Installation til produktion af oxygen af høj renhed

摘要

The invention relates to an installation for producing oxygen of high purity, which is advantageously installed in a transportable container ( 21 ), comprising: an upstream pressure-swing-adsorption (PSA) device (A₁) containing a zeolite sieve; a downstream PSA device (A₂) containing a carbonaceous sieve; in a loop between the two devices, a permeation device (P) capable of separating oxygen form argon; and a medium-pressure oxygen compressor ( 20 ). The invention is used for producing oxygen of high purity on-site, typically in isolated locations.
