Product Applications
1. High-purity hydrogen finds widespread usage in the electronics industry as a reducing agent and as a carrier gas.
2. 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.
3. 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.
4. In industry, it is used to supply oxygen-hydrogen torches for glass working (quartz, Pyrex®, etc), in the fabrication of artificial precious stones (ruby, etc), and for under water oxycutting
5. In the laboratory, it is used in analyzer flames, reducing flame photometry detection instruments,flame ionisation detection instruments, and fuel cells.
