Liquid-dissolved gas characterization facility and method

摘要

The invention particularly relates to a facility for characterizing liquid-dissolved gas.;In its most complete embodiment, this facility comprises a liquid collecting capsule (1) and a circuit of fluid with two branches (2, 3) including a plurality of valves (41-47), the first branch (2) making it possible to retain the liquid, and the second branch (3) making it possible to extract vacuum gases and including in particular a sealed joint section (31), a pumping facility (32), a variable volume enclosure (33), and pressure and temperature measurement means (34-37).

主权项

1. A facility for characterizing liquid-dissolved gas, this facility comprising at least a circuit of fluid including first and second branches, the first branch exhibiting a first end for the intake of the liquid and a second end being connected to the second branch, and each branch comprising at least a valve, wherein the first branch comprises, in series in this order between the first and second ends thereof, a first valve, a first container for collecting the liquid, a second valve designed to shut-off or establish a communication between the fluid input and said first container, and a vapor trap designed to trap a liquid vapor, wherein the second branch comprises a sealed joint section connected to the second end of the first branch, a third valve designed to shut-off or establish a communication between the first branch and the joint section, a pumping facility, a fourth valve designed to shut-off or establish a communication between the joint section and this pumping facility, a fifth valve designed to shut-off or establish a communication between the first branch and this pumping facility, said fifth valve being connected to the first branch between the first container and the vapor trap, a first variable volume enclosure, a sixth valve designed to shut-off or establish a communication between the joint section and said variable volume enclosure, measurement means connected at least selectively to the joint section and including at least a pressure sensor, a seventh valve making it possible to connect the joint section to the pressure sensor or to a pressurized inert gas bottle, and a liquid sampling capsule selectively connected to the first end of the first branch and whose said first valve controls the opening, in that the first container is temperature controlled and ultrasound emitting, and in that the measurement means comprise a temperature gauge.
