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.

Load following single bed reversing blower adsorption air separation system

A mixed gas is separated with collection of at least one constituent gas. An inlet leads to a blower or other gas compression element through a valve. This blower feeds a chamber which contains media which selectively adsorbs the constituent gas to be collected, such as nitrogen from air. An exhaust from the chamber leads to an exhaust through a check valve. The blower can be reversed after nitrogen has been adsorbed within the chamber to desorb nitrogen and deliver nitrogen back through the blower. The inlet valve is closed after blower reversing and a separate diversion pathway is opened so that nitrogen is delivered from the blower to a nitrogen collection region. A variant system also includes an oxygen collection region on a side of the chamber opposite the blower for collection of both nitrogen and oxygen separated from air simultaneously, or collection of other constituent gases.
