METERING PUMP LOCATED UPSTREAM AFTER THE PROBE AND ENSURING THE NATURAL GAS LIQUID CONDENSATE FLUID PHASE CHANGE COMPLETION DURING THE SAMPLE CONDITIONING Russian patent published in 2019 - IPC G01N30/06 

FIELD: technological processes.

SUBSTANCE: invention relates to the multi-phase fluid sampling system, such as the natural gas liquids (NGL) components products from the pipeline, and to the natural gas liquids condensate liquid sample single-phase state maximization method. Multiphase fluid sample extraction system contains the sampling probe, designed for the multiphase fluid from the pipeline extraction, sample conditioning unit, designed for the extracted fluid sample evaporation, and the evaporated sample maintaining in the temperature and pressure certain range, so as to prevent the dew point precipitation and the conditioned evaporated sample transfer to the downstream analyzer, and located in the line between the sampling probe and the sample conditioning unit metering pump, designed for the extracted fluid sample pressure increase and condensing so as to maximize the multiphase fluid sample transfer into the one completely liquid phase.

EFFECT: increase in the natural gas liquids (NGL) components products measurements accuracy and reproducibility, extracted during the sample analysis, as well as reduction in the pressurized fluid delay time before its introduction into the sample conditioning equipment.
