Praxair, Inc. has signed a long-term agreement with Delaware City Refining Company in which Praxair will purchase crude carbon dioxide from the refinery.

Praxair will build, own and operate a 450-ton-per-day carbon dioxide purification and liquefaction plant at the refinery, producing beverage-quality liquid carbon dioxide for distribution into the Northeastern U.S. merchant market. Praxair already supplies Delaware City Refining with nitrogen for its operational needs.

This new carbon dioxide source, which will begin serving customers in 2016, further strengthens Praxair’s supply position in the Northeast. Praxair previously started up a 450-ton-per-day carbon dioxide purification facility in Hopewell, Virginia, and also operates carbon dioxide facilities in Southeastern Canada.

“Our growing network of carbon dioxide recovery plants and depots makes Praxair the premiere source of purified carbon dioxide in the Northeast,” said Jeff Barnhard, vice president, east region for Praxair’s U.S. industrial gases business.

“We are pleased to be expanding our relationship with Delaware City Refining and look forward to continuing to serve food and beverage and other carbon dioxide customers in the future. Sustainability is important to Praxair as well as to our suppliers and customers. By recovering this resource, we are able to meet our customers’ needs while making beneficial use of carbon dioxide from Delaware City Refining.”

Delaware City Refinery Manager José Dominguez said, “We look forward to working with Praxair on this important project, which in turn will support other businesses in the region.”
