Praxair recently announced that it has started up a world-scale ASU at its Burns Harbor, Indiana, site.

The 2,400-ton-per-day ASU is part of Praxair’s ongoing investment in the company’s northwest Indiana operations. It will help further improve efficiency and continue to provide the reliable supply of pipeline oxygen and nitrogen required by refining and steel customers in the region.

“Over half of the operating iron blast furnaces in the United States are located in northwest Indiana and supplied from Praxair’s 130-mile pipeline system. This investment further strengthens Praxair’s supply reliability in the region, enabling us to help our customers grow and be more efficient,” said Joe Abdoo, north region vice president of Praxair’s U.S. industrial gases business.
