Japan C4 Raffinate Industry Trends and Drivers:

The C4 raffinate segment in Japan is expected to record continuous strong growth due to the presence of developed petrochemical industry, prevalence of downstream derivative production and high refinery and chemical value chain integration. Raffinate I and Raffinate II streams are used as feed streams in the production of methyl tert-butyl ether (MTBE), secondary butyl alcohol (SBA), methyl ethyl ketone (MEK) and butadiene extraction. Although MTBE usage in gasoline may be in a phase-out due to environmental regulations, its use as a solvent, a chemical intermediate and industrial chemical still remains. Raffinate II is also used as a source of isobutylene and butene-1 for the polymer and synthetic rubber industry and fluid cracking catalyst.

Japan's refinery industry has been working to continue optimizing the use of C4 with changes in crude prices and as lighter refined product demands are reduced. Automobile, construction and chemical production growth and improved separation and purification processes also help downstream markets and are expected to continue to improve product yield and reduce costs. In aggregate, they help sustain moderate but steady volume growth of Japan's advanced, integrated C4 raffinate market among a challenging operating environment.
