DEVICE FOR COOLING AND SEPARATION OF LIQUID HYDROCARBONS RELEASED DURING GAS COMPRESSION Russian patent published in 2014 - IPC F25J3/06 

FIELD: machine building.

SUBSTANCE: device for cooling and separation of liquid hydrocarbons released during gas compression comprises a refrigerator-condenser fitted by coolant supply/discharge lines, and lines to supply the said liquid hydrocarbons, to withdraw compressed gas, and at least one line to withdraw condensate. A fractional column fitted by a heat and mass exchanging section, for example, of radial-spiral type, and a throttling valve is used as the refrigerator-condenser. The throttling valve is installed at the discharge line for the above liquid hydrocarbons and is connected to a stabiliser by a throttled condensate supply line. The stabiliser is equipped by a distributing unit, a heat and mass exchanging section, for example, of radial-spiral type, a line to supply cooled liquid hydrocarbons from the stabiliser to the fractional column, and a line to withdraw stabilisation gas.

EFFECT: increased output of compressed gas, reduced losses of C₅₊ hydrocarbons with the compressed gas, and production of stable condensate with specified pressure of saturated vapour.
