摘要： A system for supplying gas, such as compressed air, from large capacity banks of storage containers having different pressure capacities. The gas is withdrawn first from the lowest pressure storage bank and later automatically from one or more successively higher pressure banks, if necessary to satisfy the demand. The demand pressure that is to be satisfied may be selected, and the system stops supplying gas automatically when the selected demand pressure is reached.

摘要： Each container in a bank of containers is individually charged with a gas in the order of the highest residual pressure remaining in the containers at the time charging is initiated. Gas withdrawal from the containers begins with the container at the lowest beginning pressure.

摘要： An energy recovery system places fans inside a pipe that carries natural gas or another fluid so that as the fluid passes over them, they rotate. As the fans rotate, they cause a generator to create electricity from the rotation. The fans thereby remove energy from the natural gas so that it reaches a pressure, velocity, or temperature that it is able to be consumed at.

摘要： A control system having a primary run and a trim run, each run including an inlet coupled to a main gas supply line, a pneumatically actuated control valve positioned downstream of the inlet, a pneumatic pressure controller having variable deadband adjustment, and an outlet feeding into a gas supply line to the facility. The control valve of the primary run is preferably high-capacity, while the control valve of the trim run is low-capacity. Further, the system and method for controlling gas supply to the facility has a total flow capacity through the primary run and trim run to the facility being defined by CX, which is the total flow capacity of the primary run (CP) plus the total flow capacity of the trim run (CT), and an actual gas flow to the facility being defined by FX, which is the actual flow of the primary run (FP) plus the actual flow of the trim run (FT) and wherein FX is less than CX, CT is less than CP and FX is either stable, increasing, or decreasing based on a demand from the facility.

摘要： Implementations are described for maintaining helium/air mixture within a tube in an evacuated tube transportation system. A first implementation includes a set of helium tanks uniformly fitted along the tube length, where helium is injected with controlled valves that open or close to maintain the desired level of helium. An operations control center (OCC) receives helium concentration levels in the tube and instructs a controller in the tube to release helium into the tube when detected levels of helium is lower than the desired level of helium. Another implementation is described where a capsule traversing the tube may have a source of helium gas that can be released into the tube. A hybrid approach is also described where helium can be released from a source within the tube and from another source within the capsule.

摘要： A duct intersection comprising a first duct portion and a second duct portion extending laterally from a side of the first duct portion. At least one flow modifier is mounted inside one of the first and second duct portions. The flow modifier is a contoured duct liner and/or the flow modifier includes at least one turning vane. The duct intersection may also include a transition portion extending between the first and second duct portions, wherein the transition portion has a length extending along a side of the first duct portion and a depth extending away from the side of the first duct portion, wherein the length is greater than a diameter of the second duct portion.

摘要： The natural gas temperature and pressure regulating system based on recovering pressure energy and absorbing heat from ultralow temperature ambient environment. A pressure driven heating system of pipeline natural gas pressure regulation or liquid natural gas regasification process. This system adopts vortex tube, ambient air heat exchanger and ejector that constitute the pressure driven heating unit to replace the existing heater. The two kinds of pressure driving devices of an ejector and a vortex tube are adopted, transmit the low temperature NG at the cold end of the vortex tube into the ambient air heat exchanger to absorb heat from the ambient continuously; at the same time, make temperature of the gas from the hot end of the vortex tube increase to meet the required temperature of pipeline directly, then achieve the purpose of no heater energy consumed.
