VSA Oxygen Generator

Operating Principle for the VSA Oxygen Generator

Low Pressure compressed air is introduced into an adsorber vessel by means of a Positive Displacement Blower. The air is directed to flow through a Zeolite adsorber bed. As the air passes through the Zeolite, Nitrogen is preferentially absorbed from the air stream, leaving the enriched Oxygen to pass through. Once the bed becomes saturated with Nitrogen, the air flow is stopped and the pressure reduced, by stopping the blower and reversing its direction. By this method, one single blower can act as a feed-air source of compressed air, as well as a vacuum compressor. As the air pressure is reduced in the adsorber vessel, the Nitrogen that was adsorbed on the Zeolite is released and exhausted from the vessel, eventually leaving a fresh adsorber bed, ready to be pressurized again. This cycle is continued over and over to produce the necessary amount of Oxygen, as required. If the Oxygen product flow is required to be a continuous and steady flow, a buffer vessel is utilized in the process output.
