Air Liquide Engineering and Construction will supply a hydrogen (H2) purification pressure swing adsorption (PSA) unit to one of the worlds largest methanol production facilities to be built by Yuhuang Chemical Inc (YCI) in St. James Parish, Louisiana, as per recently signed agreement.

The PSA is part of a full suite of H2 technologies that Air Liquide Engineering and Construction offers to its customers. The company has more than 70 PSA references and combines state-of-the-art technology with a wide range of the best performing adsorbents on the market.

The customers also benefit from operating experience gained from a large fleet of PSA units owned and operated by Air Liquide, and from the unique combination of a methanol technology licensor and a PSA supplier for the specific application of H2 recovery in methanol plants.

YCI is a loyal customer of Air Liquide. In 2014 Air Liquide was selected as the technology provider for the methanol plant and in 2015 as the supplier of oxygen (O2) for its world scale methanol manufacturing complex. Air Liquide Engineering and Construction also provides detailed engineering and procurement services for the complex.

Construction of the methanol complex began this year, with the first phase of the methanol project due to start operation in late 2019.

Chad Briggs, Vice-President Sales & Technology of Air Liquide Engineering and Construction, said, “Air Liquide Engineering & Construction is pleased to provide H2 purification solutions complementing our methanol and ASU technologies for the largest methanol production facility in Louisiana. Our capabilities in designing and operating PSA units date back to the early 1960s and since then we continuously improve our offer for the benefit of our customers. This is the case with YCI, who has proven to be a valued partner and we look forward to a long lasting relationship.’’
