ABSTRACT:
Method and apparatus for using a centrifugal compressor during the exhaust portion of the cycle in a pressure vessel used to separate components from a gaseous mixture by pressure swing or vacuum swing adsorption. Energy input to the motor of an electrically driven motor-compressor is minimized at a time when the exhaust portion of the cycle is initiated allowing rotation of the compressor wheel to decelerate by contact with the absorbed gaseous components until the speed of rotation of the compressor wheel matches the efficient compression ratio for the compressor and then reenergizing the motor to increase the speed of rotation of the compressor wheel according to the best efficiency curve for said compressor until a full outlet to inlet pressure ratio across said compressor is achieved.
