Principle of Purification

The reaction of oxygen with hydrogen and nitrogen in the raw material is carried out under the action of catalyst.

The reaction chain of the purification is longer, and even relates to the high temperature vessel. The accuracy and stability of control for the whole process is very important.

Principle of Operation

After the raw material nitrogen is mixed with a small amount of hydrogen, the residual oxygen reacts with hydrogen to become water vapor in a reactor filled with catalyst:

2H₂ + O2 = 2H₂O + heat

Catalytic Hydrodeoxygenation:

2H₂＋O2H₂O＋Q

Dehydrogenation:

M＋mOa＋H₂M＋nOb ＋H₂O＋Q

Dehydrogenating Agent Regeneration:

M＋nOb ＋O2 M＋mOa＋Q

M…metal     Q…quantity of heat     m > n     a > b 

Then after-cooler  will make most of the water vapor condensation, to remove condensate by going through the high efficiency water separator. Adsorption dryer can make the  dew point of production gas below -60℃, the purity of production gas is continuously online monitored by the analyzer.
