Abstract:
1. A device for sampling and vaporizing liquefied natural gas, comprising: a circuit comprised of: wherein said vaporization chamber comprises, successively along said circuit, a first portion with a convergent cross-section and a second portion with a divergent cross-section shaped so as to vaporize said sample, under supercritical conditions at a pressure higher than 80 bar generated by vaporization and without fractioning of said sample, and wherein said vaporization chamber comprises an inlet at a level of said convergent cross-section, and an orifice with a varying opening, said orifice being so sized as to limit vaporization pressure to a maximum of 90 bars in conjunction with a fixed orifice at an outlet of said divergent cross-section, and at said outlet of said vaporization chamber.
