The interfacial waves of swirling flow have no apparent periodicity and correlation, similar to the vertical flow. In swirling flow, centrifugal force promotes the accumulation of liquid film mass, reflected in the increase of the substrate liquid film. The circumferential velocity of the swirling flow increases the wall friction stress, reducing the disturbance wave velocity. The superposition of swirling streaks promotes the formation of disturbance waves. Still, the increasing centrifugal force forces the disturbance waves to transfer mass and energy to the ripples, suppressing the formation of disturbance waves. The established correlation for the disturbance wave frequency has a good prediction effect with a mean absolute percentage error of 19.89%.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"8 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758209","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 high drying rates during spray drying produce particle-packed shells saturated with liquid, which may buckle, transforming spherical shells into crumpled granules. The morphology of granules depends on the particle’s mechanical properties and size, interparticle interaction, and drying rates. A recent theory has shown that the morphological transformations are controlled by a dimensionless parameter that measures the competition between the compressive stress generated by capillary forces and the elastic strength of the packing. In this work, we perform experiments on a spray dryer with suspensions containing particles of varying sizes and moduli to test the theoretical predictions. We show remarkable agreement with the theory over many orders of magnitude of the dimensionless parameter. The results provide a fundamental understanding of the morphological changes observed in fast-drying drops containing particles and enable the design of buckle-free granules with desired properties.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"58 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758210","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, traditional selection methods face challenges and inefficiencies when dealing with large pools of molecular descriptors. To address these issues, this study proposes a convolutional neural network (CNN)-based method to automatically identify relevant descriptors, eliminating the need for preselection. This method is applied to predict the flashpoints of pure compounds and mixtures using two different sets of molecular descriptors. Bayesian Optimization is employed to tune the hyperparameters of the CNN models through 5-fold cross-validation. The results demonstrate that the developed CNN models achieve high accuracy, with R2 values of 0.9723 for pure compounds and 0.9939/0.9951 for mixtures in the test data set, outperforming previously established models. Notably, the CNN models maintain high accuracy even when the number of valid molecular descriptors is increased from 125 to 861. Overall, the proposed approach leads to robust performance and accelerates QSPR model development through automated molecular descriptor selection.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"663 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766747","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}

A sequence of SPI-PTDA-X membranes with different sulfonation levels has been prepared and characterized. The stable retention time of the SPI-PTDA-75 membrane in aqueous solution at 80 °C is greater than 240 h; its tensile strength (25.83 MPa) is three times that of N212, and the results of the theoretical calculations of molecular ESP indicate the existence of certain interactions within the SPI-PTDA molecule, being responsible for the enhanced mechanical strength of the SPI-PTDA membrane. Additionally, the vanadium ion selectivity of the SPI-PTDA-75 membrane is approximately double that of the N212. The VRFB with the SPI-PTDA-75 membrane demonstrates a Coulombic efficiency (CE) of 97.59% and an energy efficiency (EE) of 80.47% at 120 mA cm–2.

This study investigates the electrochemical degradation of PET MPs. First, the electrochemical degradation process of PET MPs in aquatic environments was examined. Under the condition of no additional catalyst, the degradation efficiency was measured using a weight loss method, and more efficient electrolysis efficiency was obtained through orthogonal experiment. After 6 h of electrolysis, the weight loss was as high as 68%. The analysis shows that electrolysis temperature is a more critical factor than current density, pH, and surfactant concentration. Second, by studying the changes of soluble organic pollutants in PET MPs and electrolyte with time and temperature during the reaction process, indicating that the increased crystallinity of PET MPs limits the enhancement of degradation efficiency. Furthermore, it was pointed out that the oxidation–reduction reaction of the electrode reaction was enhanced by the surfactant. Combined with the active species analysis, hydroxyl radicals (•OH) and sulfate radicals (SO4•–) play a role in the degradation of PET MPs. The mechanism of electrochemical degradation of PET MPs was hypothesize. The electrochemical degradation method used in this study is characterized by a short treatment time and high efficiency, providing a feasible solution for improving microplastic degradation efficiency, and also provides an effective reference for electrochemical degradation of insoluble pollutants in water.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"61 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758211","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, its demonstration has primarily been at the lab-scale, with water flux and recovery values that are not representative of realistic applications. In this work, the performance of tetrabutyl-phosphonium trifluoroacetate (P4444TFA), as well as a new dual draw of P4444TFA with tetrabutyl-ammonium trifluoroacetate (N4444TFA) is characterized. The dual draw combines the higher osmolality of one IL with the lower critical solution temperature (LCST) of the second IL to outperform its constituents at the same total concentration of IL in water (70 wt %). Experiments were first performed in a lab-scale coupon tester to understand the effects of draw osmotic pressure and viscosity on water flux through the membrane. Bench-scale experiments were then performed in an element tester with a 1 m2 membrane area to evaluate the performance of IL-based FO for the desalination of produced water feed from oil and gas. Specifically, 10 kg of IL-water draw solution was used with 3 kg of real produced water feed, resulting in water recoveries of 60% with initial and final water fluxes of 14 LMH and 3 LMH, respectively. The bench-scale experimental results were used as inputs for a cost analysis, yielding a levelized cost of water (LCOW) of $1.18 per m3. This reveals the potential of IL-based draw solutions for cost-effective desalination of challenging feedwaters using FO.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"24 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758212","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}
