Air Products has brought a large-scale, on-site ammonia (NH3) plant on-stream in China’s Anhui Province to supply ultra-high-purity NH3 to Anhui Sanan OptoElectronics Co. Ltd, a subsidiary of Sanan OptoElectronics (Sanan).
The plant, located at Sanan’s new high brightness LED (light emitting diode) manufacturing facility in the Wuhu Economic and Technological Development Area, is the largest on-site high-purity NH3 facility in the world with a supply capacity of 2000 metrics tons (2200 short tons) per year.
Sanan is the largest high quality LED manufacturer in China. Air Products is also building a second high-purity NH3 plant with the same capacity, due onstream mid-2012.
Large volumes of NH3 are needed to provide the nitrogen source for the gallium nitride layers used in LED manufacture.
“By working closely together, we successfully brought the world’s first and largest on-site facility onstream. It is a milestone for both Sanan and Air Products,” said Steve Jones, Air Products’ China president and senior vice-president and general manager of Global Tonnage Gases.
