In order to obtain a homogenous supercritical solution, a numerical simulation based on energy and mass balances inside a column packed with small glass balls and crossed by CO 2 at high pressure, facilitates the analysis of the influence of certain parameters of the process on the extraction rate, e.g., temperature and CO 2 velocity. This contribution aims to study heat and mass transfer mechanisms in both liquid and supercritical phases.
