Air Products brings onstream first on-site high-purity ammonia plant in China to support booming LED market

Air Products of Lehigh Valley, PA, USA has brought onstream a large-scale, on-site ammonia (NH3) plant 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, at Sanan’s new high-brightness LED manufacturing facility in the Wuhu Economic and Technological Development Area, is claimed to be the largest on-site high-purity NH3 facility in the world, with a supply capacity of 2000 metrics tons per year.

Sanan is the largest high-quality LED maker in China. To support its expansion plan, Air Products is also building a second high-purity NH3 plant with the same capacity, which is expected to come onstream in mid-2012. Large volumes of NH3 are needed to provide the nitrogen source for the gallium nitride layers in LED manufacturing.

On 12 December a grand opening ceremony was held at Sanan’s Wuhu facility to celebrate the milestone. Attendees included Steve Jones, Air Products’ China president and senior VP & general manager of Global Tonnage Gases, Energy and Equipment; Joseph Stockunas, director of electronics materials for Air Products; plus representatives from Sanan.

“Air Products has a long and proven record of building large-scale, on-site industrial gas plants around the world,” says Jones. “We are pleased Sanan OptoElectronics chose Air Products for their high-purity ammonia supply to support its increased LED production. By working closely together, we successfully brought the world’s first and largest on-site facility onstream,” he adds.
