UOP technology selected for petrochemical production in China
UOP LLC (Des Plaines, Ill.; www.uop.com), a Honeywell company, announced today that its UOP Oleflex process technology has been selected by China’s Longgang Chemical Co. (Qingdao Province, China) to produce key ingredients for fuels and synthetic rubber.
The C4 Oleflex process will be used to convert refinery-derived isobutane to isobutylene, a valuable 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, UOP will provide basic engineering, catalysts, adsorbents, specialty equipment and engineering for the project.
“As the demand for petrochemicals grows, especially in China, producers are looking for ways to maximize product yields while reducing production costs,” says Pete Piotrowski, senior vice president and general manager of UOP Process Technology and Equipment business unit. “Honeywell’s UOP technology will help China meet growing demand efficiently and more profitably. This project is yet another milestone for UOP’s Oleflex technology, and we look forward to working with Longgang Chemical.”
Longgang Chemical Co. will use UOP’s 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. Compared with competing processes, the UOP C4 Oleflex technology provides the lowest cash cost of production, the highest return on investment and the smallest environmental footprint. The superior performance of Honeywell’s UOP technology stems from its low capital costs, high isobutylene yields, low energy and water consumption, and use of a fully recyclable platinum alumina-based catalyst system, says the company.
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, UOP has commissioned six C4 Oleflex units for on-purpose isobutylene production, as well as nine C3 Oleflex units for on-purpose propylene production.
Since 2011, Honeywell’s UOP has announced ten 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.
