Abstract:
The current invention discloses a fluid dispensing system, comprising a manifold defining a plurality of valve openings, each valve opening having an associated first fluid passageway adapted to be connected in fluid communication with one of a plurality of fluid supply containers, and a second fluid passageway adapted to be connected in fluid communication with a fluid storage container; and a plurality of valves, each valve disposed within one of the plurality of valve openings in the manifold and comprising a valve seat, a valve element comprising a seating surface, the valve element adapted for displacement along a longitudinal axis between a closed position, wherein the seating surface engages the valve seat, and an open position, wherein the seating surface is spaced from the valve seat, a valve inlet passageway disposed inside of the manifold and in fluid communication with the first fluid passageway, a valve outlet passageway disposed inside of the manifold and in fluid communication with the second fluid passageway, a first pressure sensing passageway adapted to be in fluid communication with the one of the plurality of fluid supply containers for communicating a first pressure to a first pressure sensing surface of the valve element, and a second pressure sensing passageway adapted to be in fluid communication with the fluid storage container for communicating a second pressure to a second pressure sensing surface of the valve element.
Abstract:
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bottom portion of a container system for storage and/or transport until a target pressure is reached after which gas is withdrawn from an upper portion of the container system at a rate to maintain the target pressure while the compressed fluid is injected in the bottom portion.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.
Abstract:
The present invention is referred to a transportable compressed natural gas supply system. This system is an integral solution for supplying compressed natural gas (CNG) to remote places that can not have access to the gas pipelines. It consists of storage modules (3), loading and unloading platform (4-32), a transport vehicle and a sequence of use of said modules (3). The modules (3) are formed by a protection cage with fibreglass lids having cylinders inside for the compressed natural gas. These cylinders are interconnected with pipes, and they also have lock, relief, excess and pressure gauge valves. Besides, these cylinders are separated from each other by rubber separators. The system is formed by loading and unloading platforms of the modules (3), a transport vehicle to help in replacing them and a sequence of use.
Abstract:
A gas storage and delivery system (20) for replacing gas lost from a pressurized container (11) or a carbonated beverage (32), or for introducing a gas such as oxygen into a beverage such as bottled water or a sports drink.
Abstract:
A high pressure storage and delivery system having a fail-safe vacuum actuated valve is provided. In particular, through the innovative design of the vacuum actuated check valve, the system can accommodate up to three times the volume of product in similar size cylinders.
Abstract:
A control device for controlling hydrogen flow of a hydrogen storage canister accommodated in a canister containing chamber includes a heating device which is connected to a heating fuel storage tank via a heating fuel supplying pipeline for conveying a heating fuel to a catalyst bed in the canister containing chamber and generating heat by combustion of the heating fuel at the catalyst bed. A blowing device provides an air flow to the canister containing chamber. A controller controls the operation of the heating device and the blowing device in correspondence to a temperature signal detected from an internal space of the canister containing chamber. The controller is coupled with a setting unit for setting various parameters which are stored in a parameter storage unit for controlling the controller.
Abstract:
Embodiments of vessels include personnel access provisions having welded or otherwise permanent connections that substantially reduce the potential for leakage into or out of the vessels by way of the personnel access provisions.
Abstract:
A fuel cell cartridge for containing fuel for fuel cells, comprising a polyester resin, wherein after the fuel is contained and preserved at 60°C for one week, a change of density at the bottom portion and the mouth portion is 0.01 g/cm 3 or less. Even when methanol of a high concentration is contained, the fuel cell cartridge maintains excellent appearance effectively preventing the occurrence of whitening in the container and, particularly, at the mouth portion and the bottom portion thereof, and effectively suppressing a decrease in the shock resistance.

Abstract:
A process of constructing a large diameter tank is provided. The process includes the step of providing a tank wall mandrel that has at least one drive wheel and at least one curved panel. Glass fibers are applied from a vertical winder to the curved panel in order to form a segment of a tank wall shell. Additional glass fibers are also applied to the curved panel at a location above the segment of the tank wall shell in order to form a unitary tank shell.
