“…In light of these observations, it can be concluded that key process variables need to be adjusted carefully throughout the process in order to achieve an increase in system performance. Rahimpour et al [41] point to this aspect by explaining that better control of both temperature and hydrogen concentration leads to enhanced product qualities, and improved process performance. The above theoretical considerations provide the basis for conceptualizing the most appropriate reactor design below.…”

“…It is significantly faster and more robust than other evolutionary algorithms, its success lying in: spontaneous self‐adaptability, diversity control and continuous improvement . These advantages make it suitable for a large domain of problems, in chemical engineering being applied (in different forms) for model and process optimization of fermentation systems , fuels and oil production , process synthesis .…”

In this paper, an optimal artificial neural network determined by a self-adaptive differential evolution approach is applied to model and optimize the removal of copper from wastewater by an ion-exchange process. The Purolite S930 1 resin with iminodiacetic group was used in batch mode for Cu(II) removal from synthetic aqueous solutions in different working conditions (initial solution pH, stirring rate, initial concentration of copper, temperature, contact time and resin amount). The obtained results indicated that the used methodology was able to provide good models for the studied process, the mean squared error in the testing phase obtained by the best network being 0.0034. In addition, the optimal combination of parameters leading to the maximization of removal efficiency determined with the proposed approach was experimentally validated, the prediction being in correlation with the observed data.

“…Unlike steam reforming, CPOx can exothermally or autothermally convert logistic fuels with oxygen to hydrogen and synthesis gas in catalytic channel reactors. For both reforming processes, temperature control is a dominant parameter in the design of a reactor [11,12]. Improper temperature control will easily result in either hot spots or a very low degree of conversion.…”

This paper proposes a method to model hydrocarbon reforming by coupling detailed chemical kinetics with complex computational fluid dynamics. The entire chemistry of catalyzed reactions was confined within the geometrically simple channels and modeled using the low-dimensional plug model, into which the interactive thermal control of the multi-channel reforming reactor has been implemented with a tail-gas combustor around the external surface of these catalytic channels. The geometrically complex flow in the tail gas combustor was simulated using FLUENT without involving any chemical reactions. The influences of the conditions at the reactor inlet such as the inlet gas velocity, the inlet gas composition and the variety of hydrocarbons of each channel on gas conversions were investigated numerically. The impact of the tail gas combustor setup on the efficiency of the reforming reactor was also analyzed. Methane catalytic partial oxidation (CPO x ) and propane steam reforming (SR) were used to illustrate the approach reported in the present work.
