China installs its largest nitrogen generator

13th March 2012

The latest 8.5 generation TFT-LCD manufacturing facility has been launched in the Beijing Development Authority as part a drive by the Chinese government to boost its domestic TFT-LCD industry.

Linde LienHwa (LLH), the Linde Group’s joint venture with LienHwa MiTAC Group of Taiwan, has opened an ultra-high purity gas plant at BOE Technology Group. 

“This new plant strengthens our position as a leading gas supplier for the electronics industry in China, and demonstrates the increasing demand for our gases from electronics manufacturers looking for the most technologically advanced, cost effective and environmentally sustainable solutions,” said Andrew Lau, general manager of Linde LienHwa in China.

Large volumes of ultra-high purity gases play a critical part in the manufacture of TFT-LCD technologies, according to Linde LienHwa. They are used to create the microscopic thin-film transistors required to control each of the thousands of pixels that make up the visible image. 

The new facility developed by LLH consists of an installation of the plant’s bulk gases supply systems, including on-site nitrogen plants including one SPECTRA-N 30,000 series ultra-high purity nitrogen generator, the biggest of its type in China. This allows the supply of 30,000Nm3/hour of nitrogen via an underground pipeline. LLH has also constructed high capacity liquid nitrogen storage tanks and storage and supply systems for other gases on the site, including oxygen, hydrogen and argon.
