Why is the Ozone layer disappearing well Ozone is three oxygen atoms joined together and what we have is a lack of oxygen to form three atom molecules. Oxygen joins easily with any other element and here is the real problem and when this happens it takes atoms of Oxygen from the ozone layer. That's it simple....
Production of OxygenOxygen, the second-largest volume industrial gas, is produced commercially as a gas or as a liquid by several methods. These include:
|» ||Cryogenic Air separation, a process that compresses and cools atmospheric air, then, - relying on different boiling points - separates the resulting liquid into its components in a distillation column|
|» ||Vacuum Pressure Swing Adsorption (VPSA), a non-cryogenic technology that produces oxygen from air by using an adsorbent in a pressure swing process to remove nitrogen|
