Praxair has been awarded a hydrogen contract by Shell Oil Company to supply high-purity pipeline hydrogen to Shell’s Deer Park, Texas, refinery for the production of ultra-low sulfur motor fuels.

Praxair will supply hydrogen to Shell’s refinery from a system of steam methane reformers and hydrogen recovery units.

The units will be connected via a 300-mile hydrogen pipeline network along the U.S. Gulf Coast, beginning in 2010.

This system is also strategically integrated with Praxair’s unique hydrogen storage cavern, to provide high levels of supply flexibility and availability.

“We are very pleased to have been selected by a global leader in the refining industry to supply hydrogen to one of Shell’s most important refineries,” said Anne Roby, Vice President of the south region for Praxair’s North American Industrial Gases business.

“Praxair understands the complex and changing needs of refiners, especially in today’s environment, and is committed to being the supplier of choice,” she added.

The 340,000-barrels-per-day Shell-operated refinery at Deer Park is the sixth largest in the United States.

It is a 50-50 joint venture partnership between Shell Oil Company and PMI North America S.A. de C.V., a wholly-owned subsidiary of Petróleos Mexicanos (Pemex).

Since the partnership was formed in 1993, significant investments have been made to upgrade the refinery to handle heavy sour crude, and produce transportation fuels that meet the most stringent low-sulfur specifications.

Praxair has been providing Shell’s Deer Park refinery and chemical complex with oxygen and nitrogen for over 40 years, as well as large volumes of industrial gases and services to 11 additional Shell facilities in four countries.
