<p>In this installation of the pump type, part of the high-pressure air used for vaporising and heating the oxygen is supercharged (compressed) by at least blower (at 30, 31) before being at least partly liquified (at 16) in the heat-exchange line (2) then, after pressure reduction (expansion) (at 17) introduced into the double column (1). Application to the production of oxygen under at least 13 bar. <IMAGE></p> |
