ABSTRACT:
A pressure swing adsorption type gas separator system comprises an adsorption column filled with an activated carbon adsorbent and supplied with a compressed air for producing a nitrogen product gas by removing oxygen from the supplied air as a result of adsorption of oxygen on the activated carbon, a first valve for controlling the supply of compressed air to the adsorption column, a second valve for controlling release of oxygen adsorbed on the activated carbon from the adsorption column to the exterior of the gas separator system, and a third valve for controlling delivery of the product gas in the adsorption column to a tank. In operation, the supply of compressed air to the adsorption column, the removal of oxygen from the supplied air by the adsorption, delivery of the nitrogen gas thus obtained to the tank, and release of adsorbed oxygen to the exterior of the gas separator system are performed repeatedly with a predetermined cycle time. The gas separator further comprises an oxygen meter for measuring the concentration of oxygen in the nitrogen gas in the tank and a controller for controlling the cycle time responsive to the level of oxygen concentration in the nitrogen gas in the tank.
