METHOD FOR ISOKINETIC EXTRACTION OF PART OF OUTGOING GAS FLOW FROM SEPARATION AND ABSORPTION EQUIPMENT Russian patent published in 2024 - IPC G01F1/00 

FIELD: gas industry.

SUBSTANCE: invention relates to the gas industry and can be used in the technologies for preparation of the produced formation fluid of gas and gas condensate deposits of hydrocarbon material to the main transport for measurement of mechanical entrainment of liquid in drop form from the presented devices. Method includes extraction of part of gas flow coming out of separation and absorption equipment, from the straight section of the pipeline by implementing the isokinetic principle of sampling a portion of the flow in question, based on the relationship between the difference of the measured static pressures of the gas flow and the portion taken therefrom, moving along the straight section of the pipeline and the sampling device, with values of velocities of the considered media, taking into account the thermophysical properties of the gas flow and the part taken from it (density, dynamic viscosity, adiabatic coefficient) and arising hydraulic resistances to the movement of the sampled part of the gas flow along the sampling device, excluding the mismatch between the values of the speed of movement of the gas flow at the sampling point in the cross section of the straight section of the pipeline and the speed of the sampled part of the gas flow in the inlet cross section of the sampling device.

EFFECT: improving reliability of result of sampling part of gas flow and accordingly accuracy of measurement of mechanical entrainment of liquid in drop form with outgoing gas flows from separation and absorption equipment.
