PSA Nitrogen + Methanol Inert Gas Generator
email feed help
Use of furnace atmospheres based on Methanol cracking has become widely acceptable as alternative to Endo-gas generators for many applications like carburizing, carbonitriding, annealing and hardening. Here Nitrogen gas is used as a carrier gas which reduces consumption of methanol. Cracking process at temperatures above 750˚C is as under:

CH3OH=2H2 + CO

n2methanolpic

Mixture of Nitrogen and Methanol (e.g. methanol 5 liters & Nitrogen 10 NM3) fed into furnace provides gas composition equivalent to Endo-gas as under:

Carbon Dioxide (CO2)
:  0.5% (Max)
Carbon Monoxide (CO)
:  20%
Hydrogen (H2)
:  40%
Nitrogen (N2)
:  Balance
Dew Point
:  (-) 40°C

Nitrogen gas of 99.5% purity from cylinders or from a captive PSA-Nitrogen generator is used. Methanol should be free from moisture for getting low dew point in your furnace.

Turn Key Supply
We supply "Nitrogen + Methanol" system on turn-key basis. For nitrogen gas generation, we supply a PSA Nitrogen generator and for methanol feeding we provide a methanol feed tank, methanol flow meter and a methanol inline vaporizer.

Applications
This type of generator is widely used in Heat Treatment furnaces for:
  • Carburizing
  • Carbo-nitriding
  • Annealing
  • Hardening
