  • Liquid and compressed natural gas dispensing system
    Patent number: 7069730
    Abstract: A system dispenses both liquid natural gas (LNG) and compressed natural gas (CNG). A bulk tank contains a supply of LNG which is pumped to a smaller storage tank. After the storage tank is refilled, LNG from the bulk tank is pumped to a vaporizer so that CNG is produced. The CNG may be routed to the LNG in the storage tank to condition it. It is also used to recharge a pressurizing cylinder that is placed in communication with the head space of the storage tank when it is desired to rapidly dispense LNG to a vehicle. A bank of cascaded storage cylinders alternatively may receive CNG from the vaporizer for later dispensing through the system CNG dispenser. The CNG from the vaporizer may also be dispensed directly via the system CNG dispenser.
