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.

The bark of trees contains an interesting mixture of bioactive compounds, or so-called extractives. The use of ,supercritical, carbon dioxide (sc-,CO2,) eliminates both the need for organic solvents as extractants and the danger that solvent traces might compromise the purity of the extracts. Unfortunately, the complexity and natural variability of extracts’ composition render any utilization ...
