DEVICE AND METHOD FOR ANALYSING QUALITY INDICATORS OF NATURAL GAS PRODUCT AND USE THEREOF Russian patent published in 2025 - IPC G01N30/02 

FIELD: gas industry; measuring.

SUBSTANCE: invention relates to a device and a method for analysing quality indicators of a natural gas product. Device has a sample loading unit and first, second, third, fourth and fifth column chromatographic analysis systems connected in parallel. First chromatographic column analysis system is configured to separate sulphides from natural gas. Second chromatographic column analysis system is configured to separate hydrocarbons having C₃ and higher from natural gas. Third chromatographic column analysis system is configured to separate oxygen, nitrogen, methane and carbon monoxide from natural gas. Fourth chromatographic column analysis system is configured to separate carbon dioxide and ethane from natural gas. Fifth chromatographic column analysis system is configured to separate helium and hydrogen from natural gas. Each chromatographic column analysis system is equipped with a quantitative tube, a tube for carrier gas and a chromatographic column. Quantitative tube is configured to store a natural gas sample. Carrier gas tube is configured to deliver the carrier gas to the chromatographic column analysis system in order to subject the natural gas sample in the quantitative tube to components inside the chromatographic column. Sample loading unit is connected to quantitative tubes of the first, second, third, fourth and fifth chromatographic column analysis systems with possibility of controlled connection/disconnection for supply of natural gas sample to quantitative tubes of the first, second, third, fourth and fifth chromatographic column analysis systems. Each chromatographic column analysis system is connected to the corresponding detector, respectively.

EFFECT: design of an analysis device and an analysis method, which simplify obtaining quality indicators of a natural gas product.
