  • 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.

  • Ultralow Parasitic Energy for Postcombustion CO2 Capture Realized in a Nickel Isonicotinate Metal–Organic Framework with Excellent Moisture Stability
    Journal of the American Chemical Society, 2017
    Co-Authors: Shyamapada Nandi, Sean P. Collins, Tom K. Woo, Debanjan Chakraborty, Debasis Banerjee, Praveen K. Thallapally, Ramanathan Vaidhyanathan
    Abstract:

    Metal–organic frameworks (MOFs) have attracted significant attention as solid sorbents in gas separation processes for low-energy Postcombustion CO2 capture. The parasitic energy (PE) has been put forward as a holistic parameter that measures how energy efficient (and therefore cost-effective) the CO2 capture process will be using the material. In this work, we present a nickel isonicotinate based ultramicroporous MOF, 1 [Ni-(4PyC)2·DMF], that has the lowest PE for Postcombustion CO2 capture reported to date. We calculate a PE of 655 kJ/kg CO2, which is lower than that of the best performing material previously reported, Mg-MOF-74. Further, 1 exhibits exceptional hydrolytic stability with the CO2 adsorption isotherm being unchanged following 7 days of steam-treatment (>85% RH) or 6 months of exposure to the atmosphere. The diffusion coefficient of CO2 in 1 is also 2 orders of magnitude higher than in zeolites currently used in industrial scrubbers. Breakthrough experiments show that 1 only loses 7% of its...

  • Experimental and Simulation Study of Adsorption in Postcombustion Conditions Using a Microporous Biochar. 1. CO2and N2Adsorption
    Industrial & Engineering Chemistry Research, 2016
    Co-Authors: Marta G. Plaza, Fernando Rubiera, Inés Durán, Nausika Querejeta, Covadonga Pevida
    Abstract:

    The influence of N2 on CO2 adsorption was evaluated using a microporous biochar with a narrow pore size distribution. The adsorption isotherms of pure CO2 and N2 were measured at 0, 30, 50, and 70 °C up to 120 kPa and fitted to the Toth adsorption model. Dynamic breakthrough experiments were carried out in a fixed-bed adsorption unit using binary mixtures with compositions representative of different Postcombustion streams (8–30% CO2) from ambient temperature to 70 °C. Dynamic adsorption experiments were simulated to validate the mathematical model of the adsorption process, as a necessary step for its later use for process design. The Ideal Adsorption Solution (IAS) theory, based on the pure component adsorption models, was used to account for competitive adsorption with satisfactory results. The information gathered in the present work will be used to extend the validity of the model to the adsorption of Postcombustion streams containing H2O in part 2.Work was carried out with financial support from the HiPerCap\ud Project of the European Union 7th Framework Programme\ud FP7 (2007-2013; Grant Agreement number: 60855).

  • Green coffee based CO2 adsorbent with high performance in Postcombustion conditions
    Fuel, 2015
    Co-Authors: Marta G. Plaza, A.s. González, Covadonga Pevida, Fernando Rubiera
    Abstract:

    Abstract An environmentally friendly and low cost adsorbent, PPC (patent application filed Gonzalez (2013)), produced from an abundant residue from the food industry, coffee grounds, is presented and evaluated as CO 2 adsorbent in Postcombustion conditions. PPC is a high bulk density pelletized carbon with adequate properties for its use in fixed-bed adsorption applications. The equilibrium capacity for CO 2 at low partial pressures, relevant for the Postcombustion case, in the 25–50 °C temperature range is superior to that of reference carbons, both in mass and volume basis. PPC presents equilibrium selectivity for CO 2 over N 2 , with CO 2 /N 2 equilibrium separation factor values of 15–25 at 50 °C and 130 kPa for CO 2 concentrations between 9% and 31%. Moreover, it presents fast adsorption kinetics, which makes it a good candidate for rapid swing adsorption cycles. Different VSA cycle configurations were carried out at 50 °C in the fixed-bed adsorption unit to evaluate the performance of the adsorbent in cyclic operation. The adsorbent did not show any sign of deactivation over extended operation.

  • Valorisation of spent coffee grounds as CO2 adsorbents for Postcombustion capture applications
    Applied Energy, 2012
    Co-Authors: Marta G. Plaza, A.s. González, Covadonga Pevida, José J. Pis, Fernando Rubiera
    Abstract:

    In this work spent coffee grounds from single-use capsules were used as the starting material for producing low-cost activated carbons. The activation conditions were selected and optimised to produce microporous carbons with high CO2 adsorption capacity and selectivity, thus with potential to be used as adsorbents in Postcombustion CO2 capture applications. Two activation methods are compared: physical activation with CO2 and chemical activation with KOH. The first method is considered less contaminant; however, leads to carbons with lower textural development and thus lower CO2 adsorption capacity than those obtained by activation with KOH. On the other hand, multicomponent adsorption cyclic experiments pointed out that the CO2/N2 selectivity of physically activated carbons is higher than that of chemically activated carbons.

  • Development of low-cost biomass-based adsorbents for Postcombustion CO2 capture
    Fuel, 2009
    Co-Authors: Marta G. Plaza, Covadonga Pevida, Fernando Rubiera, Borja Arias, J. Fermoso, M.d. Casal, C. F. Martin, José J. Pis
    Abstract:

    In this work a series of carbon adsorbents were prepared from a low-cost biomass residue, olive stones. Two different approaches were studied: activation with CO2 and heat treatment with gaseous ammonia. The results showed that both methods are suitable for the production of adsorbents with a high CO2 adsorption capacity, and their potential application in VSA or TSA systems for Postcombustion CO2 capture. It was found that the presence of nitrogen functionalities enhances CO2 adsorption capacity, especially at low partial pressures.
