SDK to establish new liquefied carbon dioxide plant in Japan


Showa Denko’s (SDK) consolidated subsidiary Showa Denko Gas Products (SGP) is set to establish a new facility that will produce liquefied carbon dioxide (CO2) gas in its Oita Petrochemical Complex in Japan. 

With an annual production capacity of 15,000t, the new plant will be used as a carbon dioxide source for the chemical plant of the complex.

The plant is scheduled to begin operations in August next year.

The Showa Denko Group produces liquefied CO2 gas and dry ice (solidified carbon dioxide) at multiple locations, including the Kawasaki Plant. 

"With an annual production capacity of 15,000t, the new plant will be used as a carbon dioxide source for the chemical plant of the complex."

Liquefied CO2 gas is procured from carbon dioxide gas generated as a by-product of oil-refining, steel-making and ammonia production processes.

However, due to the decline in oil-refining and ammonia production activities in the country, the sources of CO2 gas have narrowed significantly to causing a tight supply-demand situation. 

The company has been increasing production at Kawasaki Plant to meet growing demand in the market. However, it opted to establish a new plant anticipating additional demand in the future and also to reduce transportation and raw material costs. 

CO2 gas and dry ice are used in multiple segments such as beverage, food and manufacturing industries.
