We present a robust superstructure model that covers various configurations and operational strategies for RO systems. Detailed mathematical and empirical models are developed for the feed water intake section, RO units, pumps, and pressure exchanger. By employing multiobjective optimization techniques, toward a sustainable design, we aim to demonstrate how key performance indicators, such as water recovery, specific water cost (SWC), specific energy consumption (SEC), specific CO2 emissions (SCE), and specific intensity of brine pollution (SIBP), interact with each other and highlight the effects of key design parameters on these trade-offs. The optimization problem, characterized as mixed-integer nonlinear programming (MINLP), is solved using the NSGA-II method. Principal results indicate a close relationship between water recovery, SWC, and SIBP, with SEC showing an inverse trend. Validation against industry-standard software demonstrated the reliability of the proposed models, with an average relative error of 2.7% for permeate production and 8.0% for its concentration. The resulting Pareto fronts are comprehensively discussed, revealing the impacts of expert decisions and the high-level trade-offs between the various design criteria. Case studies and Pareto analyses showed that higher recovery and lower SWC result from higher pressure and fewer pressure vessels, which is the inverse for SEC. Additionally, as stages are added, higher recovery results; however, for similar recovery across various configurations, increasing the number of stages results in higher costs and energy consumption.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"51 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current numerical studies of tapered beds are heavily reliant on homogeneous models or hybrid drag models. The homogeneous models fail to accurately predict the heterogeneous hydrodynamics and bubble behavior within a coarse grid framework, while the hybrid drag models call for preconceived regional division. In this study, a coupled approach by combining the Eulerian multifluid model, the population balance model, and the energy-minimization multiscale model was applied in tapered bubbling beds to study the multiscale flow structures. The model can achieve the prediction of the bubble size distribution in tapered beds under coarse-grid simulations rather than through the image processing of highly resolved simulation data. The results indicate that the bed expansion ratio, macroscopic hydrodynamics, and bubble characteristics can be well-reproduced by a coupled CFD-PBM approach. With an increase in gas velocity, both the mean size and number density of bubbles increase significantly, while the impact of the taper angle is secondary. The tapered bubbling fluidized beds exhibit superior overall particle mixing efficiency compared to traditional cylindrical ones. Furthermore, a simplified steady-state mathematical model for bubble diameter was further developed based on the coalescence dynamics for Geldart B or D particles, and the predictions show encouraging agreement with the experimental data.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"31 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The competitive binding isotherms of mixtures of vanillic acid, oleuropein, quercetin, maslinic, and oleanolic acids in water/ethanol solvents, with the composition ranging from 50/50 up to 100% ethanol, prove the feasibility of the separation of such different classes of molecules. The bioactive compounds in two industrial olive leaf extracts with different crude compositions were separated with the pyridyl-based polymer particles in packed columns, employing multicycle sorption/desorption processes. A polyphenol-rich extract was subjected to separation, resulting in the isolation of fractions containing varying concentrations of specific compounds. For example, a fraction enriched with oleuropein exhibited a concentration of approximately 80% (an enrichment factor of ∼4 in comparison with the crude extract), while glycosylated flavonoids were present at a concentration of around 60% in another fraction (an enrichment factor of ∼12). Additionally, aglycone flavonoids were present in fractions at a concentration of approximately 83% (an enrichment factor of ∼49). On the other hand, the separation of polyphenols and triterpene acids in an olive leaf extract with a high triterpene content was also demonstrated, with a ratio of flavonoids to triterpenoids of approximately 23 in isolated fractions, as compared to approximately 1 observed in the crude extract. The developed approach yielded luteolin with an enrichment factor of approximately 7. These novel achievements are intended to contribute to sustainability and a circular bioeconomy through the efficient industrial valorization of agricultural byproducts.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"30 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143507431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dynamic change of interfacial tension under mass transfer conditions has a significant influence on the accuracy of the simulation, yet it has never been considered in previous study because of the lack of experimental data on dynamic interfacial tension (DIFT). In this study, the DIFT model from previous work (Wang et al., AIChE J. 2024; e18411) is incorporated into the CFD-population balance model simulation to simulate two-phase flow in a pulsed column under conditions of mass transfer. Simulation results, including the cumulative droplet size distribution (Q3) and solute concentration in two phases, are in good agreement with experimental results, demonstrating the necessity of the DIFT model. As height decreases, it is found that the reduction in mass transfer flux and solute concentration, leading to an increase in DIFT, is the reason for the decrease in droplet breakup frequency.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"49 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143507429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Essentially, Pt-based intermetallic catalysts with specific crystal structures not only better maintain the active center structure but also regulate the electronic structure of Pt due to the introduction of a second metal, improve the adsorption capacity to toxic intermediate species, and control the reaction pathway by geometric effects. Specifically, the rich electrons on the Pt surface and the broadening of the d-band can promote O2 and H2O to generate OH–, enhancing the activity of O–H and C–H bonds at various carbon positions of glycerol.

However, suitable characterization methods are lacking. To address this, a novel method was proposed to visualize the distributions of total and accessible amine content within the sorbent particles. In this method, SO2 was selected to label the accessible amine, while scanning electron microscopy and energy dispersive spectroscopy (SEM/EDS) were used to measure the nitrogen and sulfur content, which were further used to calculate the total amine and accessible amine content, respectively. By this method, the total amine content is found to be evenly distributed, which is also higher than the accessible amine content due to the utilization of nitrogen for cross-linking and the diffusion resistance within the particles. For particle sizes larger than a critical size, accessible amine content is higher near the wall and lower at the core. This gradient becomes less pronounced as particle size decreases and becomes uniform when particle size is below this critical size. Therefore, reducing the particle size of solid amine sorbents to below the critical size range (e.g., 250–338 μm in this study) can effectively enhance CO2 adsorption capacity by maximuming the accessible amine cont within the sorbent particles.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"210 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
