Lu L, Wang S, Muller EA, Cao W, Zhu Y, Lu X, Jackson Get al., 2013, Adsorption and separation of CO2/CH4 mixtures using nanoporous adsorbents by molecular simulation, Fluid Phase Equilibria, Vol: 362, Pages: 227-234, ISSN: 0378-3812

A grand canonical Monte Carlo-simulation (GCMC) study is presented focussing on the adsorption of CO2/CH4 mixtures in different nanopore models, including pristine mesoporous carbons, carbon foams, carbon nanotubes (CNTs), and nanopore models modified with hydrophilic carboxylic groups. We also report and discuss the selectivity of the different adsorbent surfaces under a wide range of temperature and pressure. Our results show that foam structures have the highest adsorption capacity of all the pristine structures studied because of its special architecture. The selectivity markedly enhanced after modification, especially at low pressures, and modified CNTs are found to have the highest selectivity among all the models tested. The effect of temperature and pressure is evaluated and the change in the selectivity trends of modified nanopore models are in contrast to that of the pristine models. The results suggest that the separation performance in carbon nanopores is greatly affected by the nature of the architecture and the heterogeneity of the materials. These findings could be beneficial in conventional pressure swing adsorption processes and the nanoporous structures could be used as parts of mixed polymer membranes. The results of this work present some guidelines for the designing nanoporous structures in order to achieve optimal separation of CO2/CH4 mixtures.

A model of a desorber for the recovery of aqueous monoethanolamine (MEA) solvent following the separation of carbon dioxide (CO2) from flue gas from a fossil fuel power plant is presented. This model is derived from a previously developed absorber model, by using the same rate-based stage and physical property models. The novelty of this modeling framework lies in the integration into a rate-based process model of the state-of-the-art SAFT-VR thermodynamic model, in which the physical and chemical interactions are treated simultaneously, assuming that the chemical reactions are at equilibrium. Such an approach reduces the amount of experimental data needed to model the interactions of the solvent with CO2. The implicit treatment of the chemical reactions in this formalism obviates the need to incorporate an enhancement factor or to use experimental data for the rate of reaction. The gPROMS software is employed to implement the desorber model and pilot plant data are used for the validation, without adjusting any model parameters. Very good predictions are obtained over a wide range of operating conditions.

SAFT-γ Mie is a new equation of state recently developed by the Molecular Systems Engineering group at Imperial College London. It is an advanced group-contribution form of the SAFT equation of state making use of the Mie potential for a more accurate and flexible description of the dispersive/repulsive interactions between segments. One of its key characteristics is the accurate description of vapour/liquid phase equilibria, including the region of the critical point, as well as the second-derivative thermodynamic properties such as the thermal expansivity, isothermal compressibility, heat capacity, Joule-Thomson coefficient, and speed of sound. In 2009, Process Systems Enterprise (PSE) acquired the exclusive intellectual property rights associated with SAFT-γ Mie and related work, for the purpose of incorporating these developments within its gSAFT advanced thermodynamics technology for process modelling. In late 2010, TOTAL, PSE and Imperial College embarked on a joint project aimed at exploring in detail the applicability, benefits and limitations of this technology on a wide range of mixtures of interest to the oil & gas industry. The current phase of the project is primarily focused on mixtures of hydrocarbons (alkanes and aromatics), carbon dioxide, water and methanol. The main output is a single, consistent set of group parameters capable of accurately describing the behaviour of these generic mixtures within the SAFT-γ Mie framework. Starting with a brief overview of the SAFT-γ Mie equation of state, this paper primarily focuses on the systematic methodology employed in developing the corresponding like and unlike group parameters. This comprises a sequence of steps including the choice of representative components and mixtures, the definition of an appropriate set of groups required to describe them, the collection of the necessary experimental data, a streamlined set of software tools and workflows employed for the accurate, ef
