DEVICE FOR DETERMINING CONTENT OF DISPERSED LIQUID IN GAS FLOW Russian patent published in 2025 - IPC G01N9/36 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry and can be used to control efficiency of gas cleaning in oil and gas separators. Device for determining the content of dispersed liquid in a gas stream comprises a sample line of the analysed gas with the possibility of being connected at a point at which the thermobaric conditions provide its single-phase gaseous state, which is configured to reach the plug, heat carrier gas supply line, control unit, connected in series: unit of heat exchangers, separation unit, hydrate formation inhibitor supply unit. Control unit includes control valves installed at the inlet and outlet of the analysed gas line, and a control valve installed at the inlet of the heat carrier gas supply line. Unit of heat exchangers contains two serially installed heat exchangers on flow of analysed gas, which are made with possibility of supply of heat carrier gas to their annular spaces by two parallel flows and output of heat carrier gas to plug. Separation unit includes a filter-separator and a measuring tank for liquid collection, structurally combined into a single structure, a bypass line, shut-off valves and instrumentation, which are represented by pressure and temperature meters. Hydrate formation inhibitor supply unit contains a reservoir for the inhibitor, a drop indicator, a control valve and a shut-off valve. At the outlet of the line of the analysed gas, control and measuring devices are installed, in the form of a gas meter, pressure and temperature meters; said equipment represents a research unit which is mounted and fixed on the vehicle.

EFFECT: increasing the reliability of obtaining results for the quantitative determination of dispersed liquid in a flow of gas purified in separators.
