Praxair, Inc., a wholly-owned subsidiary of Linde plc, has reached an agreement with Phillips 66 to supply high-purity hydrogen (H2) to the company’s Sweeny Refinery located in Old Ocean, Texas, starting in early 2021.

Praxair will extend its 310-mile US Gulf Coast H2 pipeline system, which currently runs from Freeport, Texas to Lake Charles, Louisiana, to connect with the Sweeny Refinery.

The Tier One corporation will also build, own and operate a new world-scale steam methane reformer (SMR) that will connect to the pipeline system at a location still to be determined.

The new SMR will supply Phillip’s Sweeny Refinery, as well as meet the H2 demands of new customers.

Upon expected completion in early 2021, this will be the largest H2 production unit in the US. The unit, which will have a state-of-the-art process design, will increase Praxair’s Gulf Coast H2 capacity to more than 1.5 billion cubic feet per day.

Dan Yankowski, President, Global Hydrogen and Carbon Monoxide, Praxair, said, “We are proud that world-class refiner Phillips 66 has chosen Praxair to be their H2 supplier at Sweeny. We are committed to providing our customers with supply reliability over the long-term.”

“Praxair understands that H2 is a critical requirement for our customers, and our robust H2 supply system, backed by multiple supply sources and an innovative high-purity H2 storage cavern, gives us a unique capability to meet that need.”

“Praxair is an existing supplier for many of our refineries,” said Bob Herman, Executive Vice-President, Refining at Phillips 66. “Praxair’s ability to develop a reliable and cost-effective supply solution at Sweeny Refinery contributed to our recent decision on H2 supply.”

With this new Phillips 66 agreement, Praxair is now uniquely positioned to supply H2 to the refineries located on the upper-Texas Gulf Coast.
