SEPARATION PLANT FOR DETERMINATION OF POTENTIAL CONTENT OF LIQUID HYDROCARBONS IN NATURAL GAS Russian patent published in 2022 - IPC B01D3/14 

FIELD: oil, gas and coke-chemical industry.

SUBSTANCE: invention relates to oil and gas, petrochemical industry, in particular to installations for monitoring amount of hydrocarbon liquid, potentially formed in gas pipelines under different thermobaric conditions. Separation unit for determining potential content of liquid hydrocarbons in natural gas includes a separation unit connected to feed lines and natural gas removal, natural gas heating device, bypass line with filter cartridge with drier, mechanical impurities filter are installed in series on the natural gas supply line, the first pressure gauge, the reducer and the second pressure gauge, and on the natural gas discharge line the hydrocarbon dew point analyzer, the third pressure gauge and the gas flow meter are installed in series. Separation unit is immersed in a thermocryostat bath and consists of a first and a second separation unit, each of which consists of a coil and a separator equipped with a device for sampling degassed hydrocarbon condensate and having a syringe needle channel. Inlet and outlet shut-off and control devices of the first and second separation units are made with possibility of installation of sealing plugs on them.

EFFECT: high accuracy of determining potential content of liquid hydrocarbons in natural gas, as well as eliminating the effect of drop entrainment of liquid.
