PSA nitrgen plant gas recovery

plasma cutting comes to mind of speciality metals.

Hospitals need Liquid oxygen. You can try to store the excessive oxygen in liquid form and sell it either through pipe net works or tanker all as per HTM standards.

Depends on what your plant does. I used to work in lead furnaces, where adding oxygen to the blast air increased the efficiency of the furnace. The reduction in nitrogen blown through the furnace reduced the load on the fans and reduced the amount of fuel needed. At a pulp mill where I also worked, oxygen is used to bleach the pulp. This reduces the need for chlorine. More envoirmently friendly.Oxygen could be fed in with the combustion air to a boiler to improve efficiency, BUT there would have to be safeguards installed to stop oxygen flow, if the fire is lost.

Good reply and You are very much right Mr. vtbgiraud, I tried to use it for boiler in ID fan suction but withdraw scheme due to red heating problem of furnace.

Ours is a chemical industry, unfortunately with no use of oxygen any in the process. Using it boiler seems to be good idea. how safe is it?or anyother methods of using it?
