hydrogen Source

Hydrogen is most frequently produced for on-site usage by steam reforming of natural gas. Such plants may also be used as sources of hydrogen for the merchant market. Other sources are the chlor-alkali process that electrolyses sodium chloride solution to produce chlorine, and various waste gas recovery plants, such as at oil refineries or steel plants (coke oven gas). Hydrogen is also produced by electrolysis of water.

 

Hydrogen Uses and Applications

High-purity hydrogen finds widespread usage in the electronics industry as a reducing agent and as a carrier

gas.

 

High-purity hydrogen is used as a carrier gas in gas chromatography.

 

Hydrogen finds some usage in the welding and cutting of metals.

 

Hydrogen is used in large quantities, (bulk supply or on- site generation) for the hydrogenation of vegetable and animal oils to produce margarine and other fats, hydro- treatment of petroleum products, and hydrosulfuration of fuels in order to eliminate sulfur.

 

Hydrogen in large quantities is used in petrochemical processes that include hydrodealkylation, hydrodesulfurisation, hydrotreatment.

 

Hydrogen is used in leak testing applications.

 

Hydrogen is used in HF/DF chemical lasers.

 

Hydrogen is used extensively in the metals industries because of its ability to reduce metal oxides and prevent

oxidation of metals during heat treatment. It may be used either pure, as is often the case when heat treating stainless steel, or in a mixture with inert gases, argon or nitrogen. It is used in the production of carbon steels, special metals and semiconductors.

 

 

Hydrogen is used for combustion;

• in industry, it is used to supply oxygen-hydrogen torches for glass working (quartz, Pyrex®, etc), in the
• in the laboratory, it is used in analyzer flames, reducing flame photometry detection instruments, flame

 

Extremely pure hydrogen is used in the chemical industry for fine reduction processes.

 

Liquefied hydrogen is used as a rocket fuel. In the laboratory liquid hydrogen is employed for solid physics

research.

 

In the nuclear industry para-hydrogen is employed to fill bubble chambers.

 

In electrical power plants hydrogen is used as a coolant gas in turbogenerators.

 

Hydrogen is used for synthesis of ammonia.

 

Hydrogen is used as a reagent to produce high-purity water.

 

Hydrogen is used as fuel in fuel cell applications.

 

Hydrogen is used as component in gas mixtures.
