Japanese ethylene producers unite for decarbonization

Japanese petrochemical producers Mitsui Chemicals, Mitsubishi Chemical and Asahi Kasei have agreed to co-operate on decarbonization of their ethylene crackers in west Japan, targeting to decide a pathway within the current April 2024-March 2025 fiscal year.

They plan to accelerate carbon neutrality at Mitsubishi Chemical and Asahi Kasei's 496,000 t/yr Mizushima cracker in Okayama prefecture and Mitsui Chemicals' 455,000 t/yr Osaka cracker in Osaka prefecture. The partners aim to introduce biomass feedstocks such as biomass-based naphtha and bioethanol and low-carbon cracking fuels like ammonia, hydrogen and electricity. They said joining forces will enable them to accelerate reducing greenhouse gas emissions, although they have not yet decided any further details.

Mitsui Chemicals has experience in using bio-naphtha and recycled pyrolysis oil at its Osaka cracker.

Japanese petrochemical producers have increasingly united to achieve decarbonization of their production processes, which account for around 10pc of the Japanese industrial sector's carbon dioxide emissions, according to the trade and industry ministry. Mitsui Chemicals, Sumitomo Chemical and Maruzen Petrochemical agreed to study the feasibility of chemical recycling and using bio-feedstocks at the Keiyo industrial complex in Chiba.
