Abstract: The device for sampling and vaporizing liquefied natural gas includes a circuit provided at one end with a device for collecting a sample of liquefied gas and conveying the sample to a measurement device. The circuit includes and passes through a device for vaporizing the sample. The device for vaporizing includes at least one vaporization chamber having a first convergent section portion and a second divergent section portion and shaped so as to vaporize the sample under supercritical conditions at a pressure of greater than 80 bar without fractionating. The vaporization chamber includes, at the entrance of the first convergent section portion, a port with a variable opening. The port is sized so as to limit the vaporization pressure to a maximum of 90 bar in conjunction with a fixed opening at the outlet of the second divergent section portion.
Abstract: The device for sampling and vaporizing liquefied natural gas includes a circuit provided at one end with a device for collecting a sample of liquefied gas and conveying the sample to a measurement device. The circuit includes and passes through a device for vaporizing the sample. The device for vaporizing includes at least one vaporization chamber having a first convergent section portion and a second divergent section portion being consecutive along the circuit and shaped so as to vaporize all of the sample under supercritical conditions at a pressure of greater than 80 bar without fractionating. The vaporization chamber includes, at the entrance of the first convergent section portion, a port with a variable opening. The port is sized so as to limit the vaporization pressure to a maximum of 90 bar in conjunction with a fixed opening at the outlet of the second divergent section portion.
