METHOD AND APPARATUS FOR CO2 CAPTURE

摘要

Disclosed is a method for capturing C02 from a gas stream (10) by introducing droplets of an absorption liquid (15, 17, 40) into the gas stream mainly in the flow direction of the gas. According to the invention, CO2 is captured from the gas stream during a capture phase by means of the absorption liquid droplets, where the absorption liquid droplets are airborne during the capture phase, absorption liquid droplets are introduced into the gas stream with a velocity high enough to ensure internal circulation inside the absorption liquid droplets, and the absorption liquid droplets are introduced into the gas stream with a Sauter mean diameter in the range of 50 10E-6 m - 500 10E-6 °m. An apparatus suitable for conducting said method is also disclosed.
