ABSTRACT:
Improved process and apparatus for drying oxygen-containing streams, particularly wet air streams, are provided wherein these streams are contacted with glycols. The regeneration of glycols and in particular the removal of oxygen from the glycols is effected in a first step at a temperature below the oxidation temperature of the glycols, and then the removal of water from the glycols is effected in a second step, preferably by heating the wet glycols.
