They used ,CO 2,-H 2 O, ,CO 2,-ethanol and ,CO 2,-n-propanol systems to evaluate performance of proposed method in square channels with dimensions of 40×240μm, 100×800μm, and 100×2000μm. The results showed that the channel diameter and the capillary number are effective parameters on the mass transfer rate, and the maximum value of the mass transfer coefficient is achieved in annular flow regime.
