Entropy Generation Minimization for Reverse Water Gas Shift (RWGS) Reactors

“…Reference parameters are set according to actual engineering standards, which are derived from Refs. [ 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 61 ]. The settings are listed in Table 2 , the reservoir temperature profile is simulated as for the reactor.…”

“…Ref. [ 47 ] found the optimal numerical solutions by the nonlinear programming (NP) method where a fine grid (300~400 points) must be used to find stable solutions. The algorithm introduced here uses the optimal solution by the NP method to create an initial guess for the bvp4c solver.…”

“…FTT, also known as entropy generation minimization (EGM) [ 31 , 32 , 33 , 34 , 35 ] in engineering, can obtain the optimal performances and optimal configurations of various energy conversion devices and systems subjected to finite-time and/or finite-size, and the optimal results obtained are more powerful to guide thermal designs and optimizations of real-word devices. The wide applications of FTT in chemical reactions, heat and mass transfer processes have obtained many important theoretical achievements [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ]. Månson and Andresen [ 36 ] firstly applied FTT to obtain the optimal paths of ammonia reactor with the maximum production rate as the objective function.…”

“…This equipartition of entropy production (EoEP), but also the equipartition of force (EoF) are good approximations to the state of the minimum EGR in the parts of some plug flow reactors with sufficient freedom. Ao et al [ 47 ] obtained optimal temperature configurations of the tubular steam reformer with linear phenomenological heat transfer law based on EGM, which is different from those with the Newtonian heat transfer law [ 44 ]. The chemical engineering processes, including ideal reactors, and the units both upstream and downstream, are also optimized with the minimum EGR as the objective function.…”

Entropy Generation Rate Minimization for Methanol Synthesis via a CO2 Hydrogenation Reactor

“…Nummedal et al [ 46 ] studied the SMR reactor with the EGR minimization as the optimization objective and obtained the optimal EWT profile. Ao et al [ 47 ] and Chen [ 48 ] et al also studied the performances of SMR reactors with the heat transfer laws of linear phenomenological [ 47 ] and Dulong-Petit [ 48 ], respectively, and obtained the optimal EWT profiles. van der Ham et al [ 42 ] optimized the performance of a sulfuric acid decomposition reactor and obtained two pathways to reduce the EGR in the reactor.…”
