Large Pilot Testing of Linde-BASF Advanced Post-Combustion CO2 Capture Technology at a Coal-Fired Power Plant [CWLP] [FE0031581]
No full textResearchers at the University of Illinois, in partnership with the Linde Group, BASF Corporation, Affiliated Engineers, Inc., and Affiliated Construction Services, Inc., are designing an amine-based carbon dioxide (CO2) capture pilot-scale (10 megawatt-electric [MWe]) system at an existing coal-fired power plant. The system is based on the Linde-BASF advanced CO2 capture process incorporating BASF’s novel solvent with an advanced stripper inter-stage heater design to optimize heat recovery. In a previous U.S. Department of Energy (DOE)-funded project, the Linde-BASF CO2 capture technology showed the potential to be cost-effective and energy-efficient using actual flue gas during pilot-scale (1.5 MWe) testing at the National Carbon Capture Center. The aqueous amine-based solvent was optimized to exhibit long-term stability and a 20 percent reduction in regeneration energy requirements when compared to commercially available solvents; additional improvements in process design further reduce the cost of CO2 capture.
Projects to design, construct, and operate large-scale pilots of transformational coal technologies are being conducted in three phases, with a down-select between phases. In Phase I of this project, the team completed preliminary design and engineering analyses for a 10 MWe capture facility installed at three potential host sites and selected the City, Water, Light and Power’s (CWLP) Dallman Power Plant as the host site based on the studies. The project team also completed an Environmental Information Volume (EIV) for the selected site, updated preliminary cost and schedule estimates, secured cost-share commitments for Phase II, and developed a plan for securing cost-share commitments for Phase III. The project was selected for Phase II (Design), in which the team will complete a front-end engineering design (FEED) study, including a detailed cost and schedule estimate for Phase III for the installation of the 10 MWe pilot at CWLP, complete the National Environmental Policy Act (NEPA) process and any required permitting processes at CWLP, secure Phase III (construction/operation) cost share funding, and complete an updated techno-economic analysis of the technology based on the most recent system design and cost information.
The Phase III objectives are to complete detailed engineering, procurement of equipment and modules, and build and operate a 10 MWe large pilot of the Linde/BASF post-combustion carbon capture technology at the CWLP Dallman Power Plant in Springfield, Illinois. The Phase III scope of work includes: (1) obtaining construction and operating permits for all regulated activities occurring during Phase III; (2) finalizing functional specifications and completing detailed engineering; (3) procuring equipment and materials for inside and outside the boundary limits (ISBL and OSBL); (4) constructing and installing the large pilot; (5) commissioning of the large pilot plant followed by parametric and steady-state operating test campaigns; (6) analyzing test campaign results; and (7) updating the techno-economic analysis (TEA) based on the design and cost information developed during the Phase III test campaign.
The approach used for design, construction, and commissioning is an important feature of the technology and will help enable the commercialization process. The regional economic benefit and the ability to repurpose some existing workforce at CWLP will also demonstrate how carbon capture can aid regional economies when it is deployed. If the technology performs as planned, there is a desire to have the capture plant remain in place and be utilized for future testing of capture and utilization technologies.Open Restriction set for Item 118175 on 2021-08-25T18:02:54Z with date null by [email protected] by Laura Barnes ([email protected]) on 2021-08-25T18:21:42Z

Molecular structure of highly excited resonant states in Mg-24 and the corresponding Be-8+O-16 and C-12+C-12 decays
No full textExotic Be-8 and C-12 decays from high-lying resonances in Mg-24 are analyzed in terms of a cluster model. The calculated quantities agree well with the corresponding experimental data. It is found that the calculated decay widths are very sensitive to the angular momentum carried by the outgoing cluster. It is shown that this property makes cluster decay a powerful tool to determine the spin as well as the molecular structures of the resonances.Physics, NuclearSCI(E)7ARTICLE5null8

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

B -> eta K-c(eta ' K-c) decays in QCD factorization
No full textWe study the exclusive decays of the B meson into pseudoscalar charmonium states eta(c) and eta(c)' within the QCD factorization approach and find that the non-factorizable corrections to naive factorization are infrared safe at leading-twist order. The spectator interactions arising from the kaon twist-3 effects are formally power suppressed but chirally and logarithmically enhanced. An important improvement by including the O(alpha(s)) corrections is the cancellation of the renormalization scale mu dependence of the decay amplitude. However, the calculated decay rates are too small to accommodate the experimental data. On the other hand, we compare the theoretical calculations for B meson decays to J/psi, psi', eta(c) and eta'(c), and find that the predicted relative decay rates of these four states are approximately compatible with the experimental data.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000223097800007&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, Particles & FieldsSCI(E)17ARTICLE3365-3703

Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

Microscopic mechanism of charged-particle radioactivity and generalization of the Geiger-Nuttall law
No full textA linear relation for charged-particle emissions is presented starting from the microscopic mechanism of the radioactive decay. It relates the logarithms of the decay half-lives with two variables, called. chi' and. rho', which depend upon the Q values of the outgoing clusters as well as the masses and charges of the nuclei involved in the decay. This relation explains well all known cluster decays. It is found to be a generalization of the Geiger-Nuttall law in a radioactivity, and therefore we call it the universal decay law. Predictions of the most likely emissions of various clusters are presented by applying the law over the whole nuclear chart. It is seen that the decays of heavier clusters with nonequal proton and neutron numbers are mostly located in the trans-lead region. The emissions of clusters with equal protons and neutrons, like (12)C and (16)O, are possible in some neutron-deficient nuclei with Z >= 54.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000271352900039&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, NuclearSCI(E)51ARTICLE4null8
