Description

The educational Fluid Eval is a compact PVT cell designed for small volume PVT, thermodynamic properties and phase behavior studies of black oil and gas condensate samples. The PVT cell is composed of an efficient fluid mixer mounted on the piston, a dedicated visual head, two sampling valves, an accurate pressure transducer and an electric heater enabling a homogeneous temperature control. A digital camera system monitors the liquid/gas interface through the sapphire windows. During differential vaporization or flash liberation, the removal of the gas phase is facilitated by the full visibility of the gas/oil interface through the cell window. For oil studies, the cell is in an upright position, and is inverted for gas condensate experiments.
