CROSSCUTTING COMPUTATION The challenges posed by the need for innovative solutions to carbon capture cannot be met by experimentation alone. Cutting across all possible solutions―membranes, liquid solutions, solid sorbents, or other as yet unknown approaches―appropriate, innovative computation and modeling approaches are needed for significant progress in understanding routes to more effectively reducing CO2 emissions. The capability to predict thermodynamic and chemical equilibria, reaction dynamics, and the transport of gaseous target molecules in liquid substrates or solid materials is essential for the design and optimization of carbon capture technologies. Even for established approaches, such as large-scale separation processes, such data are not always available. For example, although it is common to find measurements of pure component adsorption isotherms in the literature, isotherms for mixtures of gases are less often available for optimization and design. This lack of information often promotes the adoption of untested approximations of, say, the ideal behavior of the mixture in the absence of reliable data or predictions of mixture behavior. As methodologies for carbon capture advance, turning to new and different materials and conditions and different characteristic length and time scales, the relevant thermodynamic, transport, and kinetic data are even less likely to be available. This situation creates a strong driving force to turn to computational calculations to predict properties that enable the design and optimization of new carbon capture processes. Computational approaches include first principles calculations (quantum chemistry, ab initio molecular dynamics), molecular simulations (such as molecular dynamics and Monte Carlo– based techniques), larger-scale computational routes (including coarse-grained simulations; solution of partial differential equations; and stochastic simulation-based approaches such as Brownian, dissipative particle, and Stokesian dynamics). A number of carbon capture mechanisms—for example, liquid absorption based on adsorbents that chemically react with CO2 during CO2 uptake (see the Liquid Absorbents panel report)—involve chemical reactions, many of which are ill-characterized or presently unknown. First principles methods can be used to determine reaction pathways and compute reaction rates. Molecular-scale simulations rely on the availability of accurate models for molecular interactions, known as force fields. While many force fields are available for small molecules such as CO2, O2, N2, and water, cross interactions with the new materials that could be considered for carbon capture (e.g., carbon nanotubes, porous materials, polymers) may not be available. Parameterizing these interactions invariably requires first principles calculations (e.g., quantum chemistry calculations) and knowledge of the interaction between the guest molecule and host molecules. For ordered crystalline materials, the host structure is well understood; however, for many complex materials, including amorphous materials, these structures are poorly characterized and new means to create representative structures of amorphous materials are needed. Once the required parameters are available, molecular simulations can readily be carried out to determine thermodynamic equilibria and transport of guest molecules at process conditions. Coarse-grained and other mesoscopic simulation techniques also have a significant role to play. Molecular simulations can take advantage of explicit representation of each atom in the system by simpler objects (e.g., beads or other geometric shapes) that retain the essential geometry and interactions of the particles. Such representations allow 100PDF Image | 2020 Carbon Capture
