Yantai Wanhua Polyurethanes Group Co. Ltd., is using Honeywell UOP's C3 Oleflex process technology to convert propane into 750,000 metric tpy of propylene, the primary component used for making plastics, packaging and synthetic fibers. With this unit, the global production capacity of Oleflex technology is now approximately 6.8 MMtpy.

"As China's largest Oleflex unit, this represents a significant expansion in the country's propylene capacity and a big step toward meeting local demand for propylene," said Mike Millard, vice president and general manager of Honeywell UOP's Process Technology and Equipment business. "No other technology works as efficiently and produces as much high-quality propylene as the Oleflex process."

China consumes more than 15% of the world's propylene and its demand is growing more than 4% per year, according to the US Energy Information Administration.

Since 2011, Honeywell UOP's Oleflex technology has been chosen for 40 of the world's 47 new propane and isobutane dehydrogenation projects licensed worldwide.

In addition to technology licensing, Honeywell UOP provided the engineering design, equipment, staff training, technical service and catalyst for the project. The Oleflex unit is part of a large complex that also includes Honeywell UOP LPG hydrotreating technology, a Butamer C4 isomerization unit, and PSA, or pressure swing adsorption, units to produce high-purity hydrogen.
