METHOD OF SAMPLING LIQUEFIED NATURAL GAS (LNG) Russian patent published in 2020 - IPC G01N1/14 G01N1/24 

FIELD: gas industry.

SUBSTANCE: invention relates to production and preparation of liquefied natural gas (LNG) samples for analysis, in particular to the LNG sample pumping into the sampler, and can be used in the cryogenic gas industry. Method involves sampling LNG, its regasification, maintaining the required pressure and transporting one part of the sample to a gas chromatograph for chemical analysis, and the other part for compression and pumping into the constant pressure sampler for analysis in laboratory conditions, which is performed by the liquid-gas ejector due to the pressure difference of the LNG flow, which is supplied along the line connected to the probe and the LNG process pipeline for supply to the ejector, and the stream of the regasified sample, which creates the rarefaction area in the mixing chamber of the liquid-gas ejector and provides the LNG supply.

EFFECT: preventing change of the initial chemical composition of the sample, as well as reducing the volume of the sample subjected to regasification.
