N2 - As an example of a carbon capture approach, we have developed 2D CFD model in Comsol Multiphysics in which we investigated CO2
absorption in an ionic liquid ([Bmim][TCM]). Factors such as pressure
(1–20 bar), temperature (278–330 K), inlet gas velocity (0.0001–1ms-1),
sparger diameter to column diameter ratio (0.1–0.5), and column height
to diameter ratio (1–3) were investigated. A quadratic model for
absorption behavior (p-value < 0.0001 and R2 0.98) was developed. Four sparger geometries were considered, and
the optimal values for column height to diameter and sparger diameter to
column diameter were computed. The maximum CO2 concentration was obtained at a pressure of 18.26 bar, temperature of 309.5 K, velocity of 0.825 ms-1, sparger diameter to column diameter of 0.414, and column height to diameter of 2.5.
