METHOD AND DEVICE FOR OBTAINING GASEOUS HYDROCARBON FLOW FROM LIQUEFIED HYDROCARBON FLOW Russian patent published in 2012 - IPC F25J1/02 

FIELD: machine building.

SUBSTANCE: method for obtaining gaseous hydrocarbon flow from liquefied natural gas flow is implemented at the plant for generation of liquefied natural gas, which contains accumulating tank, gas-liquid separator located in the direction before accumulating tank, expansion device located in the direction before gas-liquid separator and in the direction after liquefaction unit. Method involves liquefied hydrocarbon flow supply to inlet of accumulating tank, discharge of some part of liquefied hydrocarbon from accumulating tank, supply of some part of discharged hydrocarbon flow to pipeline point located downstream of expansion device and upstream of inlet of accumulating tank, obtaining gaseous hydrocarbon flow from flow of discharged liquefied hydrocarbon and discharge of gaseous hydrocarbon flow as fuel gas; at that, some part of gaseous hydrocarbon flow is compressed; integration of some part of discharged liquefied hydrocarbon with some part of compressed gaseous hydrocarbon, and passage of integrated flow along the direction after expansion device.

EFFECT: use of invention allows increasing the quantity of the obtained fuel gas.
