Measurement and modelling of mass diffusion coefficients for application in carbon dioxide storage and enhanced oil recoveryTrusler, J.P. Martin, Cadogan, Shane P., Maitland, Geoffrey C., Secuianu, Catinca 30 January 2020 (has links)
In this work, measurements were carried out by the Taylor dispersion method [1, 2] to determine the
mutual diffusion coefficient for CO2 in water or hydrocarbon at effectively infinite dilution.
Measurements were carried out for CO2 in water, hexane, heptane, octane, decane, dodecane,
hexadecane, cyclohexane, squalane and toluene at temperatures between 298 K and 423 K with
pressures up to 69 MPa. Measurements of CO2 diffusivity in different brines were also carried out by
13C pulsed-field gradient NMR.
