Taiyo Nippon Sanso Corporation (Headquarters: Shinagawa-ku, Tokyo; President Kenji Nagata; hereinafter "TNSC"), a Japanese industrial gas business company in the Nippon Sanso Holdings Group, has extended the range of raw material carbon dioxide (CO₂) concentrations applicable to CO2 recovery equipment with a capacity of 10 tons per day, which it launched in April 2023, to enable CO₂ recovery from a wide range of CO₂ emission sources.

Background of Development

Following the global trend toward carbon neutrality by 2050, TNSC started marketing CO₂ recovery equipment with a capacity of 10 tons per day in April 2023 to support customers' decarbonization efforts. Since launch, we have received many inquiries from customers wanting to capture CO₂ from emission sources outside the specification range (raw material CO₂ concentration of 20-40%) of the CO₂ recovery equipment. To meet such customer needs, we have extended the range of recoverable CO₂ concentrations (up to 60%) by leveraging our accumulated gas separation and purification technologies. This will allow us to provide more customers with decarbonization solutions by capturing CO₂ emissions from a broader range of sources than previously possible.

CO₂ recovery equipment specifications

Recovered CO₂ amount: 10 tons per day

Recovered CO₂ concentration: 98%

Raw material CO₂ concentration: 20%～60%

Equipment dimensions:14.5×5.35×2.75 m

TNSC is also committed to developing technologies to recover CO₂ from low-concentration (less than 20%) raw material CO₂ emission sources and will continuously contribute to achieving a carbon-neutral society by distributing CO₂ recovery equipment with an extended application range to various customers.
