Acetylene - Products - Irish Oxygen Company Ltd

Acetylene is also produced in chemical plants but normally the gas produced in such plants is used as feedstock in the same plant for further chemical synthesis. The remaining 20% is used primarily for oxy-acetylene gas welding and cutting due to the high temperature of the flame. Combustion of acetylene with oxygen produces a flame of over 3300 °C -- Oxy-acetylene is the hottest burning fuel gas.


Argon - Products - Irish Oxygen Company Ltd

It is used to provide a shielding atmosphere in welding, metal fabrication, aluminium processing, micro-electronics, glass coating, and other industrial processes. In the air extraction process, crude liquid argon is formed in the distillation column of an air separation unit. Argon, symbol Ar, is an inert gaseous element that is the third most prevalent gas in the earth's atmosphere.


Carbon Dioxide - Products - Irish Oxygen Company Ltd

Carbon dioxide is recovered from the fermentation processes and as a by-product in the commercial production of ammonia. Carbon dioxide's inert qualities make it useful for preventing or suppressing combustion or oxidisation. It is often used to balance the pH of water in preference to the addition of mineral acids. The gas dissolves easily in water, making the resultant solution slightly acidic.
