Influence of supercritical CO2 on the physical property of tight sandstone

Petroleum
In low-pressure gas reservoirs, water-based fracture fluid is difficult to flowback, which is unfavorable for several tight sandstone gas reservoirs in the Sichuan Basin with low pressure and high permeability geological characteristics.

Dynamic modelling of a fractionation process for a liquid mixture using supercritical carbon dioxide [PDF]

, 2001
This work presents a simple dynamic modelling of a process of separation of a quaternary mixture using supercritical CO2. Thermodynamic description is accomplished using efficient available models (SRK equation of state with MHV2 mixing rules).

Electrodeposition from supercritical fluids

, 2014
Recent studies have shown that it is possible to electrodeposit a range of materials, such as Cu, Ag and Ge, from various supercritical fluids, including hydrofluorocarbons and mixtures of CO2 with suitable co-solvents. In this perspective we discuss the

Carrying Gold in Supercritical CO2 [PDF]

Gold Bulletin, 1999
A series of fluorinated calixarene derivatives, with lower rim sulfur-donor atoms, were synthesized and studied for the sequestration of gold using supercritical fluid extraction. Following temperature and pressure optimization and using extracts collected in methyliso-butyl ketone, analysis by flame atomic absorption spectrometry reveals that Au(III ...

Fluid phase equilibria of the reacting mixture in the dimethyl carbonate synthesis from supercritical CO2 [PDF]

, 2003
In order to investigate the dimethyl carbonate synthesis from methanol and supercritical CO2, the thermodynamic behaviour of the reacting mixture, i.e. the quaternary methanol/CO2/DMC/water mixture, has to be known.

Mixed CO2/N2 Foam for EOR as a Novel Solution for Supercritical CO2 Foam Challenges in Sandstone Reservoirs

ACS Omega, 2020
Among the various enhanced oil recovery (EOR) processes, CO2 injection has been widely utilized for oil displacement in EOR. Unfortunately, gas injection suffers from gravity override and high mobility, which reduces the sweep efficiency and oil recovery.

In Situ Raman Analysis of CO\u2082-Assisted Drying of Fruit-Slices [PDF]

, 2017
This work explores the feasibility of applying in situ Raman spectroscopy for the online monitoring of the supercritical carbon dioxide (SC-CO\u2082) drying of fruits. Specifically, we investigate two types of fruits: mango and persimmon.

Different Effect Mechanisms of Supercritical CO2 on the Shale Microscopic Structure

ACS Omega, 2020
To better understand how supercritical carbon dioxide (CO2) enhances shale gas production, it is necessary to study the interaction of supercritical CO2 with shale and its impact on shale microstructure.
