Essential oils of chamomile are used extensively for medicinal purposes. Many different chamomile products have been developed, the most popular of which is herbal tea. In this study, a mathematical model is formulated that describes the governing mass transfer phenomena in a solid–fluid environment under supercritical conditions using carbon dioxide. The concept of quasi-one-dimensional flow is applied to reduce the number of spatial dimensions. The flow of carbon dioxide is assumed to be uniform across any cross-section, although the area available for the fluid phase can vary along the extractor. The physical properties of the solvent are estimated based on the Peng–Robinson equation of state. Model parameters, including the partition factor, internal diffusion coefficient, and decaying factor, were determined through maximum likelihood estimation based on experimental data assuming normally distributed errors.

In this paper, grey wolf optimization (GWO) optimized convolutional neural network (CNN)-bi-directional long short-term memory (BiLSTM)-Attention algorithm was used for prediction, and the problem of low SO₂ concentration prediction accuracy at outlet has been resolved. First, the outliers of the thermal power plant desulphurization data were processed using the local outlier factor (LOF) algorithm. Secondly, CNN-BiLSTM model was constructed using CNN and BiLSTM, and attention module was added to realize feature extraction and better capture the regularity of input data. Then, the CNN-BiLSTM-Attention model was optimized using GWO and its hyperparameters were improved. Finally, based on the Matlab R2023a platform, the prediction comparison as well as the error analysis of the desulphurization data were carried out. In the prediction of SO₂ concentration in low-flow continuous slurry supply mode, the error of the combined model decreased by 23.2% on average compared to the CNN-BiLSTM-Attention model. In the prediction of SO₂ concentration in the high-flow intermittent slurry supply mode, the error of the combined model decreased by 20.8% on average.

A discrete method, synthesizing the generalized cell mapping (GCM) together with dynamic programming (DP), with inverse search strategy, using pattern moving theory (PMT) framework, was proposed. The basic idea is to describe and control the system's dynamic peculiarity utilizing pattern class variable in ‘pattern moving space’. First, a few prior concepts were reviewed, including PMT, cell mapping, and optimal control for this kind system. Then, we articulated a cross-mapping method to analyze the system dynamic behaviour, which takes into account the computational and statistical properties of pattern class variable simultaneously. For system optimal control, the improved GCM and cost function were performed to determine the discrete optimal control table (DOCT) in accordance with dynamic programming and inverse search. Finally, simulation results of two cases demonstrate the efficiency and practicality of the proposed approach.

The hydrodynamic flow conditions with MNBs are enhanced compared to the traditional gas bubbling in MD. Specifically, an air cushion is formed between the membrane surface and bulk, limiting the deposition of solid particles on the surface. Also, turbulence created by the MNBs reduces the membrane fouling. The findings of the MD performance analysis showed that, in the absence of nanobubbles, considerable membrane scaling occurred during the treatment of high-salinity feed, which significantly decreased the distillate flux to 70% after 20 h. The one-time incorporation of air NBs into the saline feed significantly reduced salt precipitation or fouling on the polyvinylidene fluoride (PVDF) membrane surface by delaying the start of flux drop and preventing membrane wetting, thus improving MD performance. For nanobubble-assisted MD, the only measured flux drop after 20 h of operation was 57% under similar input concentration and operating parameters.</p>","PeriodicalId":9400,"journal":{"name":"Canadian Journal of Chemical Engineering","volume":"103 6","pages":"2804-2812"},"PeriodicalIF":1.6,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143919415","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}
