BOC Begins Supplying Hydrogen To Chevron And Holly Oil Refineries

Murray Hill, NJ - BOC, a U.S. affiliate of The Linde Group, has begun supplying hydrogen for cleaner fuel production from its newest hydrogen plant in Salt Lake City, Utah.

BOC is a division of The BOC Group, Inc., which Linde AG acquired in 2006 to form The Linde Group, one of the leading engineering and industrial gases companies.

The plant, which is capable of producing some 26 million standard cubic feet a day of hydrogen, began supplying Chevron and Holly Corporation's Utah subsidiary earlier this year with hydrogen for use in new oil refining production units. The refiners added the new processing units to meet or exceed the U.S. Environmental Protection Agency's lower-sulfur requirements for gasoline and diesel fuels.

Chevron, which installed additional hydrotreating capacity at its 49,000 barrel-a-day refinery, is taking hydrogen and steam from BOC's plant, located within the Chevron refinery. BOC will deliver hydrogen to Holly through a five-mile pipeline connection to a new hydrotreating facility at Holly's 26,000 barrel-a-day Woods Cross refinery.

This plant – the only third-party hydrogen plant serving Salt Lake City-area refineries – is part of BOC's ongoing effort to add hydrogen capacity where it's most needed. BOC recently boosted hydrogen production by some 175 million standard cubic feet a day with additional plants in Toledo and Lima, Ohio.

"We are pleased to support Chevron and Holly in their efforts to meet consumers' energy needs. When so much of the world's attention is focused on ensuring secure energy sources and reducing greenhouse gas emissions, BOC is proud to provide cost-effective solutions to refining customers while also protecting the environment," said Ray Carr, vice president, tonnage, for Linde in North America.

Pat Murphy, North America regional business unit head for Linde, said, "Around the world, BOC and Linde have decades of expertise in designing and safely delivering hydrogen supply schemes tailored to meet customers' unique needs. Our plants' reliability, which is critical to this business, is among the highest and continually rising. We also have the highest commitment to ensuring the safety of our employees, customers and neighbors."

With more than 47,000 employees, Chevron subsidiaries conduct business in approximately 180 countries around the world, producing and transporting crude oil and natural gas, and refining, marketing and distributing fuels and other energy products.
