Praxair begins operations at new hydrogen facility for Dow’s Freeport, US


US-based industrial gas supplier Praxair has started-up its new hydrogen plant, which will recover by-product streams from Dow Chemical Company’s operations in Freeport, Texas.

The newly opened plant will also process, recover and compress by-product hydrogen from Dow’s ethylene production facilities, which includes the company’s new ethylene cracker scheduled to become operational this year.

Processing hydrogen at Praxair’s new plant will further enable Dow to meet the industry demands of reducing carbon dioxide emissions.

In addition, Praxair has entered a long-term contract to supply nitrogen for Dow’s chemical production facility. Praxair will also provide high-purity hydrogen Dow’s south-east Texas operations.

"Capturing by-product hydrogen for use in the refining and petrochemical industries is consistent with our mission of making our planet more productive."

Dow will use both hydrogen and nitrogen, which will be delivered by Praxair from 2019, to support production of various specialty chemicals used in several end-markets, such as automobile manufacturing, coating applications and chemical intermediates.

Praxair global hydrogen business president Dan Yankowski said: “Freeport is Dow’s largest chemical site in the world and we are proud to be supporting their continued growth in the US Gulf Coast.

“This opportunity to further serve our customers in the region is why we extended our pipeline to Freeport.

“Capturing by-product hydrogen for use in the refining and petrochemical industries is consistent with our mission of making our planet more productive.”

The company said that its pipeline system is supported by a number of hydrogen plants, as well as its 2.5 billion standard cubic foot storage cavern, which uses patented technology.
