METHOD AND SYSTEM FOR STREAMING FLAME PHOTOMETRIC DETERMINATION OF CONTENT OF SULFUR-CONTAINING COMPOUNDS IN NATURAL GAS Russian patent published in 2024 - IPC G01N30/04 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a system for streaming flame photometric determination of content of sulfur-containing compounds in natural gas. System comprises a sampling device, a pressure relief system, a system of chromatographic columns and a flame photometric detector. Chromatographic column system comprises a boiling point column and a sulfur column. Sampling device is connected through a pressure release system to the boiling point column. Boiling point column and the sulfur column are connected to the carrier gas pipeline through a switching pipeline. Outlet of the boiling point column communicates with the inlet of the sulfur column through a switchable pipeline. Sulfur column outlet communicates with the boiling point column inlet via a switchable pipeline. Boiling point column and the sulfur column are connected to the flame photometric detector through a switchable pipeline.

EFFECT: providing the possibility of streaming determination of content of sulfur-containing compounds with high accuracy.
