Introduction

The De-Oxo Model Nitrogen Gas Plant is an advanced nitrogen purification solution designed to produce ultra-high purity nitrogen gas up to 99.9999%. This system is widely used in industries where extremely low oxygen levels are critical for product quality and process safety.

Manufactured by AmsaAir Engineering Pvt. Ltd., the De-Oxo Nitrogen Plant ensures consistent performance, low operating cost, and long service life.

What is a De-Oxo Nitrogen Gas Plant?

A De-Oxo Nitrogen Gas Plant is a secondary purification unit used after a PSA or Membrane Nitrogen Generator. It removes residual oxygen present in nitrogen gas to achieve ultra-high purity.

In this process, a small and controlled quantity of hydrogen gas is injected into the nitrogen stream. Inside the De-Oxo reactor, oxygen reacts with hydrogen in the presence of a catalyst and converts into water vapor, which is later removed using a high-efficiency gas dryer.

Chemical Reaction:
O₂ + 2H₂ → 2H₂O

The result is dry, oxygen-free, high-purity nitrogen gas suitable for critical industrial applications.
