Separation of a CO2+CH4 gas mixture by gas hydrate formation: An experimental study

The purpose of this study is to gather information about the gas hydrate formation when an equimolar gas mixture of CO2 and CH4 is injected on top of a liquid aqueous phase at 275.85 K and various pressures ranging between 2.5 and 6.0 MPa . With these experiments it can be determined if there is preferred gas hydrate formation with CO2 or CH4....

Modelling CO2 Foam Displacements for Enhanced Oil Recovery

Increasing demand for oil in the near future implies the need for Enhanced Oil Recovery (EOR) methods to produce the remaining oil after primary and secondary production. Miscible gas injection has an excellent microscopic sweep efficiency; however due to density difference, high gas mobility and reservoir heterogeneity, the macroscopic sweep...
