Processo e apparato per il recupero della CO2

Process for recovering CO2 from a pressurised gaseous process flow containing CO2, comprising the following steps: a) the CO2 contained in said gaseous process flow is absorbed in water at a pressure between 5 and 100 atm, obtaining CO2-enriched water; b) the CO2 is de-absorbed from the enriched water from step a) at a lower pressure than the pressure of step a) and the gaseous CO2 is separated from the water which is recycled and pressurised again for use in step a), said process being conducted: in a single apparatus (1) comprising: * an absorption section (1a) in which step a) is conducted; and * a regeneration section (1b) in which step b) is conducted wherein said absorption section (1a) and said regeneration section (1b) are in direct fluid communication or two separate apparatuses (1', 1'') consisting of: * an absorber (3) in which step a) is conducted; and * a regenerator (4) in which step b) is conducted wherein said absorber (3) or regenerator (4) are in fluid communication with each other through a duct (5), possibly regulated by a thermal expansion valve (6).
