N2 Methanol

TECHNICAL FACTS

FLOW RANGE

Flow rates of these generators ranges from 5 to 100 nm3/hr.

PURITY

99.5% purity Nitrogen is standard. Higher purities are available on request.

DEW POINT

Standard dew point offered is (-)40?C. Lower dew points are available on request.

HOW IT WORKS?

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:

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:

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.
