A method of passivating the interior surface of a gas storage vessel to protect the surface against corrosion. The interior surface of the vessel is first dehydrated and then evacuated. A silicon hydride gas is introduced into the vessel. The vessel and silicon hydride gas contained therein are heated and pressurized to decompose the gase. A layer of silicon is deposited on the interior surface of the vessel. The duration of the silicon depositing step is controlled to prevent the formation of silicon dust in the vessel. The vessel is then purged with an inert gas to remove the silicon hydride gas. The vessel is cycled through the silicon depositing step until the entire interior surface of the vessel is covered with a layer of silicon. The vessel is then evacuated and cooled to room temperature.

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.

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bottom portion of a container system for storage and/or transport until a target pressure is reached after which gas is withdrawn from an upper portion of the container system at a rate to maintain the target pressure while the compressed fluid is injected in the bottom portion.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.

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.
