  • Measurement and thermodynamic modeling of the phase equilibrium of aqueous 2-amino-2-methyl-1-propanol solutions
    Fluid Phase Equilibria, 2006
    Co-Authors: Georgia D. Pappa, Christos Anastasi, Epaminondas Voutsas
    Abstract:

    Abstract The accurate design of Acid Gas Treatment processes requires the knowledge of vapor–liquid equilibrium of Acid Gas aqueous alkanolamine systems, and, consequently, that of the binary systems involved. This study presents: (a) vapor pressure measurements of pure 2-amino-2-methyl-1-propanol (AMP), and (b) isobaric vapor–liquid equilibrium (VLE) measurements at 66.7, 80.0 and 101.3 kPa of aqueous AMP solutions. The data measured in this work along with some excess enthalpy data, which were taken from the literature, were used for the thermodynamic modeling of the water/AMP binary system.

  • model development and process simulation of postcombustion carbon capture technology with aqueous amp pz solvent
    International Journal of Greenhouse Gas Control, 2016
    Co-Authors: Mijndert Van Der Spek, Richard Arendsen, Andrea Ramírez, André Faaij
    Abstract:

    Abstract This study presents the development, application, and uncertainty analysis of a process simulation model for postcombustion CO 2 capture with an AMP/PZ solvent blend based on state of the art knowledge on AMP/PZ solvent technology. The development includes the improvement of the physical property models of a software package designed for simulation of Acid Gas Treatment and CO 2 capture technologies. The improvement particularly consisted of regression of AMP–PZ binary interaction parameters. The model was applied to a case study of postcombustion CO 2 capture from an Advanced Super Critical Pulverized Coal power plant. Uncertainly analysis was undertaken by validating the physical property models against laboratory measurements reported in literature; by comparing model results with pilot study results, and by evaluating the strength of the model with a novel method called pedigree analysis. The results show that AMP/PZ postcombustion technology performs better than MEA technology on most performance indicators, e.g., the Specific Reboiler Duty is reduced from 3.6 GJ/t CO 2  for MEA, to 2.9 GJ/t CO 2 for AMP/PZ, and the specific cooling water requirement is reduced from 4.1 to 3.4 GJ/t CO 2 . Only amine slip to the atmosphere increases with AMP/PZ technology: from 0.18 g/t CO 2 to 15.3 g/t CO 2 , although this value is still within emission limits from existing regulatory frameworks. The coal power plant net efficiency with AMP/PZ capture amounts to a value of 37.2% LHV , compared to 46.1% LHV for the case without CCS and 36.2% LHV in case of CCS with MEA. The uncertainty analysis shows that the model is well capable of predicting experimental and pilot result. The remaining uncertainty is mostly in the reaction kinetics and in the flowsheet design. Validation could be further improved, by more elaborate comparison to independent measures of physical properties, and by comparison of the model outputs to results from large demonstration or commercial size capture plants.

  • Single-particle characterization of municipal solid waste (MSW) ash particles using low-Z particle electron probe X-ray microanalysis
    Atmospheric Environment, 2006
    Co-Authors: Heejin Hwang, Chul-un Ro
    Abstract:

    Abstract Environmentally benign Treatment of municipal solid waste (MSW) ashes has been a worldwide issue since more countries are implementing incineration to reduce waste volume. A single-particle analytical technique, named low-Z particle electron probe X-ray microanalysis (low-Z particle EPMA) was applied to characterize MSW fly- and bottom-ash particle samples collected from two municipal incinerators in Korea. According to their chemical composition, many distinctive particle types were identified. For fly ash sample collected in one incinerator (sample S1), where lime slurry injection is used for Acid–Gas Treatment, CaCO3-containing particles (28.4%) are the most abundantly encountered, followed by carbonaceous (23.6%), SiO2-containing (13.8%), NaCl-containing (13.1%), and iron-containing (10.5%) particles. For fly ash sample collected at the other incinerator (sample S2), NaCl-containing particles (40.4%) are the most abundantly encountered, followed by iron-containing (29.1%), carbonaceous (11.8%), CaCO3-containing (2.2%), and SiO2-containing (7.0%) particles. For bottom ash sample collected at one incinerator (sample S3), iron-containing particles (46.6%) are the most abundantly encountered, followed by CaCO3-containing (17.3%), carbonaceous (16.6%), and Si and/or Al oxide-containing (15.8%) particles. For bottom ash sample collected in the other incinerator (sample S4), iron-containing particles (63.4%) are also the most abundantly encountered, followed by carbonaceous (14.0%), CaCO3-containing (10.0%), and Si and/or Al oxide-containing (6.1%) particles. Chemical compositions of the two bottom ash samples are not much different compared to those of the two fly ash samples. It was demonstrated that the single-particle characterization using this low-Z particle EPMA technique provided detailed information on various types of chemical species in the MSW ash samples. In addition, the technique has advantage over conventional analytical techniques in the point that both crystalline- and glass-like ash particles can be analyzed at the same time.
