UOP: Propylene and isobutane production technology for Yantai Wanhua Polyurethanes  

By Gerald Ondrey |

UOP LLC (Des Plaines, Ill: www.uop.com), a Honeywell company, has been selected by Yantai Wanhua Polyurethanes Co. to provide technology to produce key petrochemicals to meet growing demand in China. Yantai Wanhua will use UOP’s process technology, catalysts and adsorbents to produce propylene, a building block for films and packaging, and isobutane, a raw material used in the polyurethane production process, at its facility in Yantai, China. The facility will use UOP C3 Oleflex process technology to produce 750,000 metric tons (m.t.) of propylene from propane annually and the UOP Butamer process to produce 565,000 m.t./yr of isobutane. In addition to technology licensing, catalysts and adsorbents, Honeywell’s UOP will provide engineering design, equipment, staff training and technical service for the project. The new units are expected to start up in 2013. The Oleflex process uses catalytic dehydrogenation to convert propane to propylene. Compared with alternative propane dehydrogenation processes, Oleflex technology provides the lowest cash cost of production and the highest return on investment. These outcomes are enabled by low operating and capital costs, high propylene yield and reliability, and maximum operating…
