摘要： An exemplary single bed reversing blower adsorption based air separation unit is configured to follow the O2 load placed thereon by adjusting flow rates therethrough and power consumption. At least one and preferably multiple pressure sensors sense O2 pressure within an O2 storage region downstream of an adsorber vessel. These sensed pressures are utilized to generate control signals controlling flow rates at locations upstream of the compressor, such as at a reversible blower and an output compressor. Control loops for the blower and the compressor are independent of each other and have different time constants. Effective following of the O2 load is thus achieved without driving the air separation unit into operational conditions outside of design and also maintaining optimal power consumption for the O2 produced, such that efficiency is maintained over a large turndown ratio.

摘要： The adsorption based air separation unit includes an adsorber vessel containing media which selectively adsorbs water vapor and nitrogen preferentially over oxygen. The vessel includes an air entry spaced from an oxygen discharge. At least one dry air tap from the adsorber vessel is located between the entry and the discharge. When the adsorption media is fresh, air entering the adsorber vessel passes through enough of the adsorber vessel to have much of its water vapor removed and only some of its nitrogen removed. The vessel can include multiple taps sequentially further from the entry which can be selectively opened as the adsorption media becomes saturated with water vapor and nitrogen, so that dry air with much of its nitrogen still present can be further tapped from the adsorber vessel. The adsorber vessel thus facilitates production of both oxygen and dry air, such as for use as medical grade air.

摘要： An air separation unit includes an air inlet with a reversible blower downstream therefrom and an adsorption bed filled with adsorption media downstream of the reversible blower. The adsorption bed contains an adsorption media which preferentially adsorbs nitrogen over oxygen. An oxygen and argon output is located downstream of the absorption bed. At least a portion of the mixed gas of oxygen and argon is routed to a modular argon separator which separates out at least a portion of the argon to provide high purity oxygen to a high purity oxygen outlet. The argon separator can be configured as a molecular sieve filter to separate the argon from the oxygen or the argon separator can be in the form of a gas cooler and condenser which condenses liquid oxygen for storage and discharge as substantially pure oxygen.

摘要： A driving system for a reversing blower adsorption based air separation unit is configured to not only drive the reversing blower cyclically in a forward and in a reverse direction, but also to allow the reversing blower to coast during a portion of its operating cycle. While coasting, a pressure differential across the blower acts alone to switch the reversing blower between a forward and a reverse direction of operation. Less power is thus required. When coasting, the blower can also be configured to output power such as the drive motor functioning as an electric generator or by having a mechanical power input be driven by the blower for power generation and/or energy storage. Such a system beneficially utilizes the energy associated with the pressure differential across the blower for energy harvesting and to further accelerate cycle times for the reversing blower adsorption based air separation unit.

摘要： The housing is attachable to a high pressure fluid containing structure. A piston is provided within the housing, with the piston having a closed position and an open position. The closed position blocks an outlet vent of the relief device, with the open position allowing high pressure fluid to escape through the vent. The piston is biased toward the open position by the high pressure fluid, but is held in the closed position by a slide. The slide has a first position and a second position, with the first position holding the piston in the closed position. A spring biases the slide toward a second position, with a eutectic mass resisting movement of the slide to the second position. The eutectic mass is selected to have a melting point matching a maximum design temperature for the high pressure fluid containing structure. Should the eutectic mass melt, the high pressure fluid escapes.

The containers can be connected together at anchor points on the housings of both containers, making the nitrogen generator assembly more stable. The air preparation unit includes an absorption device and optionally includes one or a plurality of air compressor units. The cryogenic distillation unit includes a distillation column and associated heat exchangers. The air preparation and cryogenic distillation units connect through apertures in their respective containers and operate while being mounted in the containers.
