“…Putting this into context, the solubility limit of water in pure CO2 over the range of conditions expected for CCS (5-85°C and 7.3-30.0 MPa), is around 1700 ppm or higher before free water precipitation occurs. [16,27] Figure 3, which is extracted from a publication by de Visser et al [16] outlines in more detail how the solubility of water varies as a function of temperature and pressure over the range of -10 to 25°C and 1.0 to 20.0 MPa. The figure shows that increasing temperature serves to increase the solubility limit of water in CO2.…”

Carbon Capture and Storage (CCS) has been highlighted as a potential method to enable the continued use of fossil-fuelled power stations through the abatement of carbon dioxide (CO2). A complete CCS cycle requires safe, reliable and cost effective solutions for the transmission of CO2 from the capturing facility to the location of permanent storage. In subsequent sections, early laboratory and field corrosion experience relating to natural dense phase CO2 transport for the purposes of enhanced oil recovery (EOR) are summarised along with more recent research efforts which focus on identifying the role of anthropogenic impurities in the degradation processes. For each system impurity, the reaction rates, mechanisms and corrosion product composition/morphology expected at the steel surfaces are discussed, as well as each component's ability to influence the critical water content required to initiate corrosion. Potential bulk phase reactions between multiple impurities are also evaluated in an attempt to help understand how the impurity content may evolve along a long distance pipeline.The likelihood of stress-corrosion cracking and hydrogen-induced cracking is discussed and the various corrosion mitigation techniques which exist to control degradation to acceptable 2 levels are reviewed. Based on the current research performed in the context of impure dense phase CO2 corrosion, issues associated with performing laboratory experiments to replicate field conditions and the challenges such limitations present in terms of defining the safe operating window for CO2 transport are considered.

“…Pipeline transport of CO 2 allows a large volume of material to be moved directly from the source to the storage 1 . However, CO 2 output from large facilities is likely to contain a varying number and percentage of impurities, depending upon the capture process. These impurities can significantly shift the thermophysical properties of the mixture, relative to that of pure CO 2 .…”

Molecular simulation of the thermophysical properties and phase behaviour of impure CO₂ relevant to CCS

Impurities from the CCS chain can greatly influence the physical properties of CO 2 . This has important design, safety and cost implications for the compression, transport and storage of CO 2 . There is an urgent need to understand and predict the properties of impure CO 2 to assist with CCS implementation. However, CCS presents demanding modelling requirements. A suitable model must both accurately and robustly predict CO 2 phase behaviour over a wide range of temperature and pressure, and maintain that predictive power for CO 2 mixtures with numerous, mutually interacting chemical species. A promising technique to address this task is molecular simulation. It offers a molecular approach, with foundations in firmly established physical principles, along with the potential to predict the wide range of physical properties required for CCS. The quality of predictions from molecular simulation depends on accurate force-fields to describe the interactions between CO 2 and other molecules. Unfortunately, there is currently no universally applicable method to obtain force-fields suitable for molecular simulation.In this paper we present two methods of obtaining force-fields: the first being semi-empirical and the second using ab initio quantum-chemical calculations. In the first approach we optimise the impurity force-field against measurements of the phase and pressure-volume behaviour of CO 2 binary mixtures with N 2 , O 2 , Ar and H 2 . A gradient-free optimiser allows us to use the simulation itself as the underlying model. This leads to accurate and robust predictions under conditions relevant to CCS. In the second approach we use quantum-chemical calculations to produce ab initio evaluations of the interactions between CO 2 and relevant impurities, taking N 2 as an exemplar. We use a modest number of these calculations to train a machine-learning algorithm, known as a Gaussian process, to describe these data. The resulting model is then able to accurately predict a much broader set of ab initio force-field calculations at comparatively low numerical cost. Although our method is not yet ready to be implemented in a molecular simulation, † Electronic Supplementary Information (ESI) available: [details of any supplementary information available should be included here].

“…The pressure, the mass flow rate and the composition entering the PSA unit are dictated by the process upstream. The CO2-rich gas stream leaving PSA needs to be compressed to 110 bar for transportation, with a CO2 volumetric concentration above 95% [17]. The second product stream leaving PSA is rich in H2.…”

The main goal of this paper is to provide a comprehensive overview on the performance of an Integrated Gasification Combined Cycle (IGCC) implementing CO2 capture through a Pressure Swing Adsorption (PSA) process. The methodology for integrating a PSA process into the IGCC plant is first defined and then a full-plant model is developed. A reference case is outlined both for the PSA-based plant and for an absorption-based plant. Physical absorption is considered the benchmark technology for the application investigated. The full-plant model allowed an assessment of the potentials of PSA in this framework. The plant performance obtained was evaluated mainly in terms of energy penalty and CO2 separation efficiency. Several process configurations and operating conditions were tested. The results of these simulations demonstrated the influence of the PSA process on the overall performance and the possibility to shape it according to specific requirements. A sensitivity analysis on the adsorbent material was also carried out, aiming to establish the possible performance enhancements connected to advancements in the material. Improving the properties of the adsorbent demonstrated to have a strong impact not only on the CO2 separation process but also on the performance of the entire plant. However, nor modifications in the process or in the material were able to fully close the gap with absorption. In this sense a synergetic approach for addressing further performance enhancements is outlined, based on the close collaboration between process engineering and material science.
