“…These types of integrated arrangements have been proven to have substantial energy savings [2,63,64]. However, the potential drawback of the multi-effect system preventing the process from being commercialized is the operational difficulties owing to the nonlinear, multivariable and interactive nature of the process [61].…”

“…If fully thermally coupled sequences are considered, these configurations were introduced by Petlyuk [1]. The presence of two vapor transfer streams from the same column, limited their applicability even if the steady-state analysis proved a consistent energy reduction compare to the classical simple column design [2][3][4][5]. This aspect catalyzed the study of new designs which were able to overcome the problem of vapor transfer from one column to another [6,7].…”

a b s t r a c tThe purification of bioethanol is traditionally performed by extractive distillation using three column sequences. In the present work new arrangements composed of two columns are considered for the analysis of control properties. The control properties study was based on the controllability properties under open loop operation, followed by the dynamic behavior for common industrial operating disturbances. Simulation results were analyzed by the singular value decomposition technique. The results from the theoretical control properties indicate that the presence of a side stream in the extractive distillation sequences does not necessarily provide operational disadvantages. The results also suggest that control properties are ruled by the kind of solvent used. The best performances were obtained when glycerol is used as entrainer.

“…The TCDS-SR and TCDS-SS tend to receive special attention [17,18]. Several studies have shown that distillation sequences with side columns typically can achieve energy savings of around 30 % over conventional direct or indirect distillation sequences [19,20].…”

Reducing Energy Consumption and CO₂ Emissions in Thermally Coupled Azeotropic Distillation

The design and optimization procedures of a heterogeneous thermally coupled azeotropic distillation sequence with a side stripper (TCADS-SS) for the purification of isopropanol has been investigated. The proposed procedures can detect the optimal values of the design variables and thereby guarantee the minimum energy consumption, which is related to the minimum CO 2 emissions and the lowest total annual cost (TAC). The procedures are applied to the study of the separation of azeotropic mixtures using the two distillation sequences. In the TCADS-SS, the top end of the side stripper has both liquid and vapor exchange with the main column, which eliminates a condenser in contrast with the conventional heterogeneous azeotropic distillation sequence (CHADS). The results show that not only reductions in energy consumption and CO 2 emissions but also higher thermodynamic efficiency can be obtained for the TCADS-SS.
