Abstract

A process for recovery of oxygen from a cryogenic air separation system in which measured data at the input or output of a latent heat exchanger and measured data within a column is compared with preselected data so that any deviation therebetween can be used to produce a signal that will vary the input parameters of the system until there is no deviation between the measured data and preset data thereby insuring that the system will operate under preselected optimum conditioning.
