Showa Denko Gas Products has announced the construction of a new plant to produce liquefied carbon dioxide (CO2) gas in Showa Denko’s Oita Petrochemical Complex located in Oita City, Oita Prefecture.
Kawasaki/Japan — The plant will utilize stable CO2 gas sources from the chemical plant of the Complex. The new plant is scheduled to be completed and start operation in August 2018, and will have annual production capacity of 15,000 tons.
CO2 gas and dry ice (solidified CO2) are used in many fields including beverage, food, and other manufacturing industries. Liquefied CO2 gas is made of CO2 gas generated as a by-product of oil-refining, steel-making and ammonia production processes. However, the decrease of oil-refining and ammonia production processes in Japan has been reducing sources of raw CO2 gas to produce liquefied CO2. This resulted in a tight supply-demand situation for liquefied CO2 gas and dry ice is the country.
The Showa Denko Group produces and provides liquefied CO2 gas and dry ice at many production bases including Kawasaki Plant, which functions as the main base. To solve tight supply-demand situation and regional supply-demand imbalances concerning liquefied CO2 gas and dry ice, and to maintain stable supply of these products to the company's customers throughout the country, the group has been increasing production at the Kawasaki Plant.
The company is expecting a tight supply situation for raw CO2 in the future. To cope with these problems and maintain stable supply of liquefied CO2 gas and dry ice SDK and SGP decided to establish a new base to produce liquefied CO2 gas at Showa Denko Group’s Oita Petrochemical Complex.
