PRIETO RIOS, Luis Gabriel; ARTURO CALVACHE, Jaime Eduardo  and  SANCHEZ CORREA, César Augusto. STEP-BY-STEP CALCULATION OF REACTIVE EXTRACTION CASCADES APPLYING THE EQUILIBRIUM MODEL. Rev.EIA.Esc.Ing.Antioq [online]. 2014, n.21, pp.185-201. ISSN 1794-1237.

A step-by-step calculation algorithm for reactive extraction cascade simulation is presented. Theoretical basis is taken from reactive liquid-liquid equilibrium thermodynamics. This method can be applied to parallel, countercurrent and cross-current arranges and operate the most important practical specifications: splitting of solvent and feed streams, location of reaction zone, choice of feed points and specification of transferred heat flow. To illustrate the usefulness of this approach, reactive extraction technological schemes for synthesis of n-amyl acetate from aqueous acetic acid were simulated. Although examples are designed to prove algorithm adequacy, it was also found that the n-amyl acetate production by reactive extraction has strong limitations to conversion and separation. Besides, it is not an interesting alternative to increase the economic value of acetic acid and water streams.

Keywords : Reactive Extraction; Reactive Liquid-Liquid Equilibrium; Esterification Systems; n-Amyl Acetate; Step-by-Step Calculation Algorithm.
