China’s Longgang Chemical Co. has selected technology from a Honeywell company to produce key ingredients for fuels and synthetic rubber.

The UOP C4 Oleflex process from UOP LLC, Des Plaines, Ill., will be used to convert refinery-derived isobutane to isobutylene, a petrochemical used in the production of fuels and synthetic rubber. This is UOP’s second C4 Oleflex process license in China. In addition to technology licensing, Honeywell’s UOP will provide basic engineering, catalysts, adsorbents, specialty equipment and engineering for the project.

Longgang Chemical Co. will use Honeywell’s UOP technology to process 175,000 metric tons of mixed butane feedstock annually at its facility in Dongying City, Shandong Province, China. The facility is expected to start up in 2015.

The C4 Oleflex process uses catalytic dehydrogenation to convert isobutane to isobutylene. Honeywell’s UOP technology promises to provide high isobutylene yields, low energy and water consumption, and use of a fully recyclable platinum alumina-based catalyst system. Unique to the Oleflex process, independent reaction and regeneration systems are in place that allow continuous use of catalysts for steady-state operations (non swing-bed), which helps maximize operating flexibility, on-stream factor and reliability.

Since the Oleflex technology was commercialized in 1990, Honeywell’s UOP has commissioned six C4 Oleflex units for on-purpose isobutylene production, as well as nine C3 Oleflex units for on-purpose propylene production. More recently, since 2011, Honeywell’s UOP has announced 10 new Oleflex units across China, Abu Dhabi and North America, including China’s first combined C3/C4 Oleflex unit and the first C4 Oleflex unit.

Longgang Chemical Co. Ltd. is a privately held, professional production and chemical raw materials export enterprise located in Qingdao Province, China.
