Praxair has started up three new vacuum pressure swing adsorption (VPSA) plants at the Daesan petrochemical complex located on the west coast of the Korean peninsula.

Under a long-term contract, the VPSA plants will supply a combined 750 tonnes per day of oxygen to Hyundai Oilbank, one of the leading refinery companies in Asia with a capacity of 520,000 barrels per day of crude oil and other feedstock. Hyundai has produced gasoline and propylene in South Korea for more than 50 years. The oxygen is being used in their Residue Fluid Catalytic Cracking (RFCC) process.

Praxair was the first to develop VPSA technology and is the leader in VPSA applications for oxygen production. With more than 250 VPSA plants globally, over the last 25 years the company has built a strong track record of supply reliability and technical expertise.

BS Sung, President of Praxair Korea said, “Praxair’s long-term expertise building and operating these plants has been rewarded by Hyundai, the leading refinery company in the Daesan petrochemical complex.”

He continued, “These VPSA plants further strengthen our presence in the region and will help drive future growth.”

Praxair will start up a fourth VPSA plant in early 2018.
