Large Scale Coal Hydrogen Production 45000Nm3/H Mature Process

Large Scale Coal Hydrogen Production 45000Nm3/H Mature Process

Shougang 45000Nm³/H Coal Hydrogen Production

Technology Application:

Techairs is a domestic company with the most outstanding performance in intermittent production of hydrogen from coal (with wide source of raw material, such as powdered coal, lump coal, anthracite, lignite, industrial coke oven gas and crude gas etc.), and the technology has reached the world advanced level. The coal to gas PSA is successfully adopted for the hydrogen production as well as the crude gas PSA and the coke oven gas purified PSA.

Raw coal (coal, anthracite and lignite), steam and oxygen (oxygen or air) chemical reaction in the gas furnaceand and generating water gas, Water gas by washing purification, electrostatic precipitation, atmospheric desulfurization, compression, transformation, fine desulfurization, and finally through the PSA hydrogen extraction, can be qualified hydrogen products. The hydrogen production method is suitable for the users with need large amount of hydrogen and convenient storage and transportation coals. Chemical reaction is as follows:

C + H2O → CO + H2 -Q

C + 2H2O → CO2 + 2H2 -Q

CO + H2O → CO2 + H2 + Q

Technical indexes:

Purity: 99%~99.9999%

Capacity: ≥2000Nm³/h

Yield :≥80%

Features and advantages:

Mature process technology and safe and reliable operation.

Wide source of raw material and large processing scale.

Four stages of full low conversion process with the CO conversion rate >95%.

Advanced recovery technology of thermal energy and low consumption of production energy.

The "three wastes" boiler is adopted, being environmentally friendly.
