Like most solvolysis processes, hydrolysis lacks selectivity, yielding dilute monomer mixtures that require elaborate downstream purification. To avoid downstream complexity, selective depolymerization is pursued by leveraging differences in polymer reactivity. Variation of temperature and base concentration relative to the base case (polymer-to-NaOH ratio 0.8 mol mol<sup>−1</sup>, 90°C) increase selectivity by 17% and 14%, respectively, at the expense of reaction kinetics. The addition of a co-solvent increases selectivity by 19% while reducing reaction time for PLA by 98%. These findings suggest that sequential depolymerization of PLA and PET can be attained by choosing suitable operating conditions.</p>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"98 6","pages":"304-311"},"PeriodicalIF":1.6,"publicationDate":"2026-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cite.70075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148274825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the separation efficiency of the corrugated plate steam-water separator and reduce the operating cost, a novel corrugated plate steam-water separator is proposed in this study. The optimization effect of the novel corrugated plate steam-water separator is analyzed through numerical simulation methods. The main results are as follows: By comparing the separation performance of two types of corrugated plate separators, the separation pressure drop of the novel separator is significantly reduced. Moreover, the pressure drop decreases progressively with increasing inlet velocity, with a maximum reduction of approximately 40%. While reducing the separation pressure drop, the separation efficiency of the novel corrugated plate steam-water separator remains at the same level. Considering the presence of secondary droplets, the structure of the drainage hook is modified to alter the droplet flow trajectory of large-diameter droplets, adjust the liquid film distribution, and reduce the generation of secondary droplets. The method of graded optimization of the drainage hook structure provides a reference for the structural optimization of corrugated plate steam-water separators.</p>\u0000 </div>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"98 6","pages":"312-325"},"PeriodicalIF":1.6,"publicationDate":"2026-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148274793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a comprehensive mathematical model of a fluidized bed dryer is developed, incorporating mass and energy conservation for both gas and solid phases. The heat and mass interaction between solid particles and the gas phase is described utilizing the reaction engineering approach. Instead of assuming perfect back-mixing, the evolution of gas properties is resolved along the bed height. This allows for the assessment of the impact of the initial mass of wet solid particles in the bed on drying kinetics. The obtained results indicate that the proposed model exhibits better predictive performance compared to previously published studies. Therefore, the model can be considered a useful tool for accurately predicting transport phenomena in fluidized bed drying systems.</p>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"98 6","pages":"292-303"},"PeriodicalIF":1.6,"publicationDate":"2026-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148274889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
