Can nitrogen reduce costs and improve operations in my dissociated ammonia (DA) atmosphere?

John Kaiser
Applications Engineer

Nitrogen-DA dilution can be a cost-effective alternative to 100% DA. Since many materials being processed do not require the 75 percent hydrogen content in DA, you can reduce your atmosphere cost by using less costly nitrogen to dilute your DA. The use of nitrogen also provides an economical means for purging in addition to a lower cost for furnace idling. Also, using hauled-in hydrogen with nitrogen to replace DA can be cost-competitive and completely eliminate ammonia—a more toxic, more expensive gas.

Air Products applications engineers can help you compare atmosphere costs and
recommend ways to reduce atmosphere consumption to further reduce your total cost of
ownership. To find out more, contact us online or give us a call at
