Praxair Korea, a wholly-owned subsidiary of Praxair Inc., has started up a new air separation unit (ASU) at Samsung’s Tangjeong complex in Tangjeong, Korea.

The new ASU will supply 1,975 tpd of nitrogen gas to support Samsung Electronics' advanced thin-film-transistor, liquid-crystal-display (TFT-LCD) factory in Tangjeong.

It is Praxair’s second air separation plant at the facility.

Samsung’s Tangjeong complex is the world’s first and largest eighth generation TFT-LCD plant and is designed to expand to meet demand for future generations of LCDs.

“Praxair Korea has worked successfully with Samsung for more than 17 years, increasing supplies of gases for the company’s main manufacturing complexes in Giheung, Hwasung and Tangjeong,” said S.B. Seo, President of Praxair Korea.
