This paper intends to emphasize the importance of adopting an effective recovery method for the solvent, in order to improve acetic acid extraction from the fermentation broth. Thus, liquid-liquid extraction was coupled with solvent recovery by stopping and by simple pseudo-continuous distillation and its recycling, in two different laboratory setups. Experimental procedures were performed with ethyl acetate, diethyl ether, and diethyl ether - hexane mixture, under different flow rate levels of the solvent. The effect of physicochemical properties of contacting phases, operating conditions (temperature, organic flow), and contacting hydrodynamics (number, dimension and ascending time of solvent drops) were investigated. Mathematical modelling of the processes is based on transport phenomena equations and describes the dynamic operation of the plants.
