Traditionally, supply chains are designed through deterministic optimization models. However, these models require significant simplifications to mathematically represent the equipment design in these supply chains because of the complexity and nonlinearity these formulations bring to the problem, often leading to suboptimal solutions. This work proposes a novel methodology integrating deterministic and metaheuristic optimization techniques to address this challenge comprehensively. By combining these methods, the approach optimizes supply chain logistics and equipment design, enhancing overall performance, cost-efficiency, and sustainability. A case study on the polystyrene supply chain in Mexico demonstrates the effectiveness of our strategy, showcasing significant economic, environmental, and operational benefits. Two different schemes were used, a direct separation sequence and an indirect separation sequence. The results show that the direct separation sequence is better both economically and environmentally, due to the high energy consumption of the indirect separation. This integrated approach offers a robust mathematical tool for decision-making, setting a new standard in supply chain optimization.</div></div>","PeriodicalId":10019,"journal":{"name":"Chemical Engineering Research & Design","volume":"214 ","pages":"Pages 93-104"},"PeriodicalIF":3.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143101415","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}

Key challenges include managing the variability of renewable resources and complying with local regulations, while also addressing gaps in literature, particularly the impact of time-dependent efficiency profiles on energy sharing within microgrids. By employing innovative analyses and clustering techniques, the research optimizes microgrid configurations, accounting for seasonal demand fluctuations and the influence of incentive policies on system feasibility. The findings reveal that incorporating a time-dependent efficiency model can reduce total costs by 45 %. This reduction underscores the importance of accurate efficiency predictions, as the model captures variations in energy generation and utilization efficiency over time, improving system optimization.

To address this limitation, we selected silver sulfide (Ag₂S) Nanoparticles (NPs) for incorporation into a polysulfone (PSF) membrane, aiming to enhance the photothermal membrane distillation (PMD) process. Ag₂S was chosen due to its unique photothermal properties, including efficient light absorption and conversion into heat, making it an ideal candidate for improving the thermal efficiency of MD membranes. The Ag₂S NPs were synthesized using the Chemical Bath Deposition (CBD) method and characterized through SEM, UV-spectroscopy, FT-IR, and EDX. The NPs were integrated into the PSF membrane at varying concentrations (0.5–2 %). The PSF/Ag₂S composite membranes demonstrated significant photothermal properties, with surface temperatures rising from 45.7°C to 52.3°C under light exposure. The water flux also improved from 5.4 L/m²h without light to 7.8 L/m²h with light in the optimal membrane containing 1.5 % Ag₂S. Additionally, contact angle (CA) measurements indicated increased hydrophobicity, while liquid entry pressure (LEP) values rose, further enhancing membrane performance. The composite membrane achieved a remarkable salt rejection rate of 99.99 %. These findings suggest that integrating Ag₂S NPs into PSF membranes significantly improves energy efficiency, water flux, and desalination performance.
