CO2 recovery and liquefaction

CO₂ liquefaction is the process of converting gaseous carbon dioxide into its liquid form, making it a versatile and transportable resource. This transformation allows for efficient storage, transportation, and utilisation of CO₂ in various applications.

CO₂ liquefaction plays a crucial role in carbon capture and storage initiatives. By capturing CO₂ emissions from industrial processes, we avoid releasing that CO₂ into the atmosphere, thus not incrementing GHG concentration. The subsequent step of CO₂ liquefaction allows for different kind of usage: from safe transportation and permanent storage underground or in depleted oil and gas reservoirs, to its integration into various industrial processes.

As Pietro Fiorentini, we can integrate CO₂ recovery and liquefaction systems with upgrading plants. This allows to capture and transform the off-gas coming from biogas upgrading into high-quality valuable product. With the use of advanced technologies such as membrane upgrading and a new distillation process, our systems can successfully purify and liquefy CO₂ avoiding methane slip form the upgrading process. The final product is liquid food-grade CO₂ that can be used in the food and beverage sector as a green substitute of the fossil CO₂ previously used.
