Plume Migration of Different Carbon Dioxide Phases During Geological Storage in Deep Saline Aquifers

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2015
This study estimates the plume migration of mobile supercritical phase (flowing), aqueous phase (dissolved), and ionic phase CO2 (bicarbonate), and evaluates the spatial distribution of immobile supercritical phase (residual) and mineral phase CO2 ...

An Experiment on Flashing-Spray Jet Characteristics of Supercritical CO2 from Various Orifice Geometries

open access: yesFrontiers in Energy Research, 2021
Supercritical CO2 pipelines usually are used to link the CO2 capture system to the geological storage. There are severe hazards once the asphyxiating gas leaks from the long-distance pipeline.

Characterizing the Dissolution Rate of CO2-Brine in Porous Media under Gaseous and Supercritical Conditions

open access: yesApplied Sciences, 2017
The CO2-brine dissolution homogenizes the distribution of residual CO2 and reduces the leakage risk in the saline aquifer. As a key parameter to immobilize the free CO2, the dissolution rate of CO2-brine could be accelerated through mechanisms like ...

Fracturing in coals with different fluids: an experimental comparison between water, liquid CO2, and supercritical CO2

open access: yesScientific Reports, 2020
The present work conducted laboratory experiments of fracturing in fat coals, anthracites, and mudstones. Three different fluids were selected as the fracturing fluids, including water, liquid CO2 (L-CO2), and supercritical CO2 (Sc-CO2).
