JEFRI DBR system

DBR-JEFRI Cell for supercritical extraction, VLLE and VLS and conventional PVT analysis of gas condensates and black oils. Maximum pressure 700 bar and maximum temperature 180°C.

Detailed description
The apparatus for measuring solubilities and phase equilibrium consist of a phase. Equilibrium view cell with a piston, an air bath, a displacement pump, high-pressure. Pycnometers, rocking mechanism and filling, cleaning and sampling lines.
For separation of the sample in the pycnometer a gasometer is used.
