Hydrogen

Purity : 99.7%

Capacity : 7.00 Cu. M

Hydrogen (H2) is a colorless, odorless, tasteless, flammable and nontoxic gas at atmospheric temperatures and pressures. It is the most abundant element in the universe, but is almost absent from the atmosphere as individual molecules in the upper atmosphere can gain high velocities during collisions with heavier molecules, and become ejected from the atmosphere. It is still quite abundant on Earth, but as part of compounds such as water.

Hydrogen burns in air with a pale blue, almost invisible flame. Hydrogen is the lightest of all gases, approximately one-fifteenth as heavy as air. Hydrogen ignites easily and forms, together with oxygen or air, an explosive gas (oxy-hydrogen).

Hydrogen has the highest combustion energy release per unit of weight of any commonly occurring material. This property makes it the fuel of choice for upper stages of multi-stage rockets.

Hydrogen has the lowest boiling point of any element except helium. When cooled to its boiling point, -252.76o C (-422.93o F) hydrogen becomes a transparent, odorless liquid that is only one-fourteenth as heavy as water. Liquid hydrogen is not corrosive or particularly reactive. When converted from liquid to gas, hydrogen expands approximately 840 times. Its low boiling point and low density result in liquid hydrogen spills dispersing rapidly.

Product Description

Metals:
Hydrogen is mixed with inert gases to obtain a reducing atmosphere, which is required for many applications in the metallurgical industry, such as heat treating steel and welding. It is often used in annealing stainless steel alloys, magnetic steel alloys, sintering and copper brazing.

Hydrogen can be produced by dissociation of ammonia at about 1800˚F with the aid of a catalyst – which results in a mix of 75% hydrogen and 25% mononuclear nitrogen (N rather than N2). The mix is used as a protective atmosphere for applications such as brazing or bright annealing.

Chemicals, Pharmaceuticals and Petroleum:

Hydrogen is used in large quantities as a raw material in the chemical synthesis of ammonia, methanol, hydrogen peroxide, polymers, and solvents.

In refineries, it is used to remove the sulfur that contained in crude oil. Hydrogen is catalytically combined with various intermediate processing streams and is used, in conjunction with catalytic cracking operations, to convert heavy and unsaturated compounds to lighter and more stable compounds.

The pharmaceutical industry uses hydrogen to manufacture vitamins and other pharmaceutical products.

Large quantities of hydrogen are used to purify gases (e.g. argon) that contain trace amounts of oxygen, using catalytic combination of the oxygen and hydrogen followed by removal of the resulting water.

Glass and Ceramics:

In float glass manufacturing, hydrogen is required to prevent oxidation of the large tin bath.

Food and Beverages:

It is used to hydrogenate unsaturated fatty acids in animal and vegetable oils, producing solid fats for margarine and other food products.

Electronics:

Hydrogen is used as a carrier gas for such active trace elements as arsine and phospine, in the manufacture of semi-conducting layers in integrated circuits.

Miscellaneous:

Generators in large power plants are often cooled with hydrogen, since the gas processes high thermal conductivity and offers low friction resistance.

Liquid hydrogen is used as a rocket fuel.

The nuclear fuel industry uses hydrogen as a protective atmosphere in the fabrication of fuel rods.
