It introduces an innovative approach for building a GHE-DT that connects the physical and digital systems to monitor key parameters, predict issues, and optimize energy efficiency. The process involves several phases including implicit knowledge codification, data-driven analysis, model construction, and system design. The study emphasizes real-time monitoring of the effective parameters: ground temperature and fluid conditions (flow rate, temperature, and pressure). The GHE-DT's digital system mainly comprises three sections, namely, data storage, mathematical modeling, and data-driven modeling. The role of the presented mathematical model is to simulate the GHE's behavior and assess its performance characteristics, such as the heat exchanger's effectiveness and efficiency. Additionally, the data-driven model used in the proposed DT utilizes formal concept analysis and relation concept analysis to identify connections and associations among parameters for a better understanding of the GHE functioning. The GHE-DT provides useful services including trend analysis, problem prediction, and correlation analysis. These services provide engineers and operators with the opportunity to increase dependability, save maintenance costs, and optimize GHE performance.</p>","PeriodicalId":10083,"journal":{"name":"Chemical Engineering & Technology","volume":"48 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143112245","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}

These data were then fitted to the Apelblat and Van't Hoff equations, and the corresponding model parameters were determined. The effects of stirring intensity and cooling rate on the width of the metastable zone of sodium hypophosphite in water were studied. The findings indicated that an increase in stirring intensity reduced the width of the metastable zone, whereas an increase in cooling rate resulted in its widening. The self-consistent NýVlt and Sangwal metastable zone models were employed to calculate nucleation dynamic parameters in conjunction with classical nucleation theory. The results showed that the nucleation order was 2.311–3.361 over the investigated temperature range. 316.15 K is the critical temperature point at which sodium hypophosphite transforms into a dominant nucleation mode.

Cryogenic distillation is also viewed as the most reasonable separation option for handling CO<sub>2</sub>-EOR gases, despite being an energy-intensive process. The main challenge for this technology is energy loss. To overcome this challenge, one potential alternative is to optimize the system processes and parameters. This study proposes a new process to reduce distillation energy consumption by refluxing the distillate back to the distillation column. Operational parameter optimization was performed using the commercial simulator Aspen HYSYS for modeling and sensitivity analysis of process parameters using orthogonal experimental methods. The simulation results indicate that after optimization, the energy consumption in the distillation process decreased from 0.207 to 0.196 MJ kg<sup>−1</sup>, whereas the purity decreased slightly from 94.63 % to 94.52 %.
