Diffusion coefficients and oil swelling factors of carbon dioxide, methane, ethane, propane, and their mixtures in heavy oil

Analysis of Heavy Oil Emulsion-Carbon Dioxide System on Oil-Swelling Factor and Interfacial Tension by Using Pendant Drop Method for Enhanced Oil Recovery and Carbon Dioxide Storage

“…linked with computer. Reference [8] illustrates the detail of volume calculation from the dynamic pendant oil drop as shown in (2):…”

“…Swelling of crude oil by any type of gas injection for viscosity reduction has been studied for decades [8]. It is beneficial for oil recovery in that it helps to reduce oil viscosity.…”

“…It is beneficial for oil recovery in that it helps to reduce oil viscosity. The pendant drop volume analysis method has been used successfully to measure and calculate the diffusion coefficients and oil swelling factors of heavy oil-solvent systems [8]. The advantages of this method over the other existing ones are that a single experimental test can be achieved with less time consumption.…”

Experimental and Theoretical Determination of Equilibrium Interfacial Tension for the Solvent(s)–CO2–Heavy Oil Systems

“…PR EOS Model. Because of its wide application in the petroleum and chemical industries, the PR EOS 19 is chosen as the EOS for describing the phase behavior of 0.786 C 39 1.583 C 10 0.844 C 40 1.600 C 11 1.037 C 41 0.750 C 12 1.267 C 42 0.830 C 13 1.817 C 43 1.380 C 14 1.950 C 44 0.929 C 15 2.300 C 45 0.929 C 16 2.143 C 46 0.700 C 17 2.286 C 47 0.833 C 18 2.238 C 48 0.792 C 19 2.048 C 49 0.792 C 20 1.857 C 50 0.733 C 21 2.071 C 51 0.750 C 22 1.329 C 52 0.717 C 23 1.743 C 53 0.717 C 24 1.571 C 54 0.683 C 25 1.714 C 55 0.650 C 26 1.600 C 56 0.650 C 27 1.583 C 57 0.667 C 28 1.650 C 58 0.667 C 29 1.452 C 59 0.667 C 30 1.281 C 60+ 36.164 …”

Gas-Expanded Lubricants for Increased Energy Efficiency and Control in Rotating Machinery

“…The diffusion of carbon dioxide into various fluids [48][49][50][51][52][53][54][55][56][57][58][59][60] and the diffusion of refrigerants into lubricant oils [40,[61][62][63][64] are described in the literature. Despite this effort, the diffusion of carbon dioxide into synthetic oils had yet to be reported.…”
