<p>Method of increasing the content of at least one desired constituent in a gas containing a plurality of constituents, an installation for applying a method of this kind, and air enriched with oxygen by the application of this method. A pressure swing adsorption process and installation for carrying out said process are described. In the process according to the invention a temperature gradient in one chamber, formed in a plurality of cycles, is compensated by a gradient in an adjoining chamber by appropriate regulation of the flow in each chamber. At a certain moment in time the flows in two adjoining chambers will be countercurrent if in both chambers adsorption or desorption takes place and co-current if the processes in both chambers are different, i.e. one adsorption and one desorption. Also an installation embodying above process is described.</p> |
