Optimization of reagents injection in a stirred batch reactor by numerical simulation

Impact of Fluid Flow on Free Radical Polymerization in a Batch Reactor

“…Global residual tolerances for all variables (velocity, continuity, k-) were kept constant at 1 × 10 −3 . Realizable kwas selected due to its reduced convergence time (1305 iterations), this being compatible with the literature recommendation for high-velocity rotational flows [25,26].…”

“…The mixing time for tracer 1 has a value of 15.4 s and for tracer 2, a total of 35.8 s (Figures 18 and 19). The criterion used to define the mixing time was the standard deviation of the concentration data registered in all monitors [26]. The experimental and numerical mixing times are shown in Table 6.…”

Analysis of Mixing Efficiency in a Stirred Reactor Using Computational Fluid Dynamics

“…Some authors have been testing this by inducing turbulence effects on solid-liquid suspensions to solve problems related to polymerization [20][21][22][23]. Rahimi, Lassin, and others studied hollow impeller effects to validate experimental fluid dynamics using CFD in order to evaluate the influence of the impeller speed [28][29][30]. Some authors simulated lead bullion in hemispherical vessels known as kettles [9][10][11][12]14,15,[31][32][33][34].…”

“…Other authors have studied the effect of perturbations in stirred tanks [19][20][21][22][23][24][25]30,[35][36][37][38]. Others have been analyzing chemical reactions and the evolution of liquid-liquid phases [17][18][19][20][21][22][23][26][27][28][29][36][37][38][39][40]. Murthy, Zhong Zhang, Sossa-Echeverria, Szalai, and others have dedicated their works to evidencing the influence of tanks and impeller geometries [16][17][18][19][20][21][22][23]35,36].…”

A Novel All-in-One Real-Time Optimization and Optimal Control Method for Batch Systems: Algorithm Description, Implementation Issues, and Comparison with the Existing Methodologies

“…For these reasons, many authors focused on batch processes to find efficient solutions to make them more automatic and better controlled. Most of the times model-based control techniques (proposed for the first time in ref ) have been used with the aim of improving safety and optimizing intrinsically batch operations. − Several authors have also shown the potential for applying the dynamic optimization to batch systems, − studying in detail even the most appropriate control methodology to be selected and employed. , Moreover, both for optimal control and dynamic optimization, the best ways to perfom the process modeling have also been addressed …”
