چکیده
Understanding the solubility of CO2 is critical for implementing CO2-enhanced oil recovery (CO2-EOR). In this work, in n-decane a temperature range between 303.15 K and 353.15 pressures up to 15 MPa was measured using fused silica capillary cell with situ Raman spectroscopy. A semi-empirical prediction model obtained according experimental results. order improve n-decane, co-solvent n-hexane (3% wt) mixture also comparatively investigated. The results indicated that 1.6355~64.0084 mol/kg. data from were good agreement data, mean relative deviation 3.65%, indicating could be used predict under different conditions. + system ranged 1.0127 mol/kg 65.7286 It found that, low-pressure conditions, addition did not enhance CO2, while it had certain enhancement effect on dissolution high-pressure As increased K, efficiency 1.34~2.05% 8.17~9.82%, average 1.74% 9.00%. This study provides more CO2-EOR.

The calculation of viscosity of liquid n-decane and n-hexadecane by the Green-Kubo method
This short commentary presents the result of long molecular dynamics simulation calculations of the shear viscosity of liquid n-decane and n-hexadecane using the Green± Kubo integration method. The relaxation time of the stress± stress correlation function is compared with those of rotation and di usion. The rotational and di usional relaxation times, which are easy to calculate, provide usef...
متن کاملElectrokinetic detection for X-ray spectra of weakly interacting liquids: n-decane and n-nonane.
The introduction of liquid microjets into soft X-ray absorption spectroscopy enabled the windowless study of liquids by this powerful atom-selective high vacuum methodology. However, weakly interacting liquids produce large vapor backgrounds that strongly perturb the liquid signal. Consequently, solvents (e.g., hydrocarbons, ethers, ketones, etc.) and solutions of central importance in chemistr...

The solubility of xenon in liquid n-pentane and n-hexane has been studied experimentally, theoretically, and by computer simulation. Measurements of the solubility are reported for xenon + n-pentane as a function of temperature from 254 to 305 K. The uncertainty in the experimental data is less than 0.15%. The thermodynamic functions of solvation such as the standard Gibbs energy, enthalpy, and...
