| titleOfInvention | Method and device for unloading liquid natural gas |
| abstract | The invention discloses a liquid natural gas unloading method and device, wherein the method comprises: connecting a first liquid inlet of a storage tank with a first liquid outlet of a tank truck; wherein, the first liquid inlet Set at the bottom of the storage tank; introduce the liquid natural gas in the tanker tank into the storage tank to gasify the residual liquid nitrogen in the storage tank; continue to introduce the liquid natural gas, when the liquid natural gas in the storage tank is When the liquid level of the liquid natural gas is raised so that the pressure in the storage tank reaches 0.3 MPa, the vaporized liquid nitrogen is discharged through the gas phase port of the storage tank. In the present application, by using low-temperature LNG to directly replace nitrogen, unnecessary waste of resources is avoided, and the replacement process is not only environmentally friendly, but also safe and reliable. |
