Honeywell announced that Enterprise Products Partners LP will use Honeywell UOP’s C3 OleflexTM technology in its second propane dehydrogenation plant, called PDH 2. Located near Mont Belvieu, Texas, US, PDH 2 will produce 750 000 tpy of polymer-grade propylene as part of Enterprise’s expansion of propylene manufacturing capacity.
Honeywell UOP will provide licensing for the Oleflex technology, in addition to engineering, catalysts, adsorbents, services, and equipment for the plant. Enterprise has operated a UOP C4 Oleflex unit, which converts isobutane to isobutylene, since 1993 and currently is building a second C4 Oleflex unit at Mont Belvieu.
“Due to the demonstrated economics and reliability of the Oleflex process, Enterprise determined this technology provides the best option to expand its propylene production capacity,” said Bryan Glover, Vice President and General Manager, Honeywell UOP’s Petrochemicals and Refining Technologies business. “It will help Enterprise take advantage of low-cost propane and meet the rising demand for on-purpose propylene.”
The new propane dehydrogenation unit will have capacity to produce up to 1.65 billion lb/yr of polymer grade propylene. The unit is scheduled to begin service in the first half of 2023.
