneration experiments with hydrotalcite MG 70, calcium chabazite, and zeolite 13X were performed on the custom-made gas separation apparatus at 120 °C and 200 °C. Zeolite 13X was found to be a potentially good adsorbent for CO2 separation provided T200 °C. Thereafter, different VPSA processes using zeolite 13X were designed to pursue a CO2 purity of 95% with synthetic syngas. The designed processes were then validated with real coal gasification gas. However, simulation results for the separation from full scale syngas showed that using zeolite 13X to reach a purity of > 95% would be very costly.High temperature adsorbents composed of MgO and K2CO3 were prepared and characterized by various means. These prepared adsorbents possessed high CO2 sorption capacity and cycling stability both under dry and wet conditions. An adsorption model was proposed for the prepared adsorbent and provided an adequate description of the adsorption and desorption experiments performed on a thermogravimetric analyser. The derived isotherm from the proposed model was also able to represent the experimental isothermal adsorption data well. Although the CO2 adsorption kinetics of these adsorbents were higher than other reported high temperature adsorbents, they were still much slower than widely used physical adsorbents, which makes it currently not very efficient for pressure swing adsorption processes. In future work, efforts will be focused on increasing the adsorption and desorption kinetics by, for example making these adsorbents to nanoscale, possibly supported on porous substrates.
