Through the use of advanced Equations of State (EoS), the Non-Equilibrium Thermodynamics for Glassy Polymers (NET-GP) theory rose into prominence as a powerful correlative and predictive tool for the sorption of guest species in glassy polymers. The recently proposed Dry Glass Reference Perturbation Theory (DGRPT) provided a method to account for the polymer swelling through the NET-GP framework. In this work, we introduce a second-order modification to the DGRPT that improves upon the model’s flexibility in representing different types of isotherms. We have also investigated different association and parameterization schemes for water and alcohol sorption using the PC-SAFT EoS in glassy polymers. For the non-self associating polymers investigated here, our results concluded that the sorption of alcohols can be represented adequately using the induced association assumptions formulated by Kleiner and Sadowski. On the contrary, the same assumptions often lead to poor water sorption results. We speculate that the Wolbach and Sandler combining rule may be incapable of representing the cross-association effects between water and the glassy polymer.

Traditionally, polycarbonate production involves the use of bisphenol A (BPA) and phosgene (COCl₂), which have raised concerns due to their high toxicity and the overall environmental impact of the process. To address these issues, more sustainable methods such as ring-opening copolymerization (ROCOP) of epoxides and carbon dioxide (CO₂) under supercritical CO₂ (sCO₂) are being developed. Recent research has focused on the synthesis of poly(cyclohexene carbonate) (PCHC) and poly(limonene carbonate) (PLC) from cyclohexene oxide (CHO) and limonene oxide (LO), respectively. Limonene oxide has attracted particular interest due to its non-toxic properties and its derivation from limonene, an available bio-based terpene. Reaction performance is strongly influenced by the initial physical state of the mixture, in particular the composition of the liquid and vapor phases. Therefore, access to this thermodynamic information, represented by phase diagrams, is essential for understanding and predicting reaction behavior. However, there is a lack of equilibrium data for these two systems. The aim of this study is to investigate the phase equilibria of the CO₂/CHO and CO₂/LO binary mixtures, thereby contributing to the advancement of greener polycarbonate production. The experiments were performed in a variable volume view-cell, covering a temperature range from 338.15 K to 363.15 K for the CO₂/CHO mixture and from 303.15 K to 343.15 K for the CO₂/LO system. The molar fraction of CO₂ was varied between 0.189 and 0.967 for the CO₂/CHO case, and between 0.227 and 0.997 for the CO₂/LO mixture. Vapor-liquid bubble point (VLE-BP) and dew point (VLE-DP) were determined for both mixtures, along with mixture critical points for the temperatures studied. The phase behavior was modeled using several equations of state (EoS).

This is essential to overcome current financial and environmental obstacles to implementing large-scale CO₂ capture. In this work, the identified amines to formulate a good aqueous solvent mix are 1-methylpiperazine (1-MPZ) and 2-amino-2-methyl-1-propanol (AMP). 1-MPZ has a higher thermal resistance and lower CO₂ regeneration cost, which makes it a potential candidate for the process. This paper presents the results of experiments on the equilibrium solubility of CO₂ in aqueous 1-MPZ solutions and its blends with AMP along with new vapor pressure data for aqueous 1-MPZ and its blend with AMP. The study examined CO₂ solubility at 0.10, 0.20, 0.30, and 0.40 wt fraction (<em>w</em>) of 1-MPZ and temperatures of 303.15, 313.15, 323.15, and 393.15 K. The CO₂ solubility experiments for the new blended mixture of AMP + 1-MPZ were also performed in this study. Four different sets were prepared by varying the individual concentrations of 1-MPZ and AMP; keeping the total amine concentration 0.40 <em>w</em> for the same temperature range. The experimental results indicate that aqueous 1-MPZ exhibits good cyclic capacity for CO₂ intake which further enhances when combined with AMP. Results indicate that aqueous 1-MPZ exhibits high CO₂ solubility of 0.78 to 1.01 moles of CO₂/moles of amine at normal absorber conditions of temperature and composition. Again, the addition of 1-MPZ to AMP has increased the cyclic capacity. The blended aqueous amine (AMP+ 1-MPZ) shows a cyclic capacity of 118 g CO₂/kg-solution whereas aqueous 1-MPZ of the same amine strength shows only 81 g CO₂/kg-solution. Hence, an increase of about 45% cyclic capacity is achieved with the blended solvent. The combination of 1-MPZ+AMP allows for improved performance in terms of both solubility and regeneration efficiency. The study also incorporated Random Forest (RF) machine learning model to predict CO₂ solubility based on parameters like temperature, concentration, and CO₂ partial pressure. The RF model demonstrated excellent prediction accuracy with R² values of 0.98 and 0.99 for both solutions and least RMSE values of 0.03 and 0.02 for 1-MPZ and (1-MPZ +AMP) blend respectively.</div></div>","PeriodicalId":12170,"journal":{"name":"Fluid Phase Equilibria","volume":"595 ","pages":"Article 114405"},"PeriodicalIF":2.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528887","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}
