<p>The method involves introducing an oxygen stream (123) into a vaporization space of a condenser (300). A gaseous oxygen stream (124a) is withdrawn from the vaporization space, and a gaseous oxygen product (124b) is obtained from the gaseous oxygen stream. A feed air stream (103) under first pressure is introduced into a liquefaction space of the condenser. A liquid airflow (104) is withdrawn from the liquefaction space, where pressure in a gas space of the vaporization space is less than 0.4 bar and higher than pressure in a gas space of a low pressure column (111) over a sump.</p> |
