A comprehensive database of experimental and computed data for the viscosity of carbon dioxide (CO2) was compiled and a new reference correlation was developed. Literature results based on an ab initio potential energy surface were the foundation of the correlation of the viscosity in the limit of zero density in the temperature range from 100 K to 2000 K. Guided symbolic regression was employed to obtain a new functional form that extrapolates correctly to T → 0 K and to 10 000 K. Coordinated measurements at low density made it possible to implement the temperature dependence of the Rainwater-Friend theory in the linear-in-density viscosity term. The residual viscosity could be formulated with a scaling term ργ/T the significance of which was confirmed by symbolic regression. The final viscosity correlation covers temperatures from 100 K to 2000 K for gaseous CO2, and from 220 K to 700 K with pressures along the melting line up to 8000 MPa for compressed and supercritical liquid states. The data representation is more accurate than with the previous correlations, and the covered pressure and temperature range is significantly extended. The critical enhancement of the viscosity of CO2 is included in the new correlation.

“…The industrial deployment of postcombustion CO 2 ‐capture technologies will have a larger economic impact on the reduction of capture costs than the other options. However, in the best scenario, for a new power plant equipped with the current postcombustion capture technologies, the cost of capture is estimated to be approximately 56 USD t −1 , which incurs an energy penalty of 62 % to the power plant . Carbon capture has already been commercialized in chemical production and the natural gas industry.…”

Carbon Capture and Utilization Update

et al. 2017

In recent years, carbon capture and utilization (CCU) has been proposed as a potential technological solution to the problems of greenhouse‐gas emissions and the ever‐growing energy demand. To combat climate change and ocean acidification as a result of anthropogenic CO2 emissions, efforts have already been put forth to capture and sequester CO2 from large point sources, especially power plants; however, the utilization of CO2 as a feedstock to make valuable chemicals, materials, and transportation fuels is potentially more desirable and provides a better and long‐term solution than sequestration. The products of CO2 utilization can supplement or replace chemical feedstocks in the fine chemicals, pharmaceutical, and polymer industries. In this review, we first provide an overview of the current status of CO2‐capture technologies and their associated challenges and opportunities with respect to efficiency and economy followed by an overview of various carbon‐utilization approaches. The current status of combined CO2 capture and utilization, as a novel efficient and cost‐effective approach, is also briefly discussed. We summarize the main challenges associated with the design, development, and large‐scale deployment of CO2 capture and utilization processes to provide a perspective and roadmap for the development of new technologies and opportunities to accelerate their scale‐up in the near future.

“…Hydrogen is produced at large scale (≈50 million tons year −1 ) from fossil fuels with CO 2 as a byproduct. H 2 /CO 2 separation is essential to produce pure H 2 and for capturing CO 2 to mitigate its emission to the atmosphere . However, the state‐of‐the‐art CO 2 capture technology (i.e., the Selexol process) is expensive and may increase the cost of electricity production by 30%.…”

“…Membranes have favorable H 2 /CO 2 diffusivity selectivity because of the smaller kinetic diameter of H 2 (2.89 Å) versus CO 2 (3.3 Å), but have unfavorable H 2 /CO 2 solubility selectivity because CO 2 is much more condensable than H 2 1c. The conventional approach to improving H 2 /CO 2 selectivity is to increase size‐sieving ability, as exemplified by polybenzimidazole (PBI) or cross‐linked PBIs 2b,3.…”

Mixed matrix membranes (MMMs) comprising size-sieving fillers dispersed in polymers exhibit diffusivity selectivity and may surpass the upper bound for gas separation, but their performance is limited by defects at the polymer/ filler interface. Herein, a fundamentally different approach employing a highly sorptive filler that is inherently less sensitive to interfacial defects is reported. Palladium nanoparticles with extremely high H 2 sorption are dispersed in polybenzimidazole at loadings near the percolation threshold, which increases both H 2 permeability and H 2 /CO 2 selectivity. Performance of these MMMs surpasses the state-of-the-art upper bound for H 2 /CO 2 separation with polymer-based membranes. The success of these sorption-enhanced MMMs for H 2 /CO 2 separation may launch a new research paradigm that taps the enormous knowledge of affinities between gases and nanomaterials to design MMMs for a wide variety of gas separations.
