NITROGEN COPPER DE-OXO MODEL

DESCRIPTION

Another type of DE-OXO unit is used for additional cleaning using copper catalyst for removal of extra Oxygen, the moisture and Hydrogen contents and maintained upto 1PPM level. This Ultra pure nitrogen gas finds application in electronic, synthetic fiber and optical fiber industries. These systems are installed where along with Oxygen & Moisture, Hydrogen is not derived in the Nitrogen gas Stream.

This DE-OXO unit needs two externally heated filled columns with copper as catalyst for the endothermic reaction. The loaded copper bed can be regenerated by adding Hydrogen during the regeneration step. For this two step process (Deoxidization and regeneration), two reactors are necessary to achieve a continuously operating DE-OXO system. The nitrogen form the PSA System with the remaining oxygen passes one of the reactors without adding Hydrogen. On passing through the reactor, the oxygen is removed by reacting with the copper surface, The advantage of the DE-OXO unit based on the copper is that the high purity nitrogen leaves the unit absolutely dry & without any remaining Hydrogen.

A typical representation for the plant is shown in the figure 1.3 below.
