Fluid storage and dispensing system

A fluid storage and dispensing system comprising a vessel for holding a fluid at a desired pressure. The vessel has a pressure regulator, e.g., a single-stage or multi-stage regulator, associated with a port of the vessel, and set at a predetermined pressure. A dispensing assembly, e.g., including a flow control means such as a valve, is arranged in gas / vapor flow communication with the regulator, whereby the opening of the valve effects dispensing of gas / vapor from the vessel. The fluid in the vessel may be constituted by a liquid that is confined in the vessel at a pressure in excess of its liquefaction pressure at prevailing temperature conditions, e.g., ambient (room) temperature. In another aspect, the vessel contains a solid-phase sorbent material having sorbable gas adsorbed thereon, at a pressure in excess of 50 psig. The vessel may have a >1 inch NGT threaded neck opening, to accommodate the installation of an interior regulator.

Valve with smart handle

A valve with a smart handle including a memory module to log relevant data. A sensor on the handle determines when the valve is open, and this triggers the start of timers and recording of the “open” event in a log in the memory module. When the valve is closed, the sensor triggers stopping of the timers and recording of the “closed” event in the log. The timer information is used to calculate the duration of the time “open” event, and this, together with the actual date and time of the opening and closing of the valve are recorded in the log. Other relevant information, such as cylinder fill date, cylinder I.D. number, batch number, and patient name or account number may also be logged in the memory module. The log of the events and the corresponding dates and times may be used to prepare invoices for billing gas treatments, for inventory control, and for other record-keeping and control functions.

Apparatus and method for flowing compressed fluids into and out of containment

Methods for loading a compressed fluid, such as natural gas, into and discharging the compressed fluid out of containment are provided. The compressed fluid is injected into a bottom portion of a container system for storage and / or transport until a target pressure is reached after which gas is withdrawn from an upper portion of the container system at a rate to maintain the target pressure while the compressed fluid is injected in the bottom portion. The compressed fluid is cooled through an expansion valve and by refrigerated chillers or by injecting a cold liquid of the same chemical composition as the compressed fluid, such as liquid natural gas, into the compressed fluid prior to injection into the container system. Withdrawal or discharge from the container system to a receiving facility begins with blow down from the bottom portion of the container system without a displacement fluid and continues until pressure falls below an acceptable differential pressure. The discharge stream is passed through a separator and a light gas from the separator is pressurized and injected into an upper portion of the container system to drive the compressed fluid out the bottom. The light gas is pressurized using either a compressor or a heated tank system, where two vessels operate in parallel, trapping and heating the light gas and then discharging to the container system from one while filling the other and alternating the operation between the two.

Modular fluid flow system with integrated pump-purge

This disclosure describes a modular, monolithic pump-purge system which can be integrated into a modular, monolithic fluid handling system without creating a closed tolerance loop. In particular, the pump-purge system comprises a plurality of valves mounted on a modular and monolithic manifold which can be attached to the modular, monolithic fluid handling system. At least a portion, and preferably all of the fluid transfer conduits necessary for either applying a vacuum (or other evacuation means) to a fluid handling system conduit which is to be evacuated (pumped), or for transfer of flushing fluid within a conduit (purging) are present within monolithic manifolds of the fluid handling system. The modular, monolithic manifold of the pump-purge system contains openings and fluid flow conduits which correspond with openings and fluid flow conduits of the modular, monolithic fluid handling system, to enable evacuation or flushing of a selected fluid flow conduit within the fluid handling system. To avoid the formation of a closed tolerance loop, it is necessary that the pump-purge manifold or a portion of the modular, monolithic fluid handling system manifold to which it is attached be sufficiently free-floating to permit making of all necessary connections without creating stress which can lead to an increased rate of corrosion or failure of the connection. In a preferred embodiment gas handling system, the gas handling flow lines which make up the system are comprised of individual sticks of gas handling elements, each of which is attached to the manifold of the pump-purge system so that it is free-floating.

Liquid and compressed natural gas dispensing system

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.
