Abstract:

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.

Abstract:

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.

Abstract:

An exemplary single bed reversing blower adsorption based air separation unit is configured to follow the Oload placed thereon by adjusting flow rates therethrough and power consumption. At least one and preferably multiple pressure sensors sense Opressure within an Ostorage 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 Oload is thus achieved without driving the air separation unit into operational conditions outside of design and also maintaining optimal power consumption for the Oproduced, such that efficiency is maintained over a large turndown ratio.

International Classification:

Abstract:

A single bed reversing blower vacuum swing adsorption air separation unit includes a purge recovery tank. This purge recovery tank is joined to an Osupply line downstream of the adsorber vessel or directly to the adsorber vessel opposite an inlet thereof. The purge recovery tank collects a purging charge of mostly Ogas towards the end of a production phase for the air separation unit. This purging charge is held by the purge recovery tank while the reversing blower reverses and the material within the adsorber vessel is recharged. Around the time that the reversible blower is re-reversed to return to a production phase, the purge recovery tank is opened to allow mostly Ogas from the purge tank to quickly flow back into the adsorber vessel which has a vacuum drawn thereon, to allow the air separation unit to quickly return to its production phase.

International Classification:

B01D 53/047

Abstract:

A multi-unit system combines multiple single bed reversing blower vacuum swing adsorption air separation units together. The units feed a common Osupply such as a system buffer tank. Demand is monitored and a number of individual units are brought online sufficient to meet demand. If demand exceeds supply, a further unit is brought online. If demand drops below supply by an amount greater than output of a single unit, then a longest operating unit is taken offline. The multi-unit system thus meets demand through utilization of multiple separate units in a highly redundant and highly reliable and scalable fashion.
