Air Products and MATHESON Break Ground for New Wyoming Helium Plant


LEHIGH VALLEY, Pa., Oct. 12 - Air Products (NYSE: APD) and MATHESON, a member of the Taiyo Nippon Sanso Corporation (TNSC) group, today announced that on-site construction has commenced on a new, jointly-owned liquid helium production plant near Big Piney, Wyoming. The plant, designed to produce 200 million standard cubic feet per year at start-up, with expectations for future expansion to 400 million standard cubic feet per year, would process crude helium produced by a natural gas processing facility that would be operated by Cimarex Energy Co.

The Cimarex facility, which is currently under construction, will process natural gas from the Riley Ridge Field in Wyoming, one of the largest helium-rich natural gas fields in the United States. The Riley Ridge field is believed to contain sufficient helium reserves to support production for decades. Production at the new Wyoming plant is anticipated to commence in 2011.

Air Products, the global leader in helium production, has pioneered many of the helium extraction, production, distribution and storage technologies used in the industry today. Air Products maintains the world's largest helium production and distribution system and operates numerous facilities around the world.

"The Big Piney plant will further diversify our helium source portfolio and enhance our ability to reliably serve our customer base," said John Van Sloun, general manager - Worldwide Helium at Air Products. "We are excited to be involved with this project as a direct participant because it will enable us to provide high on stream operations and reliable supply." Van Sloun added, "Air Products continues to look for other helium source opportunities where we can participate both as an investor and an operator."

MATHESON manages the global helium business of TNSC under the name MATHESON Global Helium. TNSC is the leading helium supplier in Japan, and is one of only five major industrial gas companies in the world with direct access to helium sources.

"The helium produced from the Big Piney Plant will help to solidify MATHESON's helium supply for the long term and will give us the opportunity to grow our business. We are pleased that our newest source will be located in Wyoming, close to our existing supply from ExxonMobil, which will enable us to have a simple, efficient and reliable supply chain to serve our customers located in the U.S. and Asian markets," said Phil Kornbluth, executive vice president, International and Helium for MATHESON.

Upon completion, the Wyoming helium production plant will be the 10th liquid helium plant operating in the United States, and the first new U.S. facility constructed in over a decade. It is expected to employ 8-10 people after start-up.

Helium is used in many unique and valued applications including: magnetic resonance imaging (MRI); lifting for high altitude scientific research balloons, blimps and party balloons; fiber optics and semi-conductor manufacturing; metallurgy; breathing atmospheres for deep diving or unique blood gas medical mixtures; analytical chemistry; pressurizing and purging pipes, vessels, and other critical equipment; leak detection; and other advanced applications.
