Resumen/Descripción – provisto por el repositorio digital
The main objective of this work in the area of batch distillation is to develop models in order to evaluate new alternatives of separation (design, synthesis and simulation of processes) and to optimize its performance (dynamic optimization). In continuous distillation the purpose is to develop a procedure of initialization of decision variables involved in the optimum synthesis of complex distillation systems. In both cases the models are based in reversible distillation, which theory is commonly referred as “pinch theory”. The modeling of this type of columns gives enormous information for the synthesis of these processes because it makes possible reliable estimations of minimum energy demand that entails each column of a sequence (continuous distillation) or each stage that forms the discontinuous operation of one or more distillation columns. The theory of reversible distillation makes possible the estimations of feasible products (continuous distillation) or the maximum recoveries of distillate products. The minimum energy demand and feasible products are often affected by non-idealities of mixtures (solutions) that entail the appearance of “tangent pinch points” and distillation boundaries. These phenomenons are studied using the analysis of bifurcations of reversible profiles. Thus, “pithfork” bifurcations in reversible profiles allow the evaluation of maximum feasible separation while “saddle node” bifurcations are associated to the appearance of “tangent pinch points”, which affects the minimum energy demand.
