The Dow Chemical Company has announced that its new world scale propane dehydrogenation unit (PDH), located at the company’s Oyster Creek site in Freeport, Texas, successfully completed the performance test, certifying that the unit is operating at full capacity, and is meeting the Honeywell UOP Oleflex™ performance guarantee. The new 750 000 tpy facility began commercial operations in December 2015 and completed the performance test in less than two months.

These milestones represent progress of Dow’s comprehensive investment plan to further connect its US operations with cost advantaged feedstocks from increasing supplies of US shale gas and deliver long term competitive advantage for Dow’s Performance Materials, Consumer and Infrastructure Solutions businesses.

“Dow’s world scale PDH unit has reached full rates and passed acceptance testing in record time,” said Jim Fitterling, Dow’s President and Chief Operating Officer. “The unit enables the replacement of purchased propylene with cost advantaged production that will ultimately enable growth in attractive markets across North and South America. The timing of Dow’s strategic growth investments on the US Gulf Coast has afforded us first mover advantage.”

Dow also continues to make significant progress on its world scale ethylene unit, supporting infrastructure and the derivative investments aligned to the company's Performance Plastics franchise, located at Dow sites across the US Gulf Coast. The completion of the Performance Plastics derivative investments will be synchronised with the new ethylene unit.

“The successful startup of UOP’s Oleflex unit at Dow’s Gulf Coast facility is a major milestone in our ability to provide world class technology that enables companies, like Dow, to use domestic shale gas resources to produce key petrochemicals in the US,” said Mike Millard, Vice President and General Manager of Honeywell UOP’s Process Technology and Equipment business. “In addition to technology licensing, UOP provided the basic engineering design, modular CCR, control systems, catalyst, adsorbent and startup services for the unit, which reached acceptance in record time.”
