This is a plant in which carbon dioxide gas (CO2) contained in exhaust fumes emitted from factories is used as the raw material, and purified, compressed, dehumidified and liquefied to produce high-quality CO2. Research is now under way for using our CO2 separation and liquefaction technology to reduce atmospheric CO2 through underground sequestration of CO2.
A facility we supplied to a company is the largest we have ever built, with a processing capacity of 7,200 m³N/h (9,000 m³N/h after expansion).
By using a system utilizing the waste heat emitted from a liquefaction system and a dry ice press, we were able to achieve reduced facility load and power load and 15% reduction in unit power, while maintaining the quality of the liquefied carbon dioxide.
Gases emitted from plants producing petrochemical, foods and other plants include CO2 as products of combustion, fermentation and other processes.
High-purity liquefied carbon dioxide gas plants separate this CO2 from the exhaust gas and refine it, and then compress it to a liquid state for storage.
The high-purity liquefied carbon dioxidegas produced in such plants can be used in dry ice, or to produce bubbles in carbonated beverages.
We can custom-design (engineering), procurment and construction tailored to customers' requirements based on exhaust gas output volume and material composition.
CO2 from ammonia manufacturing plants, beer breweries, etc. can be captured and refined to produce liquefied carbon dioxide with 99.995Vol% purity. Running costs (power requirements) are 15% lower than before.
We are now developing systems that will be able to separate, recover, and liquefy carbon dioxide emitted in high volume from thermal power plants etc., for subsequent gasification and pressurization.
