“…In this study, commercial tubular inorganic membranes were selected and the Amberlyst-15 ion exchange resin was considered to be the catalyst and the adsorbent simultaneously. In order to develop a mathematical model able to predict the PermSMBR performance with that materials, the respective reaction, adsorption and pervaporation fundamental data were taken into account, which are available in the literature (Ostaniewicz-Cydzik et al, 2014;Constantino et al, 2015;Constantino et al, 2017). Furthermore, other important assumptions were considered like axial dispersion flow for the bulk fluid phase, linear driving force approximation, membrane concentration polarization, liquid velocity variations, constant porosity and length of the packed bed and isothermal operation.…”

“…Nevertheless, most of them are based on reactive distillation technology, which is very interesting from the industrial point of view. However, besides the fact that the synthesis of BAc involves a very slow equilibrium limited reaction between acrylic acid and n-butanol having water as a by-product (Ostaniewicz-Cydzik et al, 2014), it also presents a high risk of polymerization (Constantino et al, 2015), which is further promoted by the high temperatures used in reactive distillation, as instance. This way, alternative processes able to work at milder temperatures are still required.…”

In this work, a new strategy to improve the synthesis of butyl acrylate was investigated. It comprises the integration of different separation processes with reaction in the same equipment aiming to increase the reaction equilibrium conversion. In this framework, commercial hydrophilic membranes packed with Amberlyst-15 ion exchange resin together with the simulated moving bed technology were considered, in a technology also known as simulated moving bed membrane reactor (PermSMBR). A mathematical model able to predict the PermSMBR performance was developed taking into account the reaction, adsorption and pervaporation fundamental data available in the literature. The results revealed that the PermSMBR can be one of the most effective processes for the synthesis of butyl acrylate achieving better performance than that reached in a simulated moving bed reactor, reducing by 98 % the SMBR desorbent requirement and significantly improving its productivity.

“…In recent years, special attention has been paid to the applications of SMBRs in the chemical and food industries. The application of SMBRs in the reaction processes of glucose isomerization, synthesis of dimethyl acetal from carbonyl compounds, green fuel production, butyl acrylate synthesis, synthesis of 1,1-dibutoxyethane, and high-fructose syrup production have been studied by Rodrigues et al [5][6][7][8][9][10][11][12][13].…”

Simulated moving bed reactors (SMBRs) are hybrid reactors that perform reaction and separation processes simultaneously in a single unit. Their high separation performance and ability to overcome equilibrium constraints on the reaction make them effective in a wide range of equilibrium reactions. This study investigated an SMBR for xylene isomerization and separation of p-xylene from other xylene isomers (free of ethylbenzene) in the liquid phase. The effects of operating variables including temperature, switching time, and columns arrangement on the performance parameters and optimal conditions were determined. Due to the removal of products from the reaction site, the SMBR drives the chemical equilibrium toward producing more product than a conventional reactor under the same conditions.

“…A SMB unit can be used to carry out chemical reactions, forming a SMB reactor (SMBR) [5,6]. Its applications on the intensification of various reactions, such as esterification [7][8][9][10], acetalization [11], etherification [12], hydrogenation [13,14], isomerization [15,16], production of sugar [17,18] and p-xylene [19,20] have been reported. Efficient insitu separation of reactants and/or products is crucial for the conversion enhancement of a SMBR beyond thermodynamic equilibrium.…”

Simulated moving bed reactor (SMBR), a multicolumn multifunctional integrated reactor system, which can be exploited with on-site adsorptive separation to enhance conversion of equilibrium-limited reversible chemical reaction. In this article, for generality, a dimensionless SMBR model was developed and effects of five representative temperature distributions among different zones on the performance of an SMBR for reversible reaction in the general form of a reactant decomposed to two products were evaluated based on simultaneous maximization of unit throughput and product purity. Multipliers were applied to adjust some of the model parameters such that different operation modes can be compared under various conditions in the parametric space. The multiobjective optimization problems were solved using the non-dominated sorting genetic algorithm. All simulations were carried out using FORTRAN codes. The results showed that both kinetics and adsorptive separation play important roles in SMBR. When kinetics is fast or adsorptive potency of the reactant is higher than the desired product (B) but lower than byproduct (C), non-isothermal operation can significantly improve unit throughput. On the contrary, feed concentration and reaction enthalpy have minor effects on the optimal solutions. Decision variables based on flow rate ratios and internal concentration profiles were used to explain the trends of Pareto optimal solution.
