The US Department of Energy has approved the Cameron LNG facility for LNG export up to 12 million tons every year.
Air Products’ sale includes three main cryogenic coil wound heat exchangers and the associated equipment and technology.
Air Products LNG director Jim Solomon said: "The export market for LNG in the United States (U.S.) is new and developing, and we have been successful in winning the business for several of the most recently announced projects.
"We are pleased to support Cameron LNG at the Louisiana location, and after decades of our technology operating at many locations around the world, we look forward to seeing our technology operating here in the U.S."
Cameron LNG CEO Farhad Ahrabi said: "Cameron LNG, as one of the first new liquefied gas export terminals in North America, is currently under construction.
"Air Products is an essential part of Cameron LNG’s efficient solution to delivering safe and reliable LNG to our customers."
Cameron LNG is jointly owned by Sempra, GDF SUEZ, Mitsui, and Japan LNG Investment (a company jointly owned by Mitsubishi Corporation and Nippon Yusen Kabashiki Kaisha).
Air Products will supply its LNG proprietary C3MRTM liquefaction technology and equipment, and its MCR Main Cryogenic Heat Exchangers, which will be installed at the heart of the propane pre-cooled mixed refrigerant liquefaction process.
