Subsequently, the equilibrium solubility and in vitro dissolution of the cocrystals were evaluated. The results indicate that the equilibrium solubility of the Imc-Inh cocrystal is 3.2 times that of Imc, and the maximum dissolution of the Imc-Iso cocrystal is approximately 4 times that of Imc. The mechanism underlying the formation of the Imc-Iso, Imc-Inh, and Imc-Sa cocrystals was investigated through the thermodynamics of the cocrystal formation and the calculation of DFT-D. The results demonstrate that the Gibbs free energy change (ΔG), the formation enthalpy change (ΔH) of the Imc cocrystals with Iso, Inh, and Sa are less than zero, indicating that the formation of cocrystals is spontaneous and driven by enthalpy. As the temperature rises, the values of ΔG of the cocrystals formation demonstrate a gradual increase, indicating that elevated temperatures are not favorable to cocrystal formation.

The research on both aspects has been ongoing without interruption. Existing coupled designs of heat exchanger networks and heat exchangers often assume steady-state stream characteristics, neglecting the impacts of flow rate fluctuations and fouling effects on network and exchanger performance. This paper introduces flow uncertainty and fouling models into the synthesis of heat exchanger networks and detailed heat exchanger design. The chance constrained programming method is employed to design heat exchanger networks under uncertainty conditions, with utilizing Set Trimming to optimize heat exchanger. The objective is to minimize the total annual cost of the heat exchanger network. Five scenarios are designed to explore the relationships among uncertainty, fouling, and economy. Additionally, sensitivity analyses are conducted on the magnitude of uncertainty and confidence levels. The results indicate that the threshold fouling model can reduce the equipment investment cost slightly, by about 1 %. The synthesis of the heat exchanger network under uncertainty can improve its resistance to fluctuation. The flexibility index can be increased by 75.6 % by only a 3.5 % increase in operating cost.</div></div>","PeriodicalId":10019,"journal":{"name":"Chemical Engineering Research & Design","volume":"218 ","pages":"Pages 525-538"},"PeriodicalIF":3.7,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070315","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}
