Abstract
In an air separation process using pressure swing adsorption techniques, for providing high purity oxygen, two sections are employed, in either order, one comprising beds of molecular sieve carbon and the other comprising beds of zeolite molecular sieve. Air is fed to a first of the sections which provides an oxygen-rich gas stream as feedstock for the next section where further enrichment takes place providing a more enriched oxygen product stream and a recycle stream, enriched in oxygen relative to the air but to a lesser extent than the product stream, for return to the first section as part of the feedstock thereof. The zeolite sieve section effects a separation between oxygen and nitrogen while the carbon sieve section effects a separation between oxygen and argon and the processes performed at each section are integrated in such a manner as to minimise power consumption. <IMAGE>
