LEHIGH VALLEY, US: Air Products has licensed its proprietary adsorption-based monomer recovery technology to Cryo Technologies, a worldwide supplier of custom engineered process equipment based in Allentown, US. Air Products’ process for unreacted olefin recovery combines partial condensation with pressure swing adsorption to deliver two product streams - a recovered hydrocarbon product for recycle and subsequent polymer production, and a nitrogen stream for reuse in facility operations, such as polymer degassing and pneumatic transportation.
The technology license agreement enables Cryo Technologies to design and offer Air Products’ unreacted olefin recovery technology, which has been proven through the development, testing, and successful operation of three full-scale facilities that Air Products designed and supplied to polypropylene and polyethylene manufacturers in the US.
“Cryo Technologies is pleased to have the opportunity to offer the benefits of Air Products’ unreacted olefin recovery technology to the petrochemical industry. Our experience and comprehensive capabilities in custom-engineered and packaged process systems, combined with Air Products’ proprietary adsorption-based technology, will enable polyethylene and polypropylene production facilities to improve their economics and minimize emissions in their monomer recovery processes,” said Richard Hessinger, President, Cryo Technologies.
