Component adjusting device for liquefied fuel gas for Laurie

摘要

To provide a component adjustment apparatus for liquefied fuel gas shipped by a lorry car which efficiently separates a heavy component and re-mixes the heavy component while adjusting its ratio without increasing power consumption.SOLUTION: A component adjustment apparatus for liquefied fuel gas shipped by a lorry car of the present invention comprises: a liquefied fuel gas line 7 in which liquified fuel gas flows; and two lines branched from the liquefied fuel gas line 7, a first line 9 for supplying low calorific value gas with a diluted heavy component and a second line 13 for supplying high calorific value liquefied fuel gas with an enriched heavy component to a lorry tank 23 mounted on a lorry 11. The first line 9 comprises a booster pump 15, a vaporizer 17 and a membrane separation device 19. The second line 13 comprises a gas-liquid mixing device 21 for mixing the enriched gas with an enriched heavy component into the liquefied fuel gas and a decompression device 25 for decompressing a gas-liquid mixture obtained by the gas-liquid mixing device 21. The apparatus of the present invention also comprises an enriched gas supply line 27 for supplying the enriched gas with an enriched heavy component separated by the membrane separation device 19 to the gas-liquid mixing device 21; and a return gas line 29 for returning vaporized gas vaporized in the lorry tank 23 to a LNG tank 3.SELECTED DRAWING: Figure 1
