PSA Nitrogen + Methanol

Use of furnace atmospheres based on Methanol cracing has become widely acceptable as alternative to Endo-gas generators for many applications like carburizing, carbonitriding, annealing and hardening. However, dissociated methanol must be used with Nitrogen gas from the point of view of safety. Here Nitrogen gas is used as a carrier gas which reduces consumption of methanol. Cracking process at temperatures above 750^oC is as under:
CH₃OH=2H₂ + CO

Mixiture of Nitrogen and Methanol (e.g. methanol 5 liters & nitrogen 10 Nm³) fed into furnace provides gas composition equivalent to Endo-gas as under:

CO₂	0.5% (max)
CO	20%
H₂	40%
N₂	Balance
Dew point :	(-) 40^oC

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

Turn - Key Supply

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