Abstract
Apparatus for measuring thermodynamic characteristics of a hydrocarbon sample, comprising at least one measurement cell (12; 14) intended to be selectively connected to a gas gauge (82); the gas gauge being capable of being selectively connected to a gas recovery assembly (98) and a liquid storage assembly (114), the measurement cell (12; 14) comprising a piston/cylinder assembly (16; 20; 18; 22), the piston being movable in the cylinder under the action of a jack (24; 26).
Claims5
Apparatus for measuring thermodynamic characteristics of a hydrocarbon sample, comprising at least one measurement cell for measuring pressure, volume and temperature characteristics of the hydrocarbon sample, said measurement cell being selectively connected to a gas gauge for measuring pressure, volume and temperature characteristics of a gaseous sample received from said measurement cell;
- said gas gauge being selectively connected to a gas recovery assembly and a liquid storage assembly for recovering and storing gas and liquid from said gas gauge for subsequent analysis, said measurement cell comprising a piston/cylinder assembly, the piston being movable in the cylinder under the action of a jack and a gas/liquid detection apparatus arranged in said measurement cell, said detection apparatus including a tubular element made of transparent light transmitting material, comprising a conical end projecting inside the cell, the tubular element being provided with an input and an output for a light signal.
