Abstract

The aim of this project was the characterisation of transition zones of a real oil/CO(2)-system occurring during displacement processes with regard to chemical and physical properties as well as flow behaviour. Studies of transport phenomena were included, in order to acquire information about the mechanism for the stabilisation of flood fronts near the minimum miscibility pressure (MMP). Extensive PVT-studies on a real oil/CO(2)-system were carried out, including measurements of interfacial tensions and determinations of partition coefficients of characteristic components from the classes of n-alkanes, alkylbenzenes, alkylnaphthalenes, polycyclic aromatics, isoprenoids and sulphur-containing heteroaromatics. A new experimental device for steady and unsteady state experiments was developed, including a novel high pressure interface for an on-line coupling of the high pressure flood equipment with GC/MS couplings capable of on-column injections. The interface allows a continuous sample flux down to 1.0 E-5 cm3/s at an inlet pressure of 40 MPa.
