Praxair, Inc. has started up two new air separation plants to supply China National Offshore Oil Corporation (CNOOC), a Fortune Global 100 company and one of the largest in China. 

The two plants, each with 2,400-tonnes-per-day of oxygen (O2) capacity, are supplying on-site Oand nitrogen (N2) to CNOOC to support the company’s refinery expansion and related downstream chemical production.

With the start-up of the two new plants, Praxair is now operating a 5,600-tonne-per-day production complex, made up of four air separation units (ASUs). These units are serving a total of nine customers in the Huizhou Daya Bay Chemical Industrial Park, located in Huizhou, Guangdong, China, including the CNOOC and Shell petrochemical complex.

“This project not only expands our relationship with CNOOC, but also enables us to build density and increase supply reliability to all of our valued customers in the park and throughout southern China,” said Will Li, President of Praxair China. 

Li continued, “Praxair is driving further profitable growth through disciplined investment in select projects such as this one, and we look forward to building on our momentum in the region.”
