Abstract: Two LNG storage tanks receive LNG from a fill station. The two storage tanks are connected to an overflow tank into which the LNG flows during pressurization of the system. The overflow tank is connected to the use device, i.e. the vehicle's engine, through a heat exchanger to provide high pressure natural gas thereto. The fill station initially delivers LNG to the two storage tanks until the tanks are substantially filled with LNG whereupon the fill station automatically stops delivery of LNG and begins to deliver natural gas vapor to the storage tanks until the pressure in the system reaches a predetermined maximum that is equal to or greater than the pressure required by the use device. During the pressurization of the system some of the LNG in the two storage tanks is forced into the overflow tank by the incoming natural gas vapor.

Abstract: The fueling station of the invention consists of a vacuum insulated storage tank for storing large quantities of LNG at low pressure. A delivery line connects the LNG in the storage tank with a fill line to engage the use device such as a vehicle's fuel tank at the fueling station. A meter is provided to deliver a metered amount of LNG to the vehicle. A pump is used to sub-cool the LNG and convey it from the storage tank to the delivery hose and an eductor is provided to gradually draw vaporized LNG from the storage tank into the delivery line. The fill line, pump, eductor and delivery hose are vacuum jacketed to prevent vaporization of the LNG. A circulation loop is provided to sub-cool the pump, eductor and meter prior to delivering LNG to the vehicle in order to ensure that vaporized natural gas is not delivered to the use device. In an alternate embodiment a heat exchanger using LN.sub.2 or other coolant can be used in place of the pump to sub-cool the LNG.
Abstract translation: 本发明的加油站由用于在低压下储存大量LNG的真空绝热储罐组成。 输送管线将储罐中的LNG与填充线连接,以在加油站处接合诸如车辆燃料箱的使用装置。 提供一个仪表以向车辆输送计量的液化天然气。 使用泵来冷却LNG并将其从储罐输送到输送软管,并且提供喷射器以逐渐将蒸发的LNG从储罐吸入输送管线。 填充线,泵,喷射器和输送软管是真空夹套,以防止LNG的蒸发。 提供循环回路以在将LNG输送到车辆之前对泵,喷射器和仪表进行次冷,以确保蒸发的天然气不被输送到使用装置。 在替代实施例中,可以使用使用LN2或其他冷却剂的热交换器来代替泵来对LNG进行二次冷却。
