USA: Midstream Energy Services Enterprise Products Expands Natural Gas Processing and Butane Isomerization Capacities

Editor: Alexander Stark

Enterprise Products Partners plans to add 300 million cubic feet per day (MMcf/d) of incremental capacity at its cryogenic natural gas processing facility under construction near Orla, Texas in Reeves County. The partnership also announced plans to expand its butane isomerization facility at its complex in Mont Belvieu, Texas.

Houston/USA — The addition of a third processing train at Orla would increase inlet volume capacity to 900 MMcf/d and allow the company to expand its natural gas liquids (NGL) extraction capabilities by 40,000 barrels per day (BPD) to 120,000 BPD. The third processing train is expected to begin service in the second quarter of 2019 and will complement trains one and two, which are on schedule for completion in the second and third quarters of 2018, respectively.

Mixed NGLs from Orla will be delivered into Enterprise’s fully integrated pipeline system, including the new Shin Oak Pipeline which is currently under construction and scheduled to begin operations in the second quarter of 2019. Residual natural gas from Orla will be transported to the Waha area through a pipeline scheduled to begin service commensurate with the first Orla train, and will connect to the company’s Texas Intrastate pipeline system at the Waha hub.

Upon completion of the expansion projects, Enterprise will have total natural gas processing capacity of more than 1.2 billion cubic feet per day, and the capability to extract more than 200,000 BPD of NGLs in the Permian Basin.

Expansion of Butane Isomerization Facility

The second expansion project announced by the company refers to its butane isomerization facility in Mont Belvieu, Texas. This expansion is supported by long-term agreements to provide butane isomerization, storage and pipeline services, including a 20-year, 35,000 BPD fee-based, tolling agreement. The midstream energy services provider is currently evaluating two options to expand its butane isomerization facilities that would add up to 30,000 BPD of incremental capacity.

Enterprise is the largest commercial producer of high-purity isobutane in the United States. The partnership has 116,000 BPD of butane isomerization capacity at Mont Belvieu. Its isobutane system also includes approximately 13 million barrels of aggregate isom grade normal butane and high-purity isobutane salt dome storage capacity and 162 miles (260 km) of distribution pipelines. Butane isomerization is the process of converting normal butane into high-purity isobutane, which is used as a feedstock for the petrochemical and refining industries.
