  1. Diffusion Coefficients in Crude Oil: DCCO STS-91 - G765 Diffusion Coefficients in Crude Oil

  2. DCCO experiment belongs to a wide research program aiming to investigate mass transport processes in multicomponents mixtures representatives of crude oil: DSC: Diffusion and Soret Coefficients Measurement for Oil Recovery. Diffusion Coefficients in Crude Oil

  3. DSC : ESA Map Project MAP Program: With the forthcoming International Space Station, there is strong motivation to expand on microgravity related activities notably by involving European industry and by encouraging the move from fundamental research towards applied projects. ESA has therefore initiated a Microgravity Applications Promotion Program that includes Physical Sciences and Biotechnology. The DSC Project is part of that program. Diffusion Coefficients in Crude Oil

  4. DSC MAP Programme • Measurements of isothermal diffusion and thermal diffusion coefficients (or Soret effect) in various kind of mixtures, • Implementation of the results in thermodynamics numerical models of oil reservoirs, • Creation of a database of standard data’s that will be used to validate ground-based measurements methods, • Measurement of the influence of g-jitters on diffusion and thermodiffusion coefficients Diffusion Coefficients in Crude Oil

  5. International collaboration between academic institutions and industry • Belgium • France • Denmark • Canada Diffusion Coefficients in Crude Oil

  6. Project Coordinator: Microgravity Research Centre, Brussels University • Main research areas : Physics of fluids • Transport and interface modeling • Evaporation and mass transfer at interfaces • Hydrodynamic instabilities • Instabilities in multi-component systems • Diffusion and Soret effect • Liquid bridges • Experiment design • Fluid Physics Facility (Fluidpac), on the Foton Retrievable Capsule • 3D Flow Visualisation for JET on Maser 8 Sounding Rocket • Fluid Science Lab (FSL) Facility for the ISS • Interfacial Turbulence in Evaporating Liquids (ITEL experiment) on MASER 9. • Parabolic flights hardware Diffusion Coefficients in Crude Oil

  7. DSC: “Diffusion and Soret Coefficients Measurements for Improvement of Oil Recovery.” < DCCO SCCO> DSC-F < DCCO Diffusion Coefficients in Crude Oil

  8. DSC : Theoretical developments • DCCO, SCCO and DSC modeling (Ryerson Polytechnic University) • Molecular dynamics (MASTER Laboratory) • Modeling of oil fields, convection and porosity modeling (IVC-SEP) • Class formalism; Adapted multi-components approach, Ternary models (MRC) Diffusion Coefficients in Crude Oil

  9. Diffusion Coefficients in Crude Oil - DCCO • First flight in NASA Space Shuttle in June 1999. • Measurements of diffusion coefficients in binary and ternary liquids (9 samples): DCCO will measure diffusion coefficients in 9 different samples containing: • Dodecane • Isobutylbenzene • Tetrahydronaphtalène Diffusion Coefficients in Crude Oil

  10. Experiment principle The introduction of ternary mixture A into a column of ternary mixture B is monitored using a Mach-Zehnder interferometer. The interferometer measures very small variations of refractive indexes at two different wavelengths. Diffusion Coefficients in Crude Oil
