The study of CO2 absorption intensification using porous media material in aqueous AMP solution

Petroleum, 2018
In this work, the performance of CO2 absorption into aqueous 2-amino-2-methyl-propanol (AMP) solution was investigated by measuring the amount of CO2 in the liquid phase during CO2 absorption process to identify initial CO2 absorption rate.

Utilization of a CO₂ Storage Material: Shape-Controlled Preparation of CaCO₃ Microspheres

Crystals, 2019
Homogeneous CaCO3 microspheres were controllably synthesized via a simple hydrothermal method without using extraneous additives by Ca(OH)2 saturated solution reacted with CO2 storage material (CO2SM), which was obtained by absorbing CO2 gas in a system ...

Numerical simulation of displacement characteristics of CO2 injected in pore-scale porous media

Journal of Rock Mechanics and Geotechnical Engineering, 2016
Pore structure of porous media, including pore size and topology, is rather complex. In immiscible two-phase displacement process, the capillary force affected by pore size dominates the two-phase flow in the porous media, affecting displacement results.
