“The construction of this new iBDH plant will extend our butane value chain and allow full utilization of our existing olefins assets,” said A.J. “Jim” Teague, chief executive officer of Enterprise’s general partner.

Houston/USA — The project, which is supported by long-term contracts with investment-grade customers, is expected to be completed in the fourth quarter of 2019. The isobutylene produced by the plant will provide the necessary feedstock to fill underutilized capacity at Enterprise’s existing downstream octane enhancement and petrochemical facilities.

Historically, steam crackers and refineries have been the major source of propane and butane olefins for downstream use. However, with the increased use of light-end feedstocks, specifically ethane, the need for on-purpose olefins has increased. The propane dehydrogenation unit is currently scheduled for start of operations in the second quarter of 2017 and will increase production of both high purity and low purity isobutylene to be used primarily as feedstock to manufacture lubricants, rubber products and alkylate for gasoline blendstock, as well as MTBE for export.
