Dehydrogenation

Texas will provide $1 million to close a deal with Ascend Performance Materials Texas Inc. to build a propane dehydrogenation (PDH) facility near Houston, Gov. Rick Perry said.

Enterprise Products Partners LP has sold out capacity at its planned 1.65 billion pounds/year propane dehydrogenation (PDH), which is scheduled to begin operation during the third quarter of 2015. In anticipation of a continuing decrease in supplies of propylene, Enterprise is in talks with additional customers that could lead to the development of additional PDH capacity, the company said. Last June Enterprise said it would build a PDH facility on the Texas Gulf Coast that would consume up to 35,000 b/d of propane to produce 1.65 billion pounds/year (750,000 metric tons per year or 25,000 b/d) of polymer-grade propylene (PGP) (see Shale Daily, June 22, 2012). The facility is to be integrated with the partnership’s existing propylene fractionation facilities, which have capacity of 5.3 billion pounds/year. The PDH facility will also be integrated with Enterprise’s PGP storage facilities, 102-mile distribution pipeline system and export terminal. “This [PDH capacity] demand is being driven by the combination of a 38% decrease in propylene supplies since 2006 due to additional ethane consumption by U.S. petrochemical companies and the growing supplies of domestic propane from the U.S. shale plays,” said Jim Teague, COO of Enterprise’s general partner.

TPC Group Inc. plans to produce on-purpose isobutylene with the refurbishment and restart of dehydrogenation assets at its Houston operations. The isobutylene feedstock will be used for the company’s performance products and fuels business, including methyl tertiary-butyl ether, polyisobutylene, high-purity isobutylene and diisobutylene. Start-up is planned for the second half of 2014. The facilities will produce up to 650 million pounds per year of isobutylene from isobutane, a natural gas liquids feedstock whose production volumes continue to increase as a result of U.S. shale gas development, TPC said. Total capital expenditure for the project is estimated at $265 million. TPC recently agreed to be taken private by First Reserve Corp. and SK Capital Partners in a cash-and-debt transaction valued at $850 million (see Shale Daily, Aug. 30).

Williams late Thursday said it is drawing up plans to build the first propane dehydrogenation (PDH) facility in Canada, which would give it room to increase its polymer-grade propylene production to serve a growing petrochemical market.

Enterprise Products Partners LP plans to build one of the world’s largest propane dehydrogenation (PDH) units on the Texas Gulf Coast to take advantage of abundant supplies of propane thrown off by shale gas plays and to address periodic shortages of propylene in the region.
