Airox Nigen offers Hydrogen Plants based on Methanol Cracking. We provide high Hydrogen Gas better than 99.999%, to meet a variety of our client’s industries and advance technology application. Methanol Cracking is an extremely useful technology being used to generate Hydrogen at low cost. The plant offers a short Payback period and is built with high safety features and automation. Methanol is considered as a preferred raw material in view of its easy availability and storage features.
Beside endothermic gas or endo gas, more and more methanol is used for the thermal treatment of metals as a protective gas. The methanol is directly inserted into the furnace and cracked there.
CH3OH → CO + 2 H2
Carbon monoxide and hydrogen are formed. The methanol cracking gas is an excellent carrier gas. Hydrogen and carbon monoxide are reducing agents and avoid oxidation or corrosion of metal surfaces in a furnace. It must be taken into account however, that carbon monoxide increases the carbon content of steel. Methanol cracking gas can therefore be used for surface hardening of steel by carbonisation or carburization. Carbon concentration can be increased up to the saturation level of austenite in surface close areas (around 1mm deep). In order to control the carbonization, water vapour can be added, or nitrogen can be used for dilution.
