Systems and methods of monitoring and controlling the performance of a gas fractionalization apparatus

A gas fractionalization apparatus, comprising:

• a compressor which compresses a gas, such as air, to provide an output gas;
• a PSA unit which receives and processes the output gas from the compressor to produce a product gas;
• a sensing device which measures the pressure of the product gas;
• and
• a feedback mechanism which controls the pressure of the product gas by varying one or more parameters of the compressor in response to changes in the pressure of the product gas.

A gas fractionalization apparatus, comprising:

• a compressor which compresses a gas, such as air, to provide a pressurized gas;
• means for processing the pressurized gas to produce a product gas;
• means for containing the product gas;
• and
• means for controlling the pressure of the product gas in the container means,
• said control means comprises a means for sensing the pressure of the product gas and a means for adjusting one or more parameters of the compressor in response to changes in the pressure of the product gas so as to maintain the pressure at one or more pre-selected levels.
