Abstract:
An apparatus for protecting a functional fluid includes an inner pliant shell disposed inside an outer pliant shell. A sealed space separates the inner and outer pliant shells and the inner pliant shell defines a variable volume for receiving the functional fluid. A filler fills the sealed space.
Abstract:
A method and system for supplying additional hydrogen from a reservoir of stored hydrogen in a salt cavern to a hydrogen pipeline to assist in meeting customer demand for hydrogen is provided. Contaminants introduced while the stored hydrogen stream is in the salt cavern may cause the crude hydrogen stream to not have the required product purity specification. The stored hydrogen is removed from the salt cavern as a crude hydrogen stream and thereafter diluted with higher purity hydrogen formed from the pipeline to form a hydrogen product stream at or below the product purity specification. The hydrogen product can be formed without removal of any of the contaminants in the crude stream, thereby creating a more cost effective and simplified supply process compared to conventional processes employing a salt cavern for hydrogen supply.
Abstract:
A water sensing assembly includes: a valve box securely mountable on an underground water pipe; a sensor mounted inside the valve box, the sensor configured to sense a property of water within the underground water pipe; a top section connected to the valve box; and an electrical communication device mounted at a top portion of the adjustable top section such that the electrical communication device is positioned at or near the surface of the ground.
Abstract:
Systems and methods of measuring properties of water in a water distribution system are provided. An analysis system, according to one embodiment, comprises a plurality of water sensors connected at various points to the water distribution system, each of the plurality of water sensors configured to measure a property of water. The analysis system also includes a computer server configured to communicate with the plurality of water sensors via a network and receive water measurement data from the plurality of water sensors. The computer server comprises a processor, a database configured to store the water measurement data, and a system health monitoring module configured to evaluate the health of the water distribution system to obtain health data. The analysis system further includes at least one client device configured to communicate with the computer server via the network and receive the health data from the computer server.
Abstract:
A polymer manhole base comprising a base portion having an upper surface. An annular sidewall may extend upward from the base portion and may circumscribing the upper surface. The annular sidewall may have a diameter. A thickness of the annular sidewall may less than 1/12th of the diameter.
Abstract:
A method for transport of natural gas through a pipeline from a gas field to a terminal, where there is a risk of condensation of heavy hydrocarbon components in the pipeline during the transport, wherein dry gas is added to the natural gas to reduce the cricondentherm and the cricondentherm of the gas and thus prevent condensation in the pipeline, is described. A plant for carrying out the method is also described.
Abstract:
A booster station having an integral foundation preinstalled prior to shipment to an installation site. An above ground pump enclosure houses at least one pump. Each pump has a pump inlet for receiving water and a pump outlet for discharging water at a predetermined pressure. A relatively rigid concrete foundation is integral to the pump enclosure. The foundation has an inner wall surface forming a chamber, an outer wall surface, a top wall supporting the pump enclosure, and a foundation floor opposite the top wall having an opening therein for allowing drainage of fluid from the chamber. The foundation has at least one inlet port for receiving water and at least one outlet port for discharging water to a water transport system. The inlet and outlet pipes are connected to the foundation ports at a first end and to the purrip at a second end. The inlet and outlet pipes include a relatively flexible synthetic rubber boot located at the first end that extends through the foundation outer wall surface. The pipe is adapted to be connected to the water transport system. A plurality of pipe restraints rigidly secure the inlet and outlet pipes within the foundation. Non-compactible material such as pea gravel may fill the chamber.
