Hydrogen by alkane steam-reforming

I. Technical Principle 

Raw material hydrocarbon gas is compressed (gas pressure for raw material is lower than 1.6Mpa), mixed with water vapor after refining desulfurization, and transformed and reacted by overheating under the action of catalyst into a fluidizing gas whose hydrogen content is larger than 70% (v/v%). The reforming gas is separated and purified by PSA unit to obtain product hydrogen.

II. Technical indicators 

Hydrogen pressure: 1.6~3.0Mpa

Hydrogen purity: 99~99.999%

Scale: 500~100000Nm3/h

Consumption: 0.4~0.42Nm3/Nm3 H2 (Converted to natural gas)

III. Characteristics and Advantages 

1. Low demands for public works, low energy consumption of hydrogen, low consumption, the lowest cost of hydrogen, and more suitable for large-scale hydrogen production.

2. High degree of automation, high safety performance.

3. Compared with coal gas: Small footprint, no pollution, no residue, good environmental performance.

IV. Application Fields 

Catalytic dry gas, coking dry gas, natural gas (LNG), naphtha, liquefied petroleum gas (LPG), refinery dry gas and other light hydrocarbon-rich ingredients
