Pressurized fluid extraction (PFE) of valonea tannin with binary H2O–CO2 and ternary H2O–CH3OH–CO2 systems and phase equilibrium studies
Abstract In this study, the effect of binary and ternary systems, solvent/feed (S/F) ratio (20–100 w/w), time (2–3 h) and pressure (10–200 bar) were tested with subcritical and supercritical CO 2 toExpand
