DANBURY, Conn.--(BUSINESS WIRE)--Oct. 24, 1995--Praxair, Inc. (NYSE: PX) announced today that it has completed construction of a new, patented on-site ultrahigh purity (UHP) nitrogen generation plant at NEC Electronics, Inc.'s (NECEL) semiconductor manufacturing facility in Roseville, California.

Praxair currently has commitments totaling over $85 million to build five more on-site nitrogen plants (N-plants) that use this new technology, which features plant sizes from 10,000 standard cubic feet per hour (scfh) to over 300,000scfh and an optional UHP oxygen production capability. The new plant meets NECEL's requirements to upgrade nitrogen purity, expand plant capacity, without increasing energy consumption. With the new, upgraded N-plant from Praxair, NECEL will be able to generate 80 percent more nitrogen at no additional energy cost.

"It's win-win for our customers, who receive higher purity product, gain production efficiencies, and add capacity without additional site investments. With its innovative design, this process also brings as much value and reliability to customers requiring new nitrogen production facilities as it does for customers looking for upgrades," says David Thompson, product manager, bulk gases and nitrogen plants.

The new plant at NECEL has the capacity to supply 180,000 scfh of nitrogen, at a purity level of less than 1 part per billion. Praxair currently supplies NECEL with nitrogen, oxygen, hydrogen, argon, specialty process gases, along with comprehensive site gas services.

Praxair is the largest supplier of on-site nitrogen plants in North America, and has supplied over 30 electronics customers with on-site high purity nitrogen for over 30 years, and over 170 customers in steel, glass, food, chemical an other industries.

NEC Electronics, Inc. is a wholly-owned subsidiary of NEC Corporation, Tokyo, producing a wide range of metal oxide semiconductor (MOS) dynamic memories, microprocessors and application specific integrated circuits (ASICs).

Praxair is the largest industrial gases company in North and South America, and one of the largest worldwide, with 1994 sales of $2.7 billion. The company produces, sells and distributes atmospheric, process and specialty gases, and high-performance surface coatings. Praxair is a leader in the commercialization of new technologies that bring productivity and environmental benefits to a diverse group of industries.
