  • Octane Enhancement
  • Enterprise owns and operates an octane enhancement production facility located in Mont Belvieu, Texas that is designed to produce isobutylene and either isooctane or methyl tertiary butyle either ("MTBE").  The products produced by this facility are used by refiners to increase octane values in reformulated motor gasoline blends. The high-purity isobutane feedstocks consumed in the production of these products are supplied by our isomerization units. To the extent that MTBE is produced at our Mont Belvieu facility, it is strictly sold into the export market.
