<p>The invention relates to a process for the advanced recovery of liquid oxygen upon the air fractioning. According to the invention, the recovery process consists in recovering a part of the oxygen contained in the residual fraction in the nitrogen-oxygen separating column, by partial condensation thereof at a temperature of - 184 C and at a pressure of 1.6 at., based on an amount of gaseous nitrogen flux, produced in the installation followed by introducing the condensate into the reboiler of the fractionating column, where it is heated to - 179 C and it is purified to 99.7 % O2 mass.</p> |
