Information Derivation from Vapor-Liquid Equilibria Data: A Simple Shortcut to Evaluate the Energy Performance in an Amine-Based Postcombustion CO Capture.

Evaluation of amine absorbents is crucial for the development of a technically and economically feasible CO capture process. However, the capture performance estimation usually requires a load of experiments, which is time-consuming and labor-intensive. The present study proposed a simple but effective shortcut that employs the fewest experimental data, i.

Innovative use of membrane contactor as condenser for heat recovery in carbon capture.

The gas-liquid membrane contactor generally used as a nonselective gas absorption enhancement device is innovatively proposed as a condenser for heat recovery in liquid-absorbent-based carbon capture. The membrane condenser is used as a heat exchanger to recover the latent heat of the exiting vapor from the desorber, and it can help achieve significant energy savings when proper membranes with high heat-transfer coefficients are used. Theoretical thermodynamic analysis of mass and heat transfer in the membrane condensation system shows that heat recovery increases dramatically as inlet gas temperature rises and outlet gas temperature falls.

One-pot preparation and CO2 adsorption modeling of porous carbon, metal oxide, and hybrid beads.

Hierarchically porous carbon (C), metal oxide (ZrTi), or carbon-metal oxide (CZrTi) hybrid beads are synthesized in one pot through the in situ self-assembly of Pluronic F127, titanium and zirconium propoxides, and polyacrylonitrile (PAN). Upon contact with water, a precipitation of PAN from the liquid phase occurs concurrently with polymerization and phase separation of the inorganic precursors. The C, ZrTi, and CZrTi materials have similar morphologies but different surface chemistries.
