Hazards and safety
Extremely flammable. Burns with an almost invisible flame. A sample asphyxiant. Liquid hydrogen and cold gaseous hydrogen can cause freeze burns.
Applications
- Oxygen assisted steel melting, post combustion processes, re-heating furnaces and DRI in HADEED.
- Oxygen enrichment in the glass and ceramic industry.
- Catalytic oxidation processes.
- Ethylene oxide for production of ethylene glycol.
- Acetic acid, e.g. SABIC Acetic Acid Plant and Mega Methanol.
- Recovery of hydrocarbons in purge streams using oxygen.
- Enter in oxidation reaction in claus process to recover sulfur.
- In hospitals oxygen is piped from the central tank to the operating room & intensive care unit.
Storage and handling
Use no oil or grease. Open valve slowly to avoid pressure shock. Segregate from flammable gases and other flammable materials in store. Suck back of water into the container must be prevented. Do not allow backfeed into the container. Use specified equipment which is suitable for this product, its supply pressure and temperature. Contact your gas supplier if in doubt.
Packaging
Gaseous oxygen is supplied through pipeline grids which extend to the port. Liquid Oxygen is supplied through tankers.
