Chemical Engineering Thermodynamics: A Key Factor in CO2 Removal Methodologies

The quest to reduce greenhouse gas emissions has led to the development of innovative technologies aimed at removing carbon dioxide from gaseous mixtures. One crucial aspect of this process is understanding chemical engineering thermodynamics, which plays a vital role in predicting selectivity and adsorption coefficients. In this article, we will explore the significance of molecular dynamics simulations in assessing separation and adsorption properties of graphtriyne membranes on CO2-rich gas streams.

The accuracy of force fields used in molecular dynamics simulations is critical in providing reliable predictions of selectivity and adsorption coefficients. Post-combustion gaseous products are often modeled using these mixtures, as they closely resemble the composition of industrial flue gases. Graphtriyne membranes have gained attention for their potential application in CO2 removal methodologies due to their high selectivity and permeability.

A recent study used molecular dynamics simulations to assess the separation and adsorption properties of multi-layered graphtriyne membranes on gaseous mixtures of CO2, N2, and H2O. The results demonstrated the membrane's ability to remove carbon dioxide from the mixture, making it a promising technology for reducing greenhouse gas emissions.

From a computational fluid dynamics (CFD) perspective, the coupling between real-fluid thermodynamics and governing equations under transcritical conditions poses significant numerical challenges. To address these issues, researchers have developed fully conservative (FC) and quasi-conservative (QC) numerical schemes for simulating advection problems involving transcritical contact discontinuities.

The versatility of this thermodynamic model is noteworthy, as it can represent both supercritical states and subcritical stable two-phase states at equilibrium via a homogeneous mixture approach. This allows researchers to simulate a wide range of conditions, including those relevant to aerospace propulsion applications.

In conclusion, chemical engineering thermodynamics plays a critical role in developing innovative technologies for CO2 removal methodologies. The molecular dynamics simulations used in this study demonstrate the potential of graphtriyne membranes for separating carbon dioxide from gaseous mixtures. As researchers continue to advance our understanding of thermodynamic processes, we can expect significant progress in reducing greenhouse gas emissions and mitigating climate change.
