Air Products Brasil's Bundled Offering a Winner for Long-Term Industrial Gas
Supply for Guardian Glass' New Float Glass Line

Cleanfire(R) HRi(TM) Burner Integrated in Expanded Glass Production

LEHIGH VALLEY, Pa., May 19 /PRNewswire-FirstCall/ -- Air Products (NYSE: APD)
today announced that its wholly-owned subsidiary, Air Products Brasil, has
built, placed on stream, and is operating an air separation plant that
provides nitrogen and oxygen for Guardian Industries' new float glass
manufacturing plant in Tatui, Sao Paulo, Brazil. Air Products Brasil is also
supplying hydrogen, via an on-site plant, and a Cleanfire(R) HRi(TM) burner
system for Guardian's new float glass line.

"We were able to demonstrate that significant operational benefits,
specifically fuel savings, can be achieved with the grouped offering we
presented to Guardian. The combination of our technologies and reliable
supply of essential industrial gases can provide Guardian with the most
efficient way, both operationally and environmentally, to produce float glass
from its new production line. These technologies can continue to provide
benefits in the future, as higher fuel and energy costs are anticipated," said
Bob Lewis, global marketing manager for Generated Gases at Air Products.
Lewis added that the Guardian relationship continues to grow Air Products'
presence and investment in meeting industrial gas needs in Brazil.

Air Products Brasil's construction of an air separation unit to produce
nitrogen and oxygen is part of the bundled product offering for Guardian
Tatui. Air Products Brasil is also operating an on-site steam methane
reformer (SMR) to produce hydrogen for Guardian's facility. Air Products'
on-site hydrogen product offerings were enhanced in 2008 by the acquisition of
Harvest Energy Technology and its novel and patented SMR technology. Further,
Air Products' Cleanfire HRi burner advanced oxy-fuel boost application has
been integrated into Guardian's new glass production plant.

Float glass is produced by floating a continuous stream of molten glass onto a
bath of molten tin. The molten glass spreads onto the surface of the metal
and produces a high quality, consistently level sheet of glass that is later
heat polished. The glass has no wave or distortion and is now the standard
method for glass production. In fact, over 90% of the world production of
flat glass is float glass. Float glass can be cut and fitted directly to
frames or custom tabletops for making modern windows, or used as raw material
in processes such as glass tempering, lamination, and manufacture of mirrors
and solar panels.

When introduced correctly, industrial grade oxygen used to displace combustion
air in the manufacturing process can significantly improve heat transfer to
the glass batch and glass bath. The Cleanfire HRi burner's advanced oxy-fuel
boost application offers several unique benefits to glass production. "This
technology delivers higher efficiency melting that reduces the amount of fuel
consumed to produce each ton of glass. It also reduces the amount of
pollutant emissions by delivering a flat flame geometry that incorporates
oxygen staging technology," says Kevin Lievre, global glass segment market
manager at Air Products. "Customers using this Cleanfire application can
expect to increase glass quality, boost production, and decrease emissions of
NOx, SOx, CO2, and particulate matter."

Currently there are over 250 Cleanfire HRi burners installed at glassmakers
worldwide, and over 1,500 of the Cleanfire family of burner offerings in place
at glassmaking operations globally.
