Enterprise Products Partners L.P. announced plans to construct a new isobutane dehydrogenation unit in Mont Belvieu, Texas that will have the capability to produce 425,000 tons per year of isobutylene. 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.
