Tokyo, Japan—Tosoh Corporation is building a facility to recover by-product carbon dioxide (CO2) from the operations at its Nanyo Complex, in Shunan City, Yamaguchi Prefecture. The recovered CO2 will be converted into feedstock by the facility and used at the complex as a raw material for the isocyanate products that are among Tosoh’s core products, including in particular for MDI (methylene diphenyl diisocyanate), a raw material for polyurethane. The CO2 and feedstock conversion facility is scheduled to start operation in fall 2024.
At present, Tosoh manufactures naphtha-derived carbon monoxide (CO) as a raw material for its isocyanate products. The new facility will recover approximately 40,000 tons of CO2 a year from the combustion gas released during manufacture at the Nanyo Complex through a process that utilizes proprietary technology. It will then convert the recovered CO2 to produce CO. The switch from naphtha to CO2 will contribute to the company’s low-carbon manufacture of its isocyanate products.
Since summer 2022, Tosoh has been evaluating a proprietary and highly durable amine agent to recover CO2 at a test facility. Tosoh intends to apply that agent at its commercial-scale facilities to reduce their CO2 emissions by capturing and converting the by-product CO2 for utilization in their operations. The company also plans to sell its CO2 recovery amine agent.
Tosoh is committed to contributing to the realization of a carbon-neutral society. The company is taking on this challenge by combining its many years of technological advancements and experience to generate the innovations required for carbon neutrality, in its operations and in society overall.
